Do-it-yourself Karcher hose repair

Karcher washing equipment is popular in the responsible market. Such devices are widely used for domestic purposes. Cleaning walls, doors of houses, garden paths, washing cars, windows, workshops and garages - the strong pressure of water that the machine supplies effectively copes with the removal of dirt and dust. Regular use of the sink leads to wear of structural elements.

Often, equipment owners are faced with the need to repair or replace the Karcher high pressure hose (HPR). Having studied in detail the instructions below, you can easily troubleshoot yourself. In order to save time and effort, you can seek help from professionals. The company "Lengidravlika" offers its services, which is located at the address: St. Petersburg, st. Cast iron, d. 20. Specialists in the shortest possible time will produce the entire range of works.

The Karcher high-pressure hose is one of the basic elements of the hydraulic system of washing equipment. The flexible pipeline is designed to supply water under pressure from the built-in pump to the nozzle of the device. To ensure that the hoses can easily withstand a significant load, reliable, wear-resistant materials are used for their production. The design of the high pressure hose consists of two layers of polymer - it can be either rubber or synthetic rubber. Between the inner and outer parts of the pipeline there is a metal braid, which gives the product additional strength. The wire winding technique is of two types, which has become the basis for the classification of pressure hoses:

• - Braided. The braid is applied at an angle, each next layer is crossed with the turns of the previous one. Such high pressure hoses are designed for a significant level of pressure.
• - Winding. Layers of wire are superimposed in even rows. In terms of endurance, high-pressure hoses of this type are inferior to the previous type of high-pressure hoses.

The market offers a wide range of hoses that differ in rubber thickness, number of braided layers, diameter, length and load capacity - the parameters depend on the area of ​​application of the products. When choosing high-pressure pipes for Karcher, you should be guided by the manufacturer's recommendations.

Failures in the operation of Karcher high pressure washers are often associated with damage to the flexible piping. The hose wears out, rubs, cracks form on it - as a result, a leak occurs. It should be understood that under the influence of significant pressure, the risk of damage to the tubes increases. Another common malfunction is a violation of the integrity of the fittings in Karcher sinks. Fasteners lose their tightness or are affected by corrosion. The causes of damage to the RVD are of the following types:

• - Manufacturing defects. The use of outdated equipment, non-compliance with technologies, lack of product quality control are the main reasons why sleeves with various defects are found on sale.
• — Parameter mismatch. An incorrectly selected high-pressure hose quickly fails.
• — Intensive operation. With prolonged use, under the influence of a constant pressure of liquid, the hose loses its initial properties.

The service life of the high pressure hose depends both on the quality of the pipeline itself and on the reliability of the fasteners. If you notice a fluid leak or a malfunction in the washer, you should clearly identify the place where the fitting or hose is damaged. If you have problems at the diagnostic stage, contact the professionals.Masters of the Lengidravlika company will be happy to assist in troubleshooting Karcher washing equipment.

It is not difficult to qualitatively repair the hose, ensuring stable and long-term operation of the sink, the main thing is to strictly follow the recommendations, perform all actions carefully and carefully. Regardless of the nature of the damage, the RVD should be removed initially. The hoses are attached to the equipment using a thread or a quick coupling - this depends on the model of the machine.

The next steps look like this:

1. 1. After dismantling the tube, cut off the damaged part to the point where there is no deformation.
2. 2. If the sleeve is damaged at the end or the fastener is broken, select a similar fitting and crimp it with a vice.

3. When a cut has formed along the length of the high pressure hose, a connector of a given diameter is used for repair, as well as two clamps. They help to seal the joints of the sleeve. Similar work is carried out if it is necessary to lengthen the tube or connect two hoses.

What if the cracks go along the entire sleeve? In such a situation, it is rational to purchase and install a new tube. The Lengidravlika company, a domestic manufacturer of high pressure hoses and end fittings for Karcher washing equipment, will offer a quality alternative. Our specialists know exactly how to repair a hose or find a worthy replacement for it. Clients expect affordable prices for work, prompt execution of orders, a responsible approach to solving tasks.

