DIY Lavor sink repair

In detail: do-it-yourself repair of the Lavor sink from a real master for the site my.housecope.com.

Greetings, dear readers of my blog! Today I will talk about how to use the device correctly and what malfunctions of a pressure washer can occur when using it in a domestic environment. Today, many car enthusiasts often buy devices for “home” washing their cars. And rightly so, because you don't want to pay extra money for such work, which you could do yourself! Moreover, it should be noted that the purchase of such a device does not at all limit you in its application only in relation to the car... The functionality of the device allows you to use it for various household purposes, so such a device will be a very useful accessory in everyday life.

In order for the device to serve as long as possible, you will have to observe all the points of careful operation, which are indicated in the instructions for use. Moreover, when using such a sink, the following rules must be observed:

Now it's time to tell you about the repair of pressure washers. Even with proper operation, certain breakdowns occur, which in any case need to be eliminated. This can be due to various reasons. In general, we will consider the main malfunctions and methods for their elimination.

Decrease in pressure. This is one of the most common problems that prevents you from getting the most out of your washer. In this case, productivity drops, which increases the process time. Most often this happens due to damage to the oil seals. These parts can break due to prolonged use or due to the presence of substandard impurities. This breakdown must be taken seriously and the part replaced immediately. Otherwise it can lead to more serious problems, so it is best to fix it right away. Often you can change them with your own hands, since there is nothing complicated about it.

Damage to one of the valves can also result in loss of performance. In this case, you need to delve into the reason in more detail. In most cases, it is best to contact service. If the device does not turn on, then it is highly undesirable to try to make it yourself (you should also contact the service center).

In order to prevent such damage, be guided by the following provisions.

Carefully monitor the quality of the water used and avoid clogging.
Install filters. With their help, you can extend the service life several times.
Conduct prevention. Inspect it every month to avoid unexpected breakdowns.
Watch the voltage and change the oil in time! Then there will be no problem.

Nowadays, many models of car washes are presented on the automotive market. Each of them differs in its features and cost... I have studied this issue more deeply and have compiled a small list of the most, in my opinion, quality manufacturers.

"Champion". Very reliable and easy to use.
"Calm". Very compact and robust.
Hooter. Versatile enough as it is ideal for any job.
Interskol. It has high performance and reasonable price.

On this, dear friends, I say goodbye to you! Don't forget to read the updates and share the blog with your friends!

A gun dripped from the Lavor Phantom 19 sink. I unrolled it, inside everything is almost disgraceful: the hose from the sink enters the valve in the L-shaped plastic tube.
The vertical part of the tube has leaked out - water splashes out of it through the micro-slots.
I tried to seal the cracks in different ways: I poured the “moment” with glue, melted the electrical tape, wrapped it with fom-tape and “upset” with a technical hairdryer, smoothed the plastic in the place of the cracks with a soldering iron, and covered it up with cold welding.
None of this helped: the water still makes its way through the micro slits that are not visible to the eye.

How can the plastic tube be pressurized?

ps The new gun is comparable in price to the sink and its purchase is not economically justified.

From the author: Hello, friends! The development and implementation of innovative technologies in almost all industries contributes to the emergence of more and more devices, materials, services that greatly facilitate our life and everyday life. The car service sector is also not bypassed; for this, high pressure washers are successfully used.

Today we will talk not only about the repair technology, but also tell you how to use this device correctly so that it will serve you for a long time and become an indispensable assistant in household chores!

Before proceeding to consider the types of malfunctions and repair methods, it is necessary to outline a number of rules that will significantly increase the service life of your device, as well as avoid elementary breakdowns.

The most important thing is to carefully study the operating manual before using the device, it contains basic tips for the careful use of the device. In addition to the standard requirements, the following should be highlighted:

Decrease in pressure in the apparatus. When this problem occurs, the machine may not be able to take full advantage of all the functions. This is one of the most common problems with these devices. As a result, productivity drops dramatically, leading to a significant increase in cleaning time.Most often, the reason for this is failed oil seals. Their breakdown can be caused both by the duration of their use without replacement, and by the presence of harmful impurities. This problem must be solved immediately and the defective part replaced. After all, this can lead to even more serious problems. Replacing parts is not a complicated operation, so you can do it yourself.Loss of performance can also result in the failure of one of the valves. This breakdown is much more complicated, and it is difficult for a non-specialist to fix it, so in this case it is better to contact a service center for such equipment.So, the sink began to work intermittently and the pressure dropped significantly. How to repair? In this case, we recommend doing the following work.The sequence of disassembling the apparatus is as follows.

