Karcher vacuum cleaner does not vacuum((((
Good afternoon, dear ones.
This is the situation: a Karcher vacuum cleaner with an aqua filter has completely lost its suction power. That is, it DOES NOT SUCK dust((((((((((What’s wrong with him? How can I help him? Thank you)))) Link to description
Thank you, we did it. Everything worked)))))))
I periodically wash the fine filter in my SE3001; it’s written in the instructions, your filter is the same.
Personally, I have 2 hoses, one for wet cleaning and the other for dry cleaning, the same as yours (the problem is that I just periodically clean this place and that’s all), garbage also tends to collect on the bend of the curved solid spout, especially if you collect something large.
do not forget that at the engine output there is also a small filter that is also periodically cleaned and changed
Another piece of advice is to pull out the noise insulation filter, it will rattle a little more, but it will also add at least 20% more power.
Thanks for the advice, about all the filters I know and clean them)))) I was just VERY surprised at the garbage collection site))))) But it doesn’t have wet cleaning, there’s only an aquafilter)))
I also have a Kersh 5500 years old, 8 probably from the first I still use my original filter mainly for collecting construction waste, naturally on a household scale, just after each cleaning I wash the filter under running water at the same time I clean it with a long-haired clothes brush, then I dry it on batteries or in the summer on the balcony with a second filter I use it for regular cleaning in the apartment, I didn’t notice a big difference in the suction power, but after a year of use I threw out the hepa filter; I didn’t put a vacuum cleaner in its place; I’m very pleased with everything, it’s brilliant and the Germans are just great

Diagnostics and repair of Karcher vacuum cleaners
Karcher vacuum cleaners are of high quality and have proven themselves to be the best in everyday life. However, they sometimes fail. At the same time, many vacuum cleaner breakdowns are not so serious and before contacting a service center, you can carry out diagnostics and try to fix the faults yourself. For example, diagnostics and repair of LG vacuum cleaners very often help to preserve equipment, as well as diagnostics and repair of Samsung vacuum cleaners. So why not try the same principle with Karcher products?
According to statistics from service centers that repair Karcher vacuum cleaners, the main breakdowns of the devices are:
It is not difficult to determine which of the listed problems is occurring and which spare parts to buy. It is enough to diagnose and eliminate faults.
Reasons why liquid is not absorbed
There are several basic reasons why a Karcher car wash does not suck in water. There could be several explanations for this:
- Lack of water supply, due to which the equipment works, but nothing comes out. This can happen if the water runs out in the container or the water supply stops during operation.
- The supply pipe is damaged or dirty. If the supply hose is bent, Karcher does not pump water, and it appears that it is faulty.
- Dirty filter. If the owner has not changed the filter element for a long time, the latter becomes dirty and does not allow liquid to pass through, or it passes in a limited volume. In this case, the washer sucks in liquid in the maximum volume, but there is no liquid at the outlet.
- Deterioration of tightness. A common situation is when Karcher does not absorb water due to damage to the housing. As a result, the pump sucks in air and malfunctions occur at the outlet. In this case, the device itself does not work correctly or does not function at all.
- Valve block. The breakdown of this element is one of the reasons why Karcher does not pump. In this case, all the work of the moving pump plungers will be neutralized without creating the required pressure. As a result, the liquid comes out in jerks, or the device does not suck it in at all. In this case, electricity from the network is consumed in full.
- Valve failure. Due to operation in difficult operating conditions, the valves can become damaged, causing them to stop performing their functions and “get stuck” in one position. A possible reason why Karcher hums but does not pump water may be contamination of the devices.
The vacuum cleaner works, but stops sucking up dust - why is this happening?
The process of using household appliances is often accompanied by problems. Some don't require much effort to solve. If you know why the vacuum cleaner has poor suction, you can fix the problem without involving a technician. There are several reasons for the breakdown. Simple diagnostics help identify them.
The vacuum cleaner works, but does not suck up dust well and gets hot
There are few reasons why a vacuum cleaner suddenly stops working effectively. This mainly concerns clogged filters, the dust container, the hose and the pipe on which the brush is mounted. Less common are reasons related to purely technical problems, such as incorrect operation of the electric motor.