If the hose is torn off the flange, then you need to cut off the damaged section of the hose evenly, to the point where there are no extensions, cracks and undamaged cord.

Next, purchase the necessary flange and install it - fortunately, a large number of them are sold in auto stores and there is also a choice. The flange is inserted into the hose and simply crimped well with the help of a stop in the vise jaws and hammer blows from the third upper side.

If the damage is somewhere along the length of the hose, for example, a cut, a rupture, or something else, then we do exactly the same as in the first case, cut the hose and cut it to a whole, but here a connector of the desired diameter and a pair of clamps will help - just buy clamps not cheap, but good ones like those in the photo!

Repairing a high-pressure hose at Karcher is an almost hopeless business. If it is damaged in a straight section, crushed, chopped, and so on, then finding a double-sided Christmas tree branch pipe and compressing it at home on a hose is very problematic. You can do without buying a new (very expensive) hose only if it has begun to be torn off the outlet metal pipe. That is, the thread on the union coupling was torn off, and I don’t want to buy a new hose. Russian artisans do this:

A section of a rectangular pipe is taken, in my opinion, 45x25, the “CLIP” grip is carefully and thoughtfully cut out of it. With slots for the hose itself and for the pipe. I think it looks better in a photo. I repeat - if you don’t want to buy a new hose at all.

The design of the product, of course, is not a museum one, but it works properly. The connection may slightly dig, but this is not critical.

There is an equipment base in the tourist club Korbita. There is a well and a Karcher pressure washer. For three years the whole system worked without failures. And now, the Karcher hose broke. Many questions immediately arose. Where to buy a new hose? Where to run if Karcher is urgently needed?

We found out everything and share our experience! First, the Karcher hose is a high pressure hose and can be repaired. Secondly, Karcher high-pressure hoses can be repaired with your own hands, or you can do it in a specialized organization.

Do-it-yourself Karcher hose repair technology is very simple. First, cut the hose along the edges of the gap. Then we make the cuts even - either with special scissors, or with a machine, or with a cutting tool.

After that, we go to a special store for a fitting (a connecting tube along the inner diameter of the hose) and special power clamps. Ideally, put a pair of clamps on each side. Attention, simple clamps will not work!

Such a do-it-yourself hose repair has disadvantages. If the hose is used in the washing area, then the repair unit (clamps) will constantly cling to something, this is inconvenient.

Another minus. If you don’t have a fitting and a power clamp in your garage (in your warehouse), you still spend time looking for and buying a fitting of the desired diameter and clamps.

But there are also pluses. Such a repair of Karcher high pressure hoses will not be expensive. Especially if you need to lengthen the hose or make a few repair connections.

If you have little free time, you should turn to professionals. Pros . Repair the Karcher hose on site in 10 minutes. Repair carefully, the repair unit will not interfere with the work with the sink. Repaired on professional equipment and reliably.

Minuses . The cost of repair is 500-800 rubles for each node. That is, at a market value of a non-original, but acceptable in quality, Karcher hose of 2000-2500 rubles (autumn 2018), it makes sense to make repairs if you have a relatively new hose and no more than 2 damage. In other cases, it is worth thinking about a new hose.

We have compiled a list of organizations in major cities of the Central Federal District where you can repair the Karcher hose:

If your city is not listed, try clicking here.

At least in a nutshell, but we need to talk about the reasons for the repair. In our case, the reason is this - the sink itself “shudders” at startup. The hose coming from the sink gradually rubbed against a sharp corner. But there may be other reasons - poor-quality hose material, mismatch of the operating pressure of the hose with the washing pressure, obsolescence of the hose, and others. Of course, all these reasons must be eliminated.

That's all! Keep your tool in good working order, keep enjoying your hands! Have a good day!