We dismantle the casing from the sink disconnected from the network.

We turn the device upside down and remove the plastic pipe, usually it is fixed on three bolts, so here we need a hex wrench.

We remove the valve using pliers.

We inspect, wipe and disassemble for components.

We lubricate the parts and assemble them in reverse order. Do not forget to check the strainer, it is located on the pipe. It may be torn, and therefore contamination ends up on the valve. In this case, it must be replaced.

In order for your sink to serve you much longer without breakdowns, we advise you to adhere to the following operating rules:

monitor the quality of the water used, do not use dirty water, with impurities;
use filters, this will extend the service life of the device several times;
preventive monthly inspection will help to avoid unexpected breakdowns;
do not disregard the supply voltage and change the oil in a timely manner.

Today on the market of goods for car maintenance there is a wide selection of pressure washers, which differ in their functionality, quality and, of course, cost.Of the variety of manufacturers of such devices, the following, in our opinion, are the most worthy and high-quality ones:

"Champion" - is distinguished by its reliability and ease of use;

"Karcher" - a high-quality and reliable device, a wonderful and well-organized service anywhere in large cities;

"Calm" - compact and reliable sinks;

"Hooter" is a universal high pressure washer that can be successfully used not only for cars, but also for household work;

Interskol - the unit shows good performance and affordability.

In accordance with current legislation, the Administration disclaims any representations and warranties, the provision of which may otherwise be implied, and disclaims responsibility in relation to the Site, the Content and its use.

Washing a car, cleaning a garage or tidying up a summer cottage - all these works are greatly facilitated by a mini-wash. Some models are quite suitable for flushing pipes or concrete mixers. Unattractive and difficult work like cleaning stables or washing agricultural machinery is greatly simplified with the help of this miracle device. The topic of today's publication is the repair of a pressure washer with your own hands, because any technique tends to fail after a particular period of operation.

In order for the mini-sink to serve as long as possible, it is necessary to follow the not very complicated rules for the safe operation of the device specified in the instructions for use:

Remember to ensure that there is sufficient water in the sink. If this rule is neglected, the pump can quickly fail.
Take care not to bend the hose. Otherwise, the device will fail due to the excess of the water level. It will not be superfluous to make sure that you do not step on the hose or run over it with the wheel of the device.
Choose a mini-sink in such a way that it is equipped with a hose reel. In this case, the working life of the device will be much longer.
Remember to drain the water after you have finished using the appliance. Especially if you have operated your sink at low temperatures. Water, turning into ice, will provoke a breakdown of the device.

Important! It is equally important to release pressure from the pump.

Use your mini-sink very carefully. Water is supplied at high pressure, so even small dents may appear on the surface of the car if used carelessly. Therefore, you do not need to bring the device too close to the surface to be treated.

Important! It is strictly forbidden to point the device at people or animals, as this may cause injury.

If you need to take a short break from work, never leave the device turned on.
Make sure that the water used is free of foreign matter.
Change the oil in time.

These preventive measures will protect the worker and those around him. But this does not mean at all that the sink will work forever. Even with the most careful operation, breakdowns cannot be avoided. Consider the rules for repairing a broken Karcher car wash.

Most often, bearings fail over time, which serve as a support for the washer acting on the valve.

The symptoms of bearing failure are as follows:

Unstable wash operation. In this case, the engine often does not start; a knock is heard inside the device.
It also happens that the engine does not start at all, it gets very hot when turned on.

Do-it-yourself mini-high-pressure washer repair is the following set of manipulations:

Remove the hose from the device together with the “gun”.
Disassemble the case, remove the motor.
Unscrew the 6 self-tapping screws located with an "asterisk" from the motor.
Open the box with the switch, remove the capacitor and power terminals that come from the switch.

Important! Watch carefully so that the details are not lost: it will not be possible to purchase something similar in the store.

Place the sink carefully on a horizontal surface, motor downward.
Prepare a container to drain the oil.
Unscrew the bolts by 13 (there are 4 in total).
Drain the oil into a previously prepared container, put the rubber seal aside.
Unscrew the bolt located in the center, having previously clamped the shaft with a wrench on the other side.
Replace worn bearing.
Assemble the mini-sink in the reverse order, remembering to fill in new oil.

Important! The original oil is difficult to find, so use a suitable analogue.