What to do if power drops
All of the above troubles necessarily lead to a drop in air suction. Accordingly, the power of the unit also decreases, that is, you can forget about cleanliness of cleaning. The vacuum cleaner works, but removes dust ineffectively.
The hostess senses this immediately and begins to get nervous. The first thing you need to do is touch the body of the device. If it gets very hot, this indicates that the motor is running under load. This should not be allowed, because the engine should not operate in this mode for a long time. It will simply burn out, which will lead to large financial costs. Or it may even lead to the failure of the entire vacuum cleaner, which will have to be replaced with a new one.
Therefore, if the housing has become hot, the unit must be turned off and not used until the cause of this situation is identified.
What to do
Taking into account the above, it is not difficult to figure out what to do in a situation when Karcher does not pump water and does not suck it in. Here are the basic steps that can help resolve the issue.
Check the feed
First, make sure that the problem is not related to the feed. Make sure there is liquid in the working container or there is sufficient pressure from the water supply system.
Inspect the supply pipe
Inspect the pipe through which the liquid is supplied. It may be bent or damaged, causing the Karcher to not draw water in or release it through the gun. As a diagnostic measure, try connecting a supply pipe that is known to be good.
Rinse the filter
In many cases, Karcher does not pump water due to contamination of the filter element. Due to accumulated debris, it does not allow liquid to pass through itself, and there is no pressure at the outlet. To solve the problem, remove the filter and rinse it under running water, and then put it back in place and check whether the equipment is sucking in liquid or not.
Check the housing for leaks
Inspect the device for leaks. If air is sucked somewhere, this leads to malfunction and Karcher does not supply water, or the pressure drops significantly. Once the sealing issues are resolved, the problem should be resolved.
Carry out repairs
A situation cannot be ruled out when the Karcher pump does not work, and the valve block or the valves themselves fall into the risk zone. Such equipment is easy to find on sale and replace. The work can be done independently if you have experience and knowledge of equipment design, or entrusted to specialists. The latter option is preferable, because the service technicians have all the necessary equipment.
Particular attention should be paid to the situation when Karcher does not suck in water due to an engine malfunction. In this case, it requires replacement or repair. In all cases, it is important to be careful when disassembling and reassembling to avoid mistakes.
The disassembly algorithm is as follows:
- Unscrew the bolts and remove the handle.
- Remove the wheel caps and remove the wheels themselves. You can pry them off with a screwdriver.
- Place the equipment on a stand or table.
- Unscrew the supply inlet. It is attached to the housing using threads.
- Take out the filter and look at its condition.
- Replace it or wash it if necessary.
- Remove the holder.
- Remove the eight star screws.
- Remove the second half of the housing.
After this, there is a motor in front of you, which you need to remove for ease of operation. Next, you need to carefully disassemble it in order to get to the valve and perform its replacement/repair. Be careful at this stage and remember that the power section is secured using locking elements that can be reached using pliers.
Now you know why Karcher does not suck in water, and what can be done to fix this problem. Start with a simple check for leaks, water supply and filter, and if there is a serious problem, disassembly and repair may be required.
In the comments, tell us which recommendation helped you, and what other steps can help in a situation where Karcher does not suck in water.

How to find the reason yourself
There is no need to take the vacuum cleaner to the specialist right away. There are several reasons that can easily be eliminated on your own. Let's look at them separately.
Checking the dust container and filters
The first thing to do is open the compartment where the dust collector is located.
It is necessary to explain that the vacuum cleaner is designed like a ventilation system. That is, air is sucked in on one side and thrown out on the other. There are simply several parts and assemblies installed inside the device that stop and collect the sucked dust so that the sucked air does not pass back into the room being cleaned. Hence the rather stringent requirements for dust collectors.
If it is a bag, then it is made of dense filtration material folded in several layers. That is, air along with dust gets inside the bag and passes through it, leaving dust masses inside. 100% dust does not remain inside the bag, some of it leaks out because the air pressure is quite high. So, final cleaning is carried out by special filters installed along the direction of air movement.
