DIY nilfisk car wash repair

In detail: do-it-yourself nilfisk car wash repair from a real master for the site my.housecope.com.

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;
with the use of a special nozzle-brush, you can do sewage cleaning using a pipe cleaning kit;
By adding special tools, you can organize the foam treatment of various painted surfaces by 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.

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!

From the author: Hello, friends! The development and implementation of innovative technologies in almost all industries contributes to the emergence of new 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 washer 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, excellent and well-organized service in any part of 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.

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.
Reassemble the mini-sink in the reverse order, remembering to add new oil.

Important! It is difficult to find an original oil, 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, so it is much wiser to contact a service center.

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 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.