Repairing a high-pressure hose at Karcher is an almost hopeless business. If it is damaged in a straight section, crushed, chopped, and so on, then finding a double-sided Christmas tree branch pipe and compressing it at home on a hose is very problematic. You can do without buying a new (very expensive) hose only if it has begun to be torn off the outlet metal pipe. That is, the thread on the union coupling was torn off, and I don’t want to buy a new hose. Russian artisans do this:

The design of the product, of course, is not a museum one, but it works properly. The connection may slightly dig, but this is not critical.

On karcher sinks, depending on the year of manufacture, there were two fastenings of a high-pressure hose, this is a hose that goes from the washer to the washing gun.

The threaded connection is used on later production sinks and is replaced by a quick coupling.
To unscrew the hose from the sink, if you have just used the sink, release the water pressure in the hose by pressing the gun button, and unscrew the hose from the sink in a counterclockwise direction.
Often, the original threads are plastic inside and this caused problems during prolonged use, the high pressure hoses sold in our store have brass threads. hose link.

The quick coupling replaces the threaded connection.

​
If you have just used the washer, pull the trigger on the washer gun and relieve the water pressure inside the hose.
Grasp the hose at the entrance to the sink and press with your finger or the second hand on the plastic black circle towards the sink, pull the hose away from the sink.

It is advisable to periodically, once or twice a season, disconnect the hose from the washer and from the gun, clean and lubricate the thread or quick connector.

Do-it-yourself karcher high-pressure hose repair. Car washes and car services installation, repair, service of cleaning equipment of devices, hoses

Washers "Karcher" are different in themselves, different outlet pressure, different sleeves (hoses).

A hose rupture can be anywhere, the most “unpleasant” one can be considered a gust somewhere in the middle, such a repair is difficult.

As an option for a Karcher household sink, use a herringbone fitting

And compress it with clamps, but it is better to take reinforced steel clamps.

We buy here such a bolt with a flat head for a screwdriver.

We drill a hole in it to the full depth, as a result we have a tube with an external (external) thread.

You can buy these bushings with internal threads for the bolt,

You can simply cut threads in steel tubes.

The inner thread of the sleeve corresponds to the outer thread of the bolt (the pitch is the same).

Cut off the problem area.

We insert the bushings into the hose tightly.

We take a thick-walled copper pipe and cut it in length, slightly more than the length of the bolt.

We twist the bolt (drilled) into one sleeve, then we wind the second part of the hose with the sleeve.

We push the copper pipe onto the connection and slightly clamp it in a vice.

If someone does not understand, here is a video, only in the video a person repairs a sleeve from improvised materials.

Pay attention to how he drills the bolt, the drill is clamped in a vise, and the bolt is in the screwdriver.

Instead of a vibrating cutter, you can use a grinder.

At the finish we get a “picture”, the thread does not allow the hose to break, and the outer tube does not allow the sleeve to swell.

In my opinion, the whole “genius” of such a solution is in the simplicity of execution, and the tools used are ordinary (many have them) drill, screwdriver, tap, grinder.

High pressure hose repair - implies pressing a torn high-pressure hose at the ends (pressing in a new end fitting), pressing the hose at a break approximately “in the middle” - inserting a special repair fitting and its subsequent pressing, pressing the fitting for the required high pressure apparatus.

Our service center for high pressure hoses also offers you such services as:

• pressing high-pressure hoses of the required length (from 1 meter or more)
• pressing with the required fitting (for example: M22x1.5 nut; 3/8″ nut or fitting; 1/2″ nut or fitting; 1/4″ nut or fitting - check the availability of the fitting you need)
• production of a high-pressure hose for the most popular high-pressure cleaners: Karcher (Karcher) with an 8 mm fitting (a new mount for Karcher mini-washers since 2008), 10 mm, 11 mm and a M22x1.5 union nut
• pressing a high-pressure hose for connecting ceiling consoles (rods) both from the device to the console, and a hose from the console to the high-pressure gun
• production of hoses for high pressure pulling through the washing box (car wash)

Please note that we can offer you a replacement for the original plastic hose (as a rule, household mini-sinks are completed) with a more durable and professional high-pressure hose. If you just want to repair the old hose - contact us. Also, our sleeves are made or repaired from various high-pressure apparatuses: in addition to Karcher, also Kranzle, Portotecnica, Faip, Bosch, Lavor, IPC, Poseidon, WAP, Alto, etc.