And since after the dust collection compartment there is a section with an electric motor, it is important to protect the latter from the smallest particles of dirt. The thing is that, although the motor has a level of protection, dust does its negative work over time. Therefore, vacuum cleaner manufacturers install several filtration barriers using high-quality filtration materials.
It is these filters that, when clogged, do not allow air flow to pass through them well. Therefore, the vacuum cleaner does not suck as expected. This means that filters need to be cleaned periodically. This is done manually using a brush. You can do it without it - by cleaning the filtration element with your hands or another object, or by tapping.
As for the bag, it is simply emptied of its contents and shaken out well. And it is again ready to collect small debris and dust, plus delay the latter from penetrating into the engine compartment.
Some manufacturers supply vacuum cleaners with paper bags rather than fabric ones. They perform the same functions, but there is no point in cleaning them. They are simply thrown into the trash, installing a new one in the compartment.
The frequency of cleaning filter bags depends on the intensity of use of the vacuum cleaner. The more we use, the more often we clean.
Plastic containers
Vacuum cleaning bags are gradually disappearing into oblivion. They have been replaced by plastic containers that operate on the principle of a cyclone. That is, inside this dust collector, when the motor is turned on, an air funnel is formed, in which all the dust collects. As soon as the electric motor turns off, it immediately falls to the bottom of the container.
A plastic container installed instead of a bag has made life easier for housewives, because garbage disposal is much easier here:
Aqua filters
And although dirty fluid has to be replaced with a new one often, this still does not affect the suction power in any way. This vacuum cleaner will work efficiently. The only thing is that you will have to look out for additional filters.
But such models of vacuum cleaners have one feature. The water filter must be filled with a certain volume of water. That is, no more and no less, which is why there is a fill level on the container. The fact is that when air moves at great speed, it also takes water dust with it. But the air inside the device performs an important function - it cools the motor. If water gets into the air mass, this will soon affect the operation of the electric motor. It’s not uncommon for the engine to simply “burn out.”
How to fix it?
If we immediately exclude fairly rare cases in which cleaning individual parts can help, it turns out that repair in its pure form is practically impossible and the answer to the question “Why doesn’t Karcher pump water from a bucket?” The only solution would be a complete replacement of the valve block. Fortunately, this item is not difficult to find on sale, which means that a malfunction of the mini washer will not ruin your life for too long.
Is it possible to replace this part of the pump yourself? This process should not be particularly difficult, however, at least basic technical skills may be required. We can say that if your Karcher does not pump water, then you will be able to cope with the problem yourself by purchasing the necessary spare parts first. The main thing to remember is to ensure that the device is assembled correctly after replacing the required part, so that instead of fixing the problem, you don’t make several new ones.

Ways to solve problems
Having considered why vacuum cleaners have poor suction and heat, it is worth familiarizing yourself with the solution to these problems.
Everything related to the electric motor cannot be repaired on your own. This requires specialist intervention. Vacuum cleaner manufacturers are trying to improve product quality by installing high-quality components and parts. And if they fail, then more often than not they have served their time. Therefore, there is no point in repairing them. In workshops they are simply replaced with new ones.
A burnt-out motor winding can be replaced, but this still reduces the quality of the motor. Therefore, experts recommend changing it or purchasing a new vacuum cleaner. The winding burns out for four reasons:
Problems with liquids often arise. If the vacuum cleaner is not washable and does not have an aqua filter, then it cannot collect spilled liquids. Especially if there is a paper bag installed inside the vacuum cleaner. With any protection, even a small volume of water will penetrate inside the motor and reduce its service life.
Troubleshooting the board is possible, but only in a workshop. Here you have to look for an element that has burned out or stopped functioning due to the end of its service life. It is usually changed. It is rare that the entire plateau has to be removed. But this also happens.
If the voltage in the house is low, then the solution is simple - install a step-up transformer.
Product Questions
Cordless electric brooms
Is an electric broom suitable for removing pet hair?
Yes, it comes with 2 brushes – a standard one and one for animal hair. The latter allows you to easily and hygienically clean hair from any floor covering.