In addition to bearing failure, the following failures also occur:

Reducing the pressure. The performance of the device decreases, the time for performing washing procedures increases dramatically. The cause of this trouble is damage to the oil seals. Oil seals fail due to prolonged operation of the sink and the presence of impurities in the water. You can solve the problem by replacing the oil seals.
Valve defective. It is hardly possible to make an independent repair, therefore it is much wiser to contact a service center.

The essence of the repair is to flush the valve and its seat where it is inserted. To get to it you need:

- unscrew the protective external elements of the car wash

- dismantle the water intake pipe

- pull out the bypass valve with pliers

- we clean it from dirt and lubricate

- collect in reverse order

Usually, all repairs can take about an hour.

The Karcher 586 M plus model, after 7 years of trouble-free operation, once did not turn on at all.
But it was used carefully, with an additional filter for water purification.
She worked from time to time in her own warm garage, to wash her personal car, sometimes her friends' peppers, sometimes she was taken to the dacha to wash furniture.
Officially registered in the garage society, for the use of technical water from the tie-in on a quarterly basis
a certain amount is paid.

My 5xxx and higher series differs from the downstream ones in that the declared pump is made of an aluminum alloy-silumin, which, in theory, gives a great resource.
Repair in the service did not inspire due to the lack of nearby authorized Karcher centers,
and reading information on the Internet did not add optimism about the prices for repairs.
It turns out better to buy a new sink, preferably the same as mine, or 520 M plus with a similar pump.
As they wear out, you can throw over compatible parts and thus extend the life of the sink.

I believed that the reason is the wear of the parts, the period is already relatively long for the device.
But the first thought is that something is wrong with the electrician, the contacts are likely to oxidize, the conductive track has worn off at the switch.
Disassembly and visual inspection of electrical contacts remained.
Along the way, at the same time, it was decided to tear the pump apart, rinse and lubricate all the parts.

In the internet found technical documentation with a diagram.
The closest model turned out to be 593 M, it differs from mine only in two shampoo tanks.
... 33969.html

It is easy to figure out what is crammed in the motor and how

In fact, the reason later turned out was commonplace, it soured from deposits and the bypass valve jammed.
The switch, when turning the toggle switch, pressed the rod with its lever and activated the motor.
And all the electrical contacts turned out to be in order, as well as the capacitor checked by the tester.
I post pictures, everything is clearly visible there.

Karcher disassembled:

Before disassembling.

The upper part is removed.

Pistons.

Eccentric drive shaft.

Upper half.

Here is the jammed stock.

Side view.

Disassembled.

All rubber bands are in good condition.

Valve.

Electrical switch box.

The capacitor is working.

Pusher rod.

The pump parts were placed in warm water with citric acid, then thoroughly rinsed and dried.
The bypass valve was too tough for me, I could not make it out :(
According to the scheme, two pins must be pulled out there, unscrew the plastic cap with a spout for supplying water to the shampoo, squeeze out the tongue and remove everything assembled.
I decided to just pour WD-40 into the inner valve holes abundantly, let it rest for 2 days.
After I developed the valve with pliers, I pulled and rotated the tongue by the nose :)

Since there is no original lubricant from Karcher, I picked up analogues for it.
The assembly was carried out with the lubrication of all liners and sealing rubber bands with Litol-24.
The joints of the body parts are lubricated with Abro sealant.
In the motor, where the eccentric washer pushes the valve, it is advised to fill the motor semi-synthetic
oil, up to half the height of the washer.
Of course, after removing the old grease.
I didn’t do it because there was enough factory lubricant so far, I picked it up from the walls and coated the springs and rods.

Everything was put back together and worked like new.

Each owner of a mini-wash sooner or later faces the issue of maintenance or repair of the device - the reason can be both natural wear and tear of components and mechanisms, and non-observance of operating rules. In any case, the breakdown can overtake at the most inopportune moment, and then you will have to wait long enough for the masters to find the cause of the malfunction and eliminate it. In order to facilitate their work and bring the device back into action, we will provide you with a list of the most common breakdowns and their main causes - this will help you diagnose the malfunction on your own and significantly reduce the time required to diagnose the equipment.