If you have a household high-pressure apparatus that needs to be repaired, and we do not have the required fitting (household car washes), we offer the following repair option: we UNPRESSURE your original high-pressure hose, that is, remove the tips from the original hose, and subsequently press them into a new high-pressure hose of the required length, the cost of such a repair service varies depending on the complexity of the hose.
More and more new high-pressure apparatuses are being imported into our country, and as a rule, trouble is with the service center. But do not worry - we will help you: we will repair your high pressure hose or extend it to a longer length.
Also, high-pressure hoses are used when installing (pulling) a high-pressure line on a future or already operating car wash of the required length for their subsequent installation on walls and ceilings. etc. In this embodiment, a high-pressure hose is used as an analogue of high-pressure pipes. Connect from machine to gun, console or simply distribute high water pressure. We can also repair an already installed high pressure hose.

Popular with homeowners. With this compact device, you can clean almost any surface from dirt. In addition, the use of a mini-sink allows you to reduce water costs. Therefore, such devices are often used in car washes and cleaning companies.

It is quite logical that the continuous operation of the mini-wash can lead to equipment failure. The most common problem should be considered a breakdown of the high pressure hose that provides water supply under pressure. Below are solutions for some common problems.

Diagnostics, maintenance (TO), minor repairs is 2-3 days.
Repair average 5-7 days
The repair is complex with a complete overhaul of 7-15 days.

Repair with bulkhead - 30 days.
Maintenance (TO) of all types of equipment - 20 days.
All adjustments: carburetors, cables, belt and chain drives - 10 days.

Departure for diagnostics, maintenance and minor repairs or equipment collection is possible. The cost is calculated based on the amount of work and distance.

Quite often, the cause of a hose breakdown lies in the damage to the flange, that is, the fastener that connects the hose to the minisink. In this case, it is necessary to purchase a flange that is suitable for its parameters and install it in the base of the hose. The installation procedure may require the use of pliers and a hammer, with which the fasteners are adjusted to the diameter of the hose.

Karcher hoses are often subjected to mechanical stress, which leads to the appearance of holes, tears and cuts in them. It would seem that in any other case, an overlay glued at the place where the gap appeared would be an ideal solution to this problem.

However, the pressure inside such a hose is so great that no adhesive will be able to hold the patch. The ideal option in this case is to replace this part. If, for one reason or another, a spare hose cannot be obtained, you can resort to using clamps and a connector.

The connector is an elongated piece of metal that is attached at the point of rupture.To hold it, clamps are used that “tighten” the connector, preventing it from moving.

Karcher car wash repair (connector tube replacement)

In this article, we will look at how to do a do-it-yourself car wash repair and how to get to the outlet at the Karcher sink and replace it.

First you need to unscrew the screws (for a Phillips screwdriver) that are located on top of the handle

Then unscrew the screws securing the back cover

Now lay the sink and remove the top cover

Access to the internal components is opened and we can already remove the connector

Removing the metal bracket

Raise the pump and pull out the tube. We give a new spare part and install in the reverse order. Carefully remove the rubber sealing ring and rearrange it in a new connector. Next, install back and insert the fixing bracket.

Good day! They gave away a STIHL RE 108 sink for free. We need to change the high pressure hose. I can’t unscrew the nut near the pump with a gas wrench ((I’m afraid I won’t tear it off. How can I do it? I also have a native hose that costs 1000 UAH on some site. Maybe it’s cheaper from some other model? Thank you!

Cleaning a garage, a warehouse, cleaning a car, and even your own summer cottage, become simple and easy if you purchase special equipment for this - a high-pressure washer. It is difficult to imagine a car service without a car wash; it can also be used to wash concrete mixers, pipes and other equipment well. Everyone knows how convenient high pressure washers are for farmers - cleaning stables and agricultural machinery turns into a quick procedure that even a beginner can master.