What to do if the battery drains quickly?
The cordless electric broom should be charged when switched off for at least 3.5 hours. If the battery does not charge even after charging for 14 hours, contact your nearest service partner.
What should I do if the brush stops rotating?
Charge the battery and clean the brush from possible contamination (for example, wound rope, etc.).
What to do if the cordless electric broom moves jerkily?
Charge the battery and clean the brush or replace it if worn.
What to do if the cordless electric broom is difficult to move?
Check the condition of the wheels, clean or replace them if necessary.
Steam cleaners / steam ironing system
Can I use a steam cleaner to clean laminate/parquet flooring?
Using a steam cleaner equipped with a steam flow regulator, you can even clean laminate or parquet (but not waxed or oiled!). With the steam supply set to minimum, treat the floor with a nozzle with two cloths (= 4 layers), reducing the direct impact of steam on the surface. Avoid prolonged exposure of the same area of the floor to steam and the formation of pools of water. If these recommendations are followed, the moisture quickly evaporates and there are no streaks left on the floor.
Useful tips
The service life of a vacuum cleaner is affected by various parameters. Of course, first of all, a lot depends on the quality of production: high-quality components and parts, as well as their assembly into a single whole. Not all manufacturers can guarantee high quality assembly, and then there are more details themselves. But even such vacuum cleaners can work for several years without creating problems.
It is important to consider the following requirements:
There is an enviable variety of vacuum cleaners on the market. There are inexpensive models, and there are premium ones. But they all have the same problem if the device is not used correctly. This is a drop in the efficiency of collecting dust and small debris, after which house cleaning cannot be called clean. Small problems can be solved independently, but there are some that require the intervention of a specialist. But, if you strictly follow the operating instructions from the manufacturer, you can guarantee that the device will work for a long time and without problems.

If a vacuum cleaner with a Karcher aqua filter is malfunctioning
If a vacuum cleaner with a Kärcher DS aqua filter has problems, should it be taken to a service center or can you try to fix the problem yourself? We have summarized all the problems that vacuum cleaner owners come to us with and identified the main ones.
Why does the suction power of a vacuum cleaner with a short service life decrease?
There may be several reasons:
If the above measures do not lead to an increase in suction power, this is a reason to contact a service center.
Releasing the power button causes the vacuum cleaner to spontaneously stop working. How can I fix this?
Most likely, the switch is faulty, but only a specialist can accurately determine the problem, so it is better to contact the service center directly.
How often do filters need to be changed?
For normal operation of the vacuum cleaner, it is enough to change the filters once a year. Premature replacement is necessary if the filter capacity is impaired or damaged, as well as if the vacuum cleaner is used intensively.
It is better to entrust the repair of household appliances to specialists. Competent consultants and experienced craftsmen of the Karcher service center will help extend the life of your household appliances, and they will delight you with their impeccable work for a long time.

What's broken?
Since the description of the problem itself indicates a completely working engine, if the Karcher hums but does not pump water, the reasons will most likely relate to the functioning of the pump.
With a relatively simple design, it contains a number of relatively sensitive parts, the breakdown of which leads to the results described: 1. Valve block .
A malfunction of this element will lead to the fact that all the work of the moving plungers of the pump will go to nowhere, without creating pressure. As a result, Karcher pumps water in spurts, or does not pump at all, only wasting electricity. 2. The valves themselves. Designed to work under high pressure conditions, these elements eventually cease to perform their functions properly and “get stuck” in one position. If this situation is related to their contamination, cleaning them could theoretically help.
3. Block body
. If the Karcher K5 does not pump water, it is likely that this is due to a leaky housing. Such a pump will suck in air instead of water, which will lead to the observed undesirable results.
This is just a basic list of reasons why Karcher does not pump water. Most service center workers have encountered other reasons, however, they can be considered too “exotic” to be fully considered in this article.
Search for reasons
Diagnostics always helps to determine the cause of poor dust absorption. The procedure can be performed by anyone who knows how to use a screwdriver. However, it may not come to disassembling the vacuum cleaner if the breakdown does not affect the electrical part of the unit.
