In detail: high pressure washer calm 118 DIY repair from a real master for the site my.housecope.com.
Cleaning the garage, warehouse, car cleaning, and even your own summer cottage, becomes simple and easy if you purchase special equipment for this - a 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 very well how convenient pressure washers are for farmers - cleaning of stables and agricultural machinery turns into a quick procedure that even a beginner can master.
The cost of the device varies from 4,000 to 20,000 rubles, depending on the material used in the production of the body and other important parts of the tool. Experts note the excellent quality of brass products, the pistons of which are made of cermet. The correct choice of a pressure washer is not complete without due attention directed to the supplied attachments, it is good if the following components are included:
cutters designed for working with dirt;
sandblasting and suction tip;
a variety of brushes;
corner nozzles.
To ensure a long service life of your pressure washer, use a water filter to protect the inner hose structure from contaminated fluid flow. At the end of each work, unused water must be drained from the equipment and pressure must be relieved.
Such preventive measures will save the equipment from sudden breakdown, but this does not mean at all that a situation will not come when a full repair of the device is required. You can do it yourself, for this you just need to know some of the subtleties of modifying the instance.
The main malfunction that can manifest itself after several years of active operation of the equipment is the bearing, which serves as a support for the swash plate pressing on the valve.
How does a breakdown manifest itself in Karcher:
The pressure washer runs jerkily, the engine regularly refuses to start, and a knock is heard from inside the structure.
The engine does not work at all, hums very much and heats up, literally plows with heat.
In this case, do-it-yourself Karcher sink bearing repair is the following sequence of manipulations:
Remove the hose with the gun.
Carefully disassemble the housing base, take out the electric motor equipped with the cylinder head.
Unscrew 6 self-tapping screws from the electric motor, the caps of which are made in the form of stars.
Open the box where the breaker is located and dispose of the capacitor along with the 2 power terminals coming from the breaker. Put the spring in a secluded place, if you lose it, it will be almost impossible to find the exact same part in stores.
Using a vertical stand, fix it firmly to the floor.
Place the pressure washer on this support with the electric motor pointing downwards.
Unscrew the 4 screws carefully by 13.
Oil will start to spill from the equipment, be careful.
Drain the oil into a container and set aside the rubber seal.
Inspect the condition of the clip with balls.
Armed with a screwdriver that allows you to remove the sprocket-head mounts, remove the center bolt. To do this, clamp the shaft on the other side using a gas wrench.
Replace the bearing that is now visible.
The assembly of the equipment is carried out in the reverse order.
Do not forget to add new oil to the inside of the Karcher pressure washer.

Before determining the method of how to repair the sink with your own hands, you need to determine the exact cause of the breakdown. The list of main faults includes:
Reducing the pressure supply. In this case, there can be no question of any performance, the time of the procedure immediately increases. Repair consists in eliminating damage to the oil seals. Why do the oil seals break? Long-term use and low-quality impurities, substances in the water used spoil and quickly wear out the material. Nothing can be done here, except how to replace the oil seals with your own hands.
One of the valves is defective. It is unlikely that you will be able to do it yourself, repair is most likely impossible without diagnostics with special equipment in the service center.
So that you do not have to face the listed malfunctions in the operation of the Shtil and Champion sinks, you should adhere to important rules and requirements:
Pay attention to the quality of the water used, the liquid must not be contaminated.
Repair of the pressure washer is not necessary if you make it a rule to carry out regular preventive maintenance of the product.
Pay attention to proper voltage and change oil on time
Do-it-yourself sink repair is, of course, a useful and developmental business, but it's better to never face this need. The correct choice of a high-quality installation will help to avoid unexpected and premature breakdowns. On this issue, experts give several practical recommendations:
"Champion" will appeal to those who appreciate the reliability and ease of use of technology.
"Calm" is a surprisingly compact high-pressure washer, no less durable than the first instance.
"Hooter" is universal, it makes it possible to use it in different jobs, but experienced clients already know that the Chinese "Hooter" often requires repair with their own hands.
Finally, it is worth noting that Interskol is highly productive, but despite this, it costs moderately, which is very pleasing for people who are strapped for funds or do not want to spend a lot on a pressure washer.
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.

Any household high-pressure washer is not complete without a high-performance and pressure head pumping unit. All causes of a high pressure washer malfunction can be divided into malfunctions of the pump, its electrical part and breakdowns of individual units on all kinds of installation accessories.
During its operation, the pumping part is subjected to the most basic loads during friction of moving parts, pressure on all components of the structure.