The cost of the fixture varies from 4,000 to 20,000 rubles, depending on the material used in the manufacture of the body and other important parts of the instrument. Experts note the excellent quality of brass products, the pistons of which are made of cermet. The right choice of pressure washer is not complete without due attention to the included nozzles, it is good if this includes the following components:

• cutters designed to work with dirt;
• sandblasting and pumping tip;
• various brushes;
• corner nozzles.

In order for the high pressure washer to show a long service life, use a water filter that will protect the internal structure of the hoses from contaminated fluid flow. At the end of the work, each time you need to drain the unused water from the equipment and release the pressure.

Such preventive measures will protect the equipment from sudden breakdown, but this does not mean at all that there will not be a situation when a full repair of the device is required. You can make it yourself, for this you just need to know some of the subtleties of modifying the instance.

The main malfunction, which may appear after several years of active operation of the equipment, is the bearing, which serves as a support for the swash plate that presses the valve.

How the breakdown manifests itself in Karcher:

1. The high-pressure washer works jerkily, the engine regularly refuses to start, a knock is heard from inside the structure.
2. The engine does not work at all, it hums very strongly and heats up, it literally plows with heat.

In this case, do-it-yourself repair of the Karcher sink bearing is the following sequence of manipulations:

1. Remove the hose from the gun.
2. Carefully disassemble the housing base, remove the electric motor equipped with the cylinder head.
3. Unscrew 6 self-tapping screws from the electric motor, the heads of which are made in the form of stars.
4. Open the block where the switch is located and get rid of the capacitor along with the 2 power terminals coming from the switch. Put the spring in a secluded place, if you lose it, it will be almost impossible to find exactly the same part in stores.
5. Using some kind of vertical stand, firmly fix it on the floor.
6. Place the pressure washer on this support with the motor facing down.
7. Carefully unscrew the 4 bolts by 13.
8. Oil will begin to pour out of the equipment, be careful.
9. Drain the oil into a container and set aside the rubber seal.
10. Inspect the condition of the clip with balls.
11. Using a screwdriver that allows you to remove the star-shaped fasteners, disconnect the bolt located in the center. To do this, clamp the shaft from the other side with a gas wrench.
12. Replace the bearing, which is now visible.
13. The assembly of the equipment is carried out in the reverse order.
14. Do not forget to fill the inside of the Karcher high pressure washer with new oil.

Video instructions for eliminating possible breakdowns of Karcher equipment can be viewed below:

Before determining the method of how to repair a sink with your own hands, it is necessary to determine the exact cause of the breakdown. The list of major faults includes:

1. Reducing the supply pressure. There can be no question of any performance in this case, the time of the procedure immediately increases. Repair consists in eliminating damage to the seals. Why do seals break? Long-term use and low-quality impurities, substances in the water used spoil and quickly wear out the material. There is nothing you can do here, except to replace the oil seals with your own hands.
2. One of the valves is faulty. It is unlikely that you will be able to do it yourself, repair is most likely impossible without diagnostics with special equipment in a service center.

So that you do not have to deal with the listed malfunctions in the operation of the "Calm" and "Champion" sinks, you should follow the important rules and requirements:

1. Pay attention to the quality of the water used, the liquid must not be contaminated.
2. Repair of a pressure washer will not be necessary if you make it a rule to carry out regular preventive maintenance of the product.
3. Focus on proper voltage and change oil on time

Repairing a sink with your own hands is, of course, a useful and developing business, but it’s better to never encounter this need. The right choice of a quality installation will help to avoid unexpected and premature breakdowns. On this issue, experts give several practical recommendations:

1. "Champion" will appeal to those who appreciate the reliability and ease of use of technology.
2. Stihl is a surprisingly compact pressure washer, no less durable than the first copy.
3. "Hooter" is universal, it makes it possible to use it in different jobs, however, experienced customers already know that the Chinese "Hooter" often requires do-it-yourself repairs.

Finally, it is worth noting that Interskol is highly productive, but, despite this, it costs moderately, which is very pleasing to people who are short of money or who do not want to spend a lot on high-pressure washing.