Often, a superficial diagnosis allows us to identify the following causes of poor absorption:
If these causes are not identified during diagnosis, the problem lies inside the vacuum cleaner. The weakening of the suction force occurs due to a decrease in the power of the electric motor. The reason may be brush wear, contamination of the armature commutator, loose bearings, or the formation of thick dust deposits on the fan impeller. A loss of power sometimes occurs when an electronic unit fails. As a result, the control wheel cannot change the engine speed or it begins to “float”.
To carry out superficial diagnostics, all components are disconnected from the vacuum cleaner. The inspection begins with the working nozzle, then moves on to the telescopic handle and corrugated hose. The components must be free of cracks, holes and other defects. It is important to check the inside for any stuck objects.
The dust collector and filter on the exhaust of the vacuum cleaner are further checked. These two components greatly influence the suction power. The disposable filter is replaced with a new one, and the reusable fabric bag is washed well.
Cyclone vacuum cleaners have an additional foam filter between the motor and the garbage container. The plate becomes heavily clogged with dust and needs to be washed. There is another filter on the exhaust. If it is clogged with dust, the exhaust air becomes obstructed and returns to the fan, reducing the suction power.
Ways to solve problems
Diagnostics only helps to find the cause of the vacuum cleaner malfunction. Further actions are aimed at eliminating the breakdown.
Dust collector
Overfilling the dust container with debris is the most common problem of poor suction. For any vacuum cleaner, the bag or container should not be filled more than 80%. As the clogging increases, the draft weakens or disappears completely.
Manufacturers equip expensive models with light indicators for when the dust collector is full. The green light indicates normal operation. When the indicator glows red, the dust bin is full and requires emptying. Cheap vacuum cleaners do not have this function. The dust collector has to be checked after each cleaning.
Fixing the problem of a dirty dust bin is easy. With a cyclone, you simply need to throw the garbage out of the container. A disposable paper bag is only thrown away and a new one is put in its place. The dust collector cannot be used a second time. After use and thorough shaking, the paper walls of the bag weaken. A re-installed disposable dust collector will be torn apart by a strong air flow, and dust will be drawn into the fan.
Housewives always just empty reusable fabric dust collectors. The cleaning method is good, but not effective. A large amount of dust remains between the fibers of the fabric, blocking the free passage of air. After using fabric bags several times, rinse them in clean water.
The dust collector may not be at fault if the power regulator is tightly screwed on. Sometimes turning the wheel can solve the problem of poor suction.
Fine filters
Dirty dust collectors receive more attention than fine filters, but in vain. One of them stands in front of the fan. In cyclones, the filter is usually a foam plate enclosed inside a plastic collapsible housing. The foam rubber becomes heavily clogged with dust after each cleaning. The plate is thoroughly knocked out and rinsed in water. Additionally, the plastic filter housing on the back has a fine-mesh mesh. It definitely needs to be washed.
The second fine filter is located on the exhaust of the vacuum cleaner. Usually it is made in the form of a separate box with many cells. The filter prevents dust residues from flying out of the vacuum cleaner into the room. Clogged cells are cleaned with a soft brush or rinsed with clean water. Similar procedures will be successful a couple of times. After 50 hours of operation, the filter must be replaced.
Accessories
The components of the vacuum cleaner include a corrugated hose, a telescopic handle, and working attachments. During cleaning, a large object accidentally pulled in gets jammed at bends or transitions. You can clean the hose and telescopic handle with a long stick without burrs or soft insulated wire. The air channel of the working nozzle is usually curved. It is easier to clean it with something that bends well: wire, cable, elastic PVC rod.
After cleaning, check the wheels on the brush. Hair often gets wrapped around them. If the roller is equipped with bearings, lubricate them.
Additionally, the connection points of all elements are checked. Loose locks, cracks and other defects create air leaks. A broken hose is immediately replaced. The gap is temporarily repaired with an adapter sleeve. The hose is cut, a piece of plastic tube is inserted inside, the joints are clamped with clamps and wrapped with tape.