Therefore, you should constantly monitor the wear of the main parts of the pump and the electric motor, tighten the loosened fasteners in time and replace the worn out and lost their functions units and parts of automatic control systems in time.
Consider a few of the most common and frequent breakdowns that are found on all brands of pressure washers.
Often, even on the "coolest" models of high-pressure washers, after a while, problems appear with the operation of the high-pressure automation, which is responsible for maintaining a certain value of water pressure in the installation.
At the same time, the pump starts to start when the consumable pistol is pressed, but after a few seconds the automation turns off the pump. At the same time, water from the pistol goes in a thin stream with absolutely no pressure, which can create a normally working device.
This problem can only be eliminated in service centers, but we will try to generalize this malfunction and try to figure out why this can happen.
High pressure is created by a high-speed plunger pump with multiple pistons (from 2 to 4), which is spun by an asynchronous electric motor.
In our case, the motor works, the pump with pistons spins up, but the contact group, which is responsible for the timely shutdown of the pump when a certain pressure in the pump is reached and before the trigger of the pistol, does not work at the right moment and the pump does not create a pressure of a certain value.
there is a leakage of water from the drain hose or from the pump body itself;
possible clogging of the fine filter at the inlet; the hole on the nozzle is clogged;
bypass valves on the water inlet system to the pump do not work;
seizes the piston rod of the lever for turning off the motor circuit (bypass), which is included in the automatic high pressure maintenance in the pump;
the spring force has weakened, which should return the lever (bypass) to its original position when the pressure in the pump drops and the motor does not start on time.
All problems not related to disassembling the unit can be done independently: clean the nozzles, rinse the filter, try to check the fastening of the hose at the outlet and inlet nozzles.
If the pressure washer works intermittently, and you cannot fix its operation with simple actions, contact the service center to specialists.
There are times when the electric motor of the high-pressure washer hums (works), and water does not flow from the pistol when the trigger is pressed or flows under low pressure.
This can happen for several reasons that you can fix on your own:
The water tap is closed - open the tap.
The bypass valves at the pump inlet are clogged - check the operation of the valves by turning off the main valve and turning on the engine of the device, the hose will begin to flatten due to the discharged pressure.
Air has entered the pumping part of the device due to a loose fit of the supply hose to the sink - make the correct connection of the sink to the water main, let the pump run without connecting the high pressure hose to the nozzle. After 2 minutes of pump operation, water should appear without air bubbles. We turn off the pump and put on the high pressure hose and the gun.
Switch off the unit, disconnect the inlet main hose and use pliers to remove the fine filter from its seat. Rinse the filter from clogging in a stream of running water.
If the situation repeats, consult a specialist. The pressure relief valve stem of the high pressure maintainer may have jammed or the spring of this part may be weakened. Possible damage to the stem itself or to the rubber seal on the bypass.
After some work, your sink, when the trigger of the gun is closed, continues to work and does not disconnect from the mains.
Try to turn off the sink using the main switch on the unit body.
The contacts on the microswitch of the automatic pressure support system in the pump may have oxidized. Check the operation of the automation several times, turning the pump into operation manually.
If the situation repeats, you can try to remove the protective case from the sink and clean the contacts on the de-energized terminals of the pressure switch and on the microswitch.
If these measures did not fix the problem, contact the service center for help.
Over time, the pressure washer begins to fail when turned on, or it can suddenly turn off the engine itself.
These pressure washer failures can occur for a number of reasons:
Failure of the main switch.
Oxidation or damage to the power wires at the main switch, through which the pump motor is powered.
Breakage or overheating of the motor winding.
Jammed gauge valve in the chemistry supply system. Over time, as a result of oxidation of the space between the aluminum pump casing and the rubber or plastic gaskets on the bypass valve stem, it leads to the formation of rust and sticking of the valve in its seat and, as a result, to pump malfunctions.
All minor faults in the form of stripping the terminals, temporarily cooling the motor winding on a disconnected device, checking the electrical circuit of the main switch and similar problems, you can fix in your garage workshop yourself.
Larger problems associated with complete or partial disassembly of the pressure washer should be trusted by the specialists of the service center. They will strip the valve seats or replace the complete pump cover assembly with new parts. Fitting the valve seat and grinding it requires a special precision tool.
During the warranty period for the purchased unit, no independent repair work on the unit is allowed. In addition to external cleaning and installation and assembly work related to the preparation of the device for operation.
Unauthorized repairs or tampering with the design of the device will deprive you of further service and warranty maintenance of the unit.
