Washer no longer draws water

Washer no longer draws water

The washing machine does its job day after day. It is similar to the dishwasher from hardly a budget indispensable. It is even worse if she does not work the way you expect her to do and suddenly nothing works: an error message flashes in the display of the device or the laundry simply does not get clean.

  • Washing machine
  • Lint filter
  • Overflow pan
  • Drain hose
  • Leach pump

If you check it more closely, you will notice that your washing machine will not draw any water at the beginning of the program, so that the washing process stops. This can happen with any washing machine, so it does not matter if you have a machine from Siemens, AEG or a completely different brand at home. However, this is neither a reason to despair nor to call customer service immediately. You also do not have to dispose of the washing machine immediately and buy a new one, because with the instructions from today's article, even inexperienced do-it-yourselfers will be able to find out the cause of the problem and possibly even repair the damage himself.

How a washing machine works

If you want to know why your washing machine suddenly runs out of water, you should first of all consider the individual steps that a washing machine performs during the washing process. In principle, the following principle always applies:

  1. Faucet is turned on.
  2. Depending on the selected program, a certain amount of water enters.
  3. The machine pumps the water back into the drum several times.
  4. The lye ends up
  5. If necessary, the water is pumped back into the washing drum several times.
  6. Now the clear rinsing water is pumped out.
  7. The machine starts the spinning process.
  8. The machine starts to spin

After the eighth step, the washing process is finished and the laundry can be removed.

These components may hinder the water supply

Now that you know how the washing machine works in principle, you already have a good precondition for to find the error for the blocked water supply. However, you should also know what ingredients are considered triggers. Because every washing machine has some components that can make sure that the washing machine can no longer draw any water if they are defective or do not work properly.

Forced locking

The forced locking with shut-off valve circuit is intended to make the washing machine first can open when several minutes have elapsed after pumping out the water. This prevents the water from leaking. A solenoid valve also ensures that the inlet is only released when the front loader's porthole is tightly closed.

Fluff filter

The fluff filter is located in the base area of ​​the washing machine. It picks up lint, buttons, hair, handkerchiefs, and other items that come off during washing. However, once the sieve is clogged, no more water can flow, so you need to clean it at the latest.

Overflow Sump

At the bottom of some washing machines there is an overflow sump with air trap and shut-off valve circuit. Once filled with water, the machine can not be opened. In addition, the air trap is used to check the water level in the machine. When the water rises there, the air condenses over it. According to the pressure thus determined, it is determined whether the water inlet is possible or not.


This comfort feature does not have every washing machine. It is a box on the inlet hose, which measures the amount of water passing through electrically or mechanically. If the water flow is too high, the Aquastop will block the hose. An aqua-stop has the advantage that the tap does not always have to be opened and closed manually.

Determine the problem by exclusion

If a washing machine does not draw water, it is best to find out the cause by means of an exclusion method.

Run the washing machine again and check that it does not draw any water as soon as it enters the water, or only when the water that has already been drained in is to be pumped out.

In the first case, quite different reasons may apply second situation.

Possibility 1: no water is drawn when the water enters the water

Your washing machine is not able to draw any water at all? Then there are several causes that could trigger the problem.

Exclude obvious causes

First, you should exclude the simplest reasons to save work. It therefore makes sense to first of all find answers to the following questions:

  • Did you turn off the tap?
  • Does tap water generally come out?
  • Did you insert the mains plug of the washing machine into the socket?
  • Does the porthole lock and unlock as intended?
  • Does the unit have an aquastop function?

The first four aspects should be resolved quickly. If the aquastop has triggered, the machine can no longer draw water. To find out if this was the case, you can pull off the hose on the washing machine responsible for the feed. Then open the tap. If water does not flow as expected, the aquastop has triggered. Read the instruction manual of your washing machine, what you have to do now. Only if you can exclude these obvious triggers should you continue to investigate the causes

Checking the solenoid valve at the inlet

The water is not drawn into the machine via the pump but via a magnetic shut-off valve. This valve is located directly behind the area where the inlet hose is connected. You can find out if the valve is still working by measuring it. For an electrical measuring device for measuring resistances is useful. It helps you figure out which sensor is not working as intended.

Some do-it-yourselfers advise you to quickly open and close the faucet to build up pressure and release pressure. So sometimes the valve opens and lets water through. In this case, it is obvious that it is broken. However, the method is not recommended because it is not meaningful.

Especially with older washing machines, this procedure usually does not work, because the drain pump and check valve are often still connected in series here. In this case it is essential to check the solenoid valve with a measuring instrument or to consult a service technician.

Option 2: Washing machine does not pump out the water

If the washing machine does not pump out the lye, this may also be the case cause no clear water to run off later in the wash cycle. Also in this case, there are still different causes to choose from. The drain pump can be jammed, for example. It could also be that there is a problem with the contacts on the pump's connection or that the pump is simply broken.

Lye pump jammed

Sometimes the suds pump jams when coins are washed along or the metal brackets are jammed remove from bras. Such objects can get under the bucket wheel of the suds pump and thus ensure that the pump jammed. If the pump hums or buzzes, it is very likely that this problem exists.

Electrical contact problem with the pump

If the problem with the suds pump is not mechanical, you will need a meter again to find the fault. However, first eliminate a contact problem by examining the terminals, cleaning them, and possibly using a contact spray.

If there is a serious problem, the entire pump must be replaced. Do-it-yourselfers with a lot of electrical know-how can do it themselves, while laypersons should hire a service technician without understanding technology.


To find the fault, a wiring diagram is absolutely necessary.


If the washing machine suddenly fails Water does not draw more and therefore no longer washes as usual, that is no reason to despair. You also do not need to dispose of the device immediately or alert the customer service. Instead, we recommend that you first check carefully whether obvious causes can be ruled out. Sometimes it is just the Aquastop function of the machine that disturbs the water supply. Even a clogged lint filter or a full overflow pan can keep water from draining.

If you can rule out the simplest reasons, you can opt out of the problem using the exclusion principle. Unfortunately, electrical defects can also cause the water supply to stop working. In this case, either a sound knowledge of electrical engineering is required to correct the cause, or you have to call a service technician. He can certainly help you and make sure that your washing machine will soon be washed as usual.


If a washing machine suddenly loses water during the washing process, there can be several causes. Sometimes the source of error is obvious, because the problem can occur if the lint filter is clogged or the overflow pan is full. In addition, the machine stops drawing water when the Aquastop has triggered or the porthole is not properly locked. But it can also be more serious causes, such as a defective or jammed drain pump. In addition, the inlet solenoid valve is sometimes responsible for this error.