The hose broke. This happens quite often and mainly due to oversight - it is enough just to take the hose "on the kink" or step on it, and the reinforced amplifier inside will crack.
Tightness is lost and pressure drops rapidly. It may well be that hard water with a large amount of impurities is to blame. Salts and other compounds that give sediment build up on the inner surfaces of the pressure washer in the form of a deposit and come off over time, causing mechanical damage to the pump.
Broken springs, valve, thrust washer or ceramic plungers. The first possible cause may be air leaks from a hose or plumbing. Under the action of the pump, air bubbles explode, and there are so many of these explosions that the sink begins to literally "pound", which damages its most vulnerable parts. The second reason may be a too rigid connection to the water supply - a solid hose does not suppress surges in the speed of the liquid at the time it is supplied to the device, and the entire water hammer (a sharp change in pressure) falls on the device itself, because of which some of its elements can simply "break".The third reason may be excessive outlet water pressure (for example, the norm for your device is 1-2 bar, but it has accelerated to 18 bar), which again can damage the internal parts.
Water "siphonite" through the stuffing box seals. Of course, this may be due to the natural wear of the oil seals, but if the device is new, then perhaps there were too many abrasive particles in the water. But even the smallest scratch can quickly develop into a large leak.
The recoil of the pistol when turned on has significantly decreased, and the water jet has become weaker. In this case, focus on the bypass valves, pressure regulator rubber rings and hose. Most likely, they are worn out and require immediate replacement.
The sink cannot reach full power when switched on. First of all, you need to clean the water filters (you can do this yourself) and check the tightness of all connections. Also, it will not be superfluous to bleed air from the device using the method specified in the instructions.
The device shuts down spontaneously after a short operation. Shutdown is triggered by thermal valve actuation, caused by overheating of the engine or too high temperature of the suction water. If the engine is normal and the water is cold, the thermal valve itself is most likely faulty.
The sink does not take water from the container, but it works properly from the water supply. It is very possible that the pump is simply airy, and you just need to remove all the nozzles and release the water until the stream stabilizes. It is also possible that the hose is too soft and shrinks during suction, blocking the path of water. In this case, it is enough to simply replace it with a more rigid one. It may also be that the filter on the inlet is clogged and does not allow water to pass through well - you just need to remove and rinse it.
The outlet pressure drops sharply. Most likely, the debris is to blame for this, since the wear of any parts of the apparatus decreases the pressure gradually, and only the blockage does this practically instantly. Most likely, solid particles and other debris are stuck under one of the discharge valves, in the seat of the check valve, in the injector or in the hose (gun) itself. But it is better not to disassemble the device in search of a problem, but give it to specialists - they will be able to remove even the most difficult mud plug without damage.
The electrician stopped working or there were serious malfunctions in her work. The reason may well be the elementary ingress of water during wear of the sealing gaskets. Moisture causes a short circuit that can burn the contacts, the magnetic starter, capacitors, or even the motor itself.

As you can see, there are a lot of problem situations, and their consequences can be quite deplorable, but now, knowing the main causes of breakdowns, you can notice them in time or even prevent them altogether, provided that you follow all the operating rules. If problems cannot be avoided, do not rush to send the device for recycling or repair it on your own - the services of specialists for the maintenance of mini-washers are not very expensive (much cheaper than buying a new sink instead of an irretrievably damaged old one). In addition, an official guarantee is given for their work, which means that you can be sure that the device will serve you for a long time.

We hope our tips were useful to you!

Sale. Selection. Installation. Rent. Repair. Guarantee. Quality. Reliability.

Car cleanliness is not only an aesthetic indicator, but also protects the product from negative environmental factors. After all, adhered and dried dirt can contain aggressive elements that damage the paintwork. Also, long-term and regular contamination of the body can lead to irreversible damage to the metal, up to perforating corrosion on individual elements.

In this case, regular visits to the car wash or home water procedures save the day.But in the second case, you need to buy a washing device or a car wash should be made with your own hands from improvised means. Prices in stores generally start at 5,000 rubles. The upper threshold may not stop at 20 thousand. Therefore, we will do it ourselves.

The main part of any water supply unit is a pump. For our product, it will need a powerful enough, capable of developing a pressure of at least 150 atmospheres. When choosing a ready-made pump, it is necessary to take into account the materials from which the working units are made.

Preference should be given to products with a high-strength metal or ceramic piston.

In this case, the block head is recommended to be selected from brass or bronze alloys. This design is more durable. Its resource between repairs is quite high. A flow rate of 15 l / min will be sufficient for the pump.

It is advisable to select an electric motor with a voltage of 220 V. Reliable start-up is ensured by an additional capacitor unit. Higher rpm will provide more productivity.

You need to know that a pump that is too high-speed with a high speed can lose power at maximum operating speed and is subject to intense wear.

Consumers of 2-3 kW and rotation up to 2000 rpm are considered optimal.

A do-it-yourself high-pressure washer designed must have the necessary safety elements in the chain to preserve important components. This link is the coupling that connects the pump and the motor.

It is advisable to install a coupling that can compensate for small axial misalignments between the shafts.