If the hose is torn off the flange, then you need to cut off the damaged section of the hose evenly, to the point where there are no extensions, cracks and undamaged cord.

Next, purchase the necessary flange and install it - fortunately, a large number of them are sold in auto stores and there is also a choice. The flange is inserted into the hose and simply crimped well with the help of a stop in the vise jaws and hammer blows from the third upper side.

If the damage is somewhere along the length of the hose, for example, a cut, a rupture, or something else, then we do exactly the same as in the first case, cut the hose and cut it to a whole, but here a connector of the desired diameter and a pair of clamps will help - Just buy clamps not cheap, but good ones like those in the photo!

It is very doubtful to repair Karcher in the middle with herringbones. What collars hold 140 eyes? And more? Didn't see those.

Threaded connection only. Press nipple and “father-mother”.

All these collars fly like birds. - 3 years ago

In a vice - do not compress. And a hammer won't help. Everything will be clumsy and uneven. That is to say, unsafe.

Repairing a high-pressure hose at Karcher is almost a lost cause. If it is damaged in a straight section, crushed, chopped, and so on, then finding a double-sided Christmas tree branch pipe and compressing it at home on a hose is very problematic. You can do without buying a new (very expensive) hose only if it has begun to be torn off the outlet metal pipe. That is, the thread on the union coupling was torn off, and I don’t want to buy a new hose. Russian artisans do this:

A section of a rectangular pipe is taken, in my opinion, 45x25, the “CLIP” grip is carefully and thoughtfully cut out of it. With slots for the hose itself and for the pipe. I think it looks better in a photo. I repeat - if you don’t want to buy a new hose at all.

The design of the product, of course, is not a museum one, but it works properly. The connection may slightly dig, but this is not critical.

Do-it-yourself Karcher repair. Do-it-yourself repair of a high-pressure hose, high-pressure car wash, mini-wash, foam nozzle, Karcher pump

With regular use of a high-pressure washer, high-quality maintenance of the device in a service center is required. In order to save money, many users repair Karcher with their own hands. It is not recommended to carry out self-cleaning and replacement of parts before the end of the warranty period, which will affect the denial of further service.

For trouble-free operation of the device, regular replacement of oil, seals and cuff on the pump (high pressure pump) is required. In the event of interruptions in water pressure or improper storage / use of the device, an urgent do-it-yourself repair of Karcher may be required. What parts fail?

Pump, motor and pressure sensor. Electrical part. Nozzle, hose and gun.

The choice of household mini-sinks eliminates the occurrence of difficulties in care, but different models have their own characteristics, which you must first find out from the seller. For example, a car wash nozzle with a lamellar structure will ensure high-quality operation with regular cleaning with a toothpick. Otherwise, the ingress of small particles will cause the unit to stop working.

When purchasing a product, you should clarify the availability of the nearest service centers and the warranty period. If such issues are overlooked, the breakdown of the device will lead to unnecessary problems. If you decide to repair the Karcher with your own hands, the right step is to study the instructions in detail.

According to the manufacturer and employees of car washes, the main reasons for the breakdown of the device are poor water quality and lack of after-sales service. To increase the service life of the unit, it is necessary to comply with the basic requirements:

Install a filtering device for coarse and fine water cleaning at the inlet to the AED. Control the flow of the required volume of liquid according to the technical indicators of the device.For example, if the fluid flow is 15 l / min., And the water supply allows you to get 13 liters, after 2 months you may need to immediately repair the Karcher with your own hands (or at a service center). Water pipe diameter should be 3/4 inch per unit. Factory nozzles and accessories are subject to self-replacement.

With regular preventive maintenance, you can eliminate the occurrence of unforeseen circumstances that will entail the replacement of expensive parts.

