The sink began to work intermittently and there is no pressure. What to do? How to fix a Karcher sink with your own hands?
The reason you described may lie in the incorrect operation of the water pump. To fix it, you need to: first of all, turn off the power supply, then remove the plastic casing (case) and get close to the pump itself. The pump should be removed and disassembled in detail, this is the only way you can determine the cause. Wear of O-rings and much more visually immediately after disassembly, all defects are clearly visible. Often, solid particles get into the water, which can disrupt the operation of the pump. When the pump is disassembled
when all the parts are removed, they need to be put in warm water with citric acid so that all the old grease goes away. Then wipe everything thoroughly and replace every part with defects.
You write that there is no pressure, most likely the reason is in this bypass valve
But I will immediately emphasize that there are quite a few models of Karcher high-pressure washers, the reasons for breakdowns are even more, because the technique is rather complicated.
Correct diagnosis is 90% of the repair success.
The valve that I wrote about above can stick, the reason is dirt.
Sometimes it is enough just to rinse it, clean it and lubricate it, this is a collapsible unit, it is better to take a branded Karcher lubricant, in our case we need silicone lubricant.
We remove the casing (usually it is 8 bolts), put the device lying down with the wheels up.
Next, we remove the pipe (plastic), here you need a hex key, it is held on three bolts.
We take out the valve itself with pliers.
Examined, rubbed, want to disassemble into components.
Lubricated, assembled the sink in reverse order and started it.
If everything is in order, then we have managed with small efforts (investments); if not, we change the valve to a new one.
When reassembling, check the mesh filter, it is located in the branch pipe (see above), the mesh may be torn due to this, dirt gets on the valve.
The filter is only cleaned, it is not repaired, if it is torn, we buy a new one and replace it.
If there are interruptions in work in Karcher, as you correctly noticed this may occur due to a loss of pressure, then the water supply stops until the device reaches the required pressure and so on constantly.
As I noticed, there can be several reasons, at least two.
You should not go straight into the water pump, first you need to look at the contamination of the filter and the water supply system in general, it is quite possible that there is simply no access to water.
If everything is normal with pollution, or rather everything is clean, then check the tightness of the system, there is a possibility that the pressure is being released due to water leakage from the system, perhaps the hose just cracked or the cuff is leaking.
If the first two examinations did not reveal anything, then the water pump is diagnosed and repaired.
They call it correctly - pump.
I personally recommend installing a new pump assembly, due to the fact that in the old one there may be a production and replacement of a repair kit will not work.
And for the price there is not much difference, so the pump costs from 2000 to 5000 steering wheels, if assembled, and repair kits from 1000 to 4000 rubles.
To choose a pump, you need to know the Karcher model, and in some cases, how it looks.
Here is an example of replacing the pump for the karcher k 4.75 model

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:
the main purpose of washing cars (cars, trucks), special equipment;
further in importance: washing of courtyards, workshops, building facades, using a high-pressure extension hose;
the third function (for industrial devices) pumping out liquid from flooded places;
using a special brush nozzle, you can clean the sewer using a pipe cleaning kit;
by adding special tools, you can organize the foam treatment of various painted surfaces using a jet tube with a nozzle.
There are several types of sinks:
household - this is the most acceptable equipment for cleaning dirty surfaces mechanically in any hard-to-reach places. The difference between domestic and industrial washes is only in their compactness and mobility, low weight and size, which allows you to enjoy the result of cleanliness yourself, to save time at home, in the country, in the garage.
with water heating - designed for organizing cleaning of hard surfaces by double washing (high pressure, hot water).
without heating water. For example: Karcher K2 minisink
autonomous - access to the power grid is not necessary, performance is provided by a powerful gasoline engine. For example: autonomous device Karcher HD 9/23 G of the Advanced series
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.

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
various 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 put the rubber seal aside.
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 with 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.
Video instructions for eliminating possible breakdowns of Karcher equipment can be viewed below:
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 sink, 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:
The champion will appeal to those who appreciate the reliability and ease of use of technology.
Calm is an amazingly compact pressure washer, no less durable than the first.
Hooter - universal, makes it possible to use in different jobs, however, experienced clients already know that the Chinese Hooter often requires do-it-yourself repair.
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.