It is also possible to install a belt drive with one stage. This gearbox balances the speed and load between the motor and the pump. The gear ratio is selected based on the required output parameters in terms of rotation frequency.

The mini washer must be equipped with a sufficient water tank. A tank is suitable, which can be additionally powered from a permanent source of water: a water tap, a deep-water well, or a small water tower.

It is advisable to install coarse and medium filters at the inlet to the tank. So, unnecessary debris will not get into the pump and will not interfere with the operation of the entire system.

Car shampoo or other approved car cosmetics can be added to the main water tank. The process will be more efficient.

The capacity regulator is usually combined with an auto-unloading valve on the pump, which redirects the unused pressure back to the tank, reducing the load on the pump.

All units are mounted on a frame made of shaped or round curved pipes. Often a pair of wheels are attached to the lower pipes to help transport the unit. Also, stops for fixing and a handle are installed so that the entire structure can be moved.

The appearance of a do-it-yourself car wash

For a high pressure hose, you can use a plastic or rubberized reinforced hose. It is imperative to ensure the tightness of the joints using high-quality clamps or hydraulic sealing.

The structure must be collapsible and maintainable. Therefore, it is advisable to use threaded connections where possible.

Also, in places of contact with water (fittings, valves), low-corrosion alloys must be used: brass and bronze.

Direct water supply is carried out through a gun with a nozzle installed in it. It bears a visual resemblance to a pistol at a gas station. A stream of water is formed only after pressing the button. This method helps to save prepared working fluid with consumable additives. The pistol can simply be bought at any hardware store.

When operating, you must follow a few tips:

periodically it is necessary to inspect the connecting nodes and tighten the threaded connections with a wrench;
filters installed in the device need to be inspected before each connection so that the throughput does not decrease;
the electrical part must be grounded to avoid accidents during operation, for this, a cable with three copper conductors is used, and the plug must have a grounding terminal;
during the washing process, it is not necessary to fix the jet at one point on the machine body for a long time, so as not to damage the paintwork with a strong pressure.

The device for high-quality contactless washing is called a foam generator. With its help, you can completely envelop the machine with small bubbles of washing suspension and carry out a high-quality cleaning of the surface from dust, dirt and adhering small particles.

Foaming process with a home foam generator

A DIY foam generator can be made even in the garage. You need to be patient and prepare all the nodes and elements.

The device performs two main functions during the car wash process:

formation of fine-cellular foam from prepared reagents;
uniform application of foam to the desired surface of the vehicle.

To carry out this process, a stream of water mixed with car cosmetics (shampoo or other specialized preparations) is sprayed with an air stream passing through the installed channels, and together they form a coarse foam.

The mixture is then passed through a foaming tablet block. Now this mass can be applied to the surface.

The flow control plates provide a fine spray jet to distribute the working foam to all the unevenness of the exterior of the body.

The quality of work of a professional wash using a foam generator can be higher than when using a device made by yourself. For this, there are several criteria that determine the final result.

The main parameter is the size of the formed foam. An important characteristic is the homogeneous structure and the minimum bubble diameter.

When using professional washes, specialized industrial shampoos are used.

Also, professional equipment allows you to pump significantly more fluid pressure than that which can be achieved in a garage. This reduces the consumption of cleaning materials.

But with all these factors, the result of self-cleaning turns out to be quite worthy, especially since the final price for one session speaks in favor of a home-made device.

The manufacture of a foam generator will require the creators to stock up on a set of keys, a grinder, a pre-purchased repair kit with spare parts for a professional installation, consisting of a nozzle, a pistol, a compressor, and a flushing hose.

In addition to the listed elements, it is necessary to take an inch pipe with a length of about 70 cm. You will need to make a filter from it. To do this, fill the cavity with pieces of fishing line. It is advisable to use it of different diameters, so the foam will form more efficiently.

After stuffing, you will need to install metal filters on both sides to avoid pieces of fishing line getting into the container with shampoo.

The principle of operation of the foam generator

Further, threaded plugs are placed on both ends of the pipe. Now a T-junction is screwed to one of the plugs. A compressor is screwed to such a transition, and a hose from a liquid reservoir is screwed onto the second thread. The free end of the line will be the foam outlet. A hose for spraying ready-made foam is attached to it through a fitting.

You need to know that the quality of the formed foam depends on the quality of the stuffing in the tube with the fishing line.

You can achieve the desired result by changing the packing in the tube with line. It is also allowed to empirically select the required length of such a pipe and the texture of the fishing line.
