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:
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.
It often happens that devices that have become habitual fail. The equipment will have to be handed over for repair, bought a new one, or try to repair it on your own. It may well turn out that self-repair will not cause difficulties.
The low-cost high-pressure car wash (HPH) Elitech 1500 PC has served several seasons, having repeatedly paid for itself. One fine day, my favorite car wash refused to work. The required pressure was absent, and water flowed from the body.
After removing the plastic cover, the problem was identified. Due to the fact that the AED was left to winter at the dacha with water inside, the manometric shut-off valve was damaged. The water inside froze, and the ice damaged the plastic case.
An attempt to fill the crack with glue did not help, a fountain gushed out from under the plastic pusher, water got into the case with a microswitch (photo 1). It was decided to replace the faulty part.
Finding a spare part caused the greatest difficulty. Substitutes available on the Internet were offered for several thousand rubles, which is almost half the price of a new AVD. The market did not help either, the sellers could not even identify the valve. Oddly enough, the necessary spare part was found in an official service center.
The valve article (0901081280) was found on the Internet. It turned out that it is offered complete with a switch and a set of wires (photo 2), and the price is less than 300 rubles. Well, such a renovation is economically justified.
It is most convenient to unscrew the faulty valve with a head by 24 (photo 3, 4, 5). A serviceable part is carefully inserted (photo 6) and screwed into place. The switch body is connected to the valve. It is necessary to press down with effort on the body (photo 7). Without collecting the casing, water is connected to the mini-sink and the operability is checked. Everything, the repair is over.
For reassurance, you can also replace the switch body at the same time, because water got into it. This is also easy to do. First you need to open the black block that contains the wires. You need to unscrew two screws (photo 8 and 9). It is better to remember the position of the wires in the block right away, otherwise you will have to tinker with their reverse laying (photo 10).
Next, the wires are disconnected from the old switch body and new ones are connected. Assembly is carried out upside-down. Now the repair is over for sure.
Before we understand the reasons for the breakdown of sinks, let's first consider the variety of devices of this type.Different types of sinks are used depending on the needs of the user. The difference is in the way of operation and productivity. This range of high-pressure washers needs to be described in more detail:
After winter, car enthusiasts often face the problem of building up operating pressure in a car wash. It seems that the car wash is working (the engine is noisy), but the pressure of the jet is not enough for efficient operation. In such cases, most often the reason lies in the malfunction of the bypass valve.
But before repairing, you should rinse and clean the nozzles well. If the removal of contaminants did not help, then this means that the bypass is jammed, and it releases pressure into the return line, as a result of which, even after releasing the trigger of the gun, the pump continues to work forcing the water to circulate in a circle. To check, you can simply change the jet nozzle to a mud cutter, the problem remains, so we can safely proceed to the repair.
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.

Most often, the repair of a Nilfisk high pressure washer is required if you do not follow the rules of its operation. So, if you do not monitor the voltage in the network, the likelihood of engine failure is high. The use of low-quality, hard water is a direct path to oil seal malfunctions. The washing hose is also very vulnerable and must be handled with great care.

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 loose fasteners in time and replace 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;
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.

After a year of operation, the gun broke down and was converted to a regular water tap. It has become even more convenient to use and there are no unnecessary inclusions - switching off the device when the trigger is released.
I also spent a year and water began to spray from the pistol, they are weak.
YOU are persecuting! the end does not justify the means.
Vova thanks for the advice put the faucet all the class like from me. Good luck.
idiot, that switch work with 2 way!
and where did you buy it?
Tell me where to buy the same new pistol? I can't find it anywhere
to do this, you must at least be a turner. and if you are not a turner, then how much the turner will take. a new sink in the store costs 6300r
Vladimir, good afternoon. Made according to your option, but instead of carving, I used epoxy resin, will it withstand?
Video (click to play).
Vladimir, good afternoon, how can I contact you and ask a few questions about your design. I have a similar pistol, I haven’t put any gaskets, because of the pressure generated, it turns them out or just tears them off and a new gasket is enough for 20 minutes of washing. Thank you