Check the condition and regularly change the oil in the pump plunger drive device. According to the manufacturer, the first oil change should be carried out after 50 hours of using the device, the subsequent service - after 350-550 hours. With average throughput indicators of the washing area, it is enough to carry out treatment once every 3 months. Monitoring the condition of the pump for a good flow of liquid, external application of oil, as well as minor repairs to the Karcher car wash with your own hands (changing filters, tightening bolts) will extend the life of the device. For AED with heating, it is obligatory to prevent the boiler - cleaning the fuel filter (removing scale on the inner walls of the heat exchanger and external plaque).

Repair is required if there is a decrease in pump performance and a decrease in operating pressure. This is caused by fluid leaking through the plunger seals. Wear of oil seals is produced naturally or when exposed to abrasive elements. At high pressure, small scratches will affect the leakage of fluid.

The first signal of a malfunction is a small puddle formed at the place where the hose runs. To resolve the issue, you can make a simple, but painstaking repair of the Karcher car wash with your own hands. It is enough to change the seals (seals). More difficulties will cause the installation of a new drive, housing elements, seals, etc.

The suction channel is formed by housing elements that place a flat filter between them. The efficiency of the device depends on its condition. The formation of defects in the fit of the surfaces of body parts leads to a decrease in the main characteristics of the device. With low suction power while working with a hose and nozzles, repairing a Karcher high-pressure washer with your own hands requires the preparation of a soft material to clean all surfaces and ribs of body parts. Damaged items must be replaced.

If the device is equipped with the Total Stop system (switching off the pumping system when there is no pressure on the gun trigger), leaks will lead to involuntary switching on - the automatic device perceives a decrease in pressure as a “start” command, the device rattles.

The deterioration of the bypass or bypass valve, the rubber seal (ring) of the pressure sensor and the failure of the hose affect the performance decrease or shutdown of the AED. This is accompanied by a low level of pressure of the gun, a decrease in the density and washing characteristics of the jet.

If the device does not maintain the set pressure level, the pump works intermittently and the water is supplied in fragments, repairing the Karcher high-pressure washer with your own hands will not be too difficult. It is enough to unscrew the bolts with a screwdriver and remove the housing, get the motor with the pump and separate the engine from it. The pump must be directed upwards, otherwise oil will leak from the piston drive.

The valves are removed from the piston (the use of sharp objects is excluded, which can damage the surface), the pump is disassembled into 2 parts. The valves are removed again.

This is how the cause of the failure of the device is found out. It could be scaling or clogging. All parts in the inside of the pump are cleaned and wiped with felt. Then the structure is assembled in the reverse order.

Do-it-yourself repair of the Karcher high-pressure hose consists in crimping the damaged element at the ends or along the entire length.If the hose is torn off the flange, the unusable part should be cut evenly to an area where there are no deformations. The required flange is selected and placed on the hose. The first must be inserted into the second and compressed in a vice. Hammer strikes from above.

If a cut is formed along the length of the sleeve, similar work is done. The hose is cut and removed to an undamaged section. A connector of a given diameter and two clamps are inserted. They are put on the hose, the connector is inserted, tightly crimped with clamps. If cracks form along the entire length of the sleeve, do-it-yourself repair of the Karcher high-pressure hose is not possible. A complete replacement of the product is required - it is better to entrust this to the masters of the service center.

If the foam nozzle stops producing thick foam, is used for a long time or is not washed with clean water after use, the mesh in the form of a shaft becomes clogged with dried “chemistry”.

To clean the foam tablet, it is necessary to perform a number of operations:

Disconnect the tank from the main frother. The arrow indicates the location of the pin holding the plastic tip of the tablet on the brass element. The pin should be knocked out. If you decide to repair the Karcher foam nozzle with your own hands, you can use an awl or a thin screwdriver. After removing the plastic tip, you will see two petals forming the foam spray angle. The tip with them must be unscrewed. In the inner part of the removed nozzle, steel threads will be visible, taking a rounded shape (in the form of a tablet). They should be removed with an awl. Cleaning of the hardened "chemistry" in the nozzle is carried out with a needle. The assembly of the product is carried out in the reverse order.

Correctly made repair of the Karcher nozzle with your own hands allows you to extend the life of the device and reduce the cost of its maintenance.
