asko dishwasher drain pump won't stop

Sometimes, the Asko dishwasher drain pump won’t stop. That will prevent you from starting a new cycle.

Instead, you will have to forcefully shut the appliance, which risks damaging some electronic components. So what should you do?

Since the drain pump is not stopping, you must check if it is defective and see if the float switch can communicate correctly. Other potential culprits involve the solenoid or the amount of clog in the whole system, but there could also be a leak.

The guide below will teach all the steps to analyze the situation and fix the problem without spending much. If replacements are necessary, they will require you to buy cheap components.

Asko Dishwasher Drain Pump Won’t Stop – Reasons

why the asko dishwasher drain pump won't stop

The Asko dishwasher is very convenient because of all its features. However, all appliances might show issues over time simply because parts are becoming worn.

For example, are you seeing that your dishwasher keeps draining when empty?

Let’s check what reasons explain that:

Faulty Drain Pump

The most obvious cause would be the drain pump itself. It doesn’t stop when it should because it does not communicate correctly with other parts or is defective beyond repair.

Float Switch

The float switch is a component that detects the water level in the dishwasher. Sometimes it can trick the dishwasher into thinking there is excess water, causing the drain pump to run continuously.

Clogged Dishwasher

Perhaps the dishwasher is not truly empty, and the water can’t get out because the filters and other components are clogged.

Defective Solenoid Valve

A defect in the solenoid valve usually will prevent the dishwasher from draining. However, it could still be the culprit because of its implicit function.

We’ve checked the main possible culprits behind the annoying situation. Next, it is time to look at how you can solve the problem.

Some solutions will require you to change parts, so you better have your tool kit at hand!

1. Check The Drain Pump

Since it is the drain pump (also called drain impeller), the main part showing problems, it is the first that we will also assess.

Only because it is not stopping, it doesn’t mean it is defective. However, it is best to eliminate any suspicion right away.

So here is what you will do:

  1. Place the appliance on a flat surface;
  2. Locate the drain impeller at the bottom of the dishwasher (near the motor);
  3. Remove the retaining clip or nut that secures the component;
  4. Remove the impeller/pump.

Examine The Pump

Once you remove the drain pump, you should check how it looks and if it is functioning.

Check for blockages on any of its parts. Is there debris or dirt? Clean it if necessary. 

Also, check its wiring and the dishwasher’s wiring nearby the pump. It is a good idea to tighten any loose wires and clean the overall region.

Replace If Necessary

Are the circuits in the drain pump bad? Perhaps it is still active, but it won’t be able to stop when it should.

Thus, you could buy a new drain pump and test it:

  1. Put the new drain pump in place of the old one
  2. Secure it with the clip/nut
  3. Return your dishwasher to its proper place
  4. Test the appliance with the new pump in place.

2. Inspect The Float Switch

The float switch is one of many dishwasher components responsible for controlling the water flux.

Beyond controlling it, it communicates with other parts to tell when to stop. If the drain pump cannot stop, it might be due to the float switch not functioning well.

Here is what you will do:

  1. Find the float assembly;
  2. Locate the wires to find the switch;
  3. Detach carefully;

Test And Replace

Once you have detached the float switch, you want to clean it of any debris and dirt. Next, inspect its wires for any sign of damage.

Also, do this:

  1. Grab a multimeter;
  2. Turn the device’s ohms dial to the multiplier of 1;
  3. Touch its probes to the switch’s wires.

The test might indicate that the issue is on the switch’s wiring. If you are an expert with wires, you might be able to identify where the issue lies exactly and fix it.

If not, simply replace the part to avoid further issues:

  1. Buy a new float switch that matches your dishwasher’s layout;
  2. Disconnect the old switch from the float;
  3. Put the new component in place;
  4. Connect the wires correctly.

3. Check For Leaks

try check for leaks

If the issue is not on the float switch or drain pump itself, you might start looking for leaks on any dishwasher components.

Leaks could come from the in-water hose or any other place where water flows. If there is a leak, the machine might detect it, and the drain pump will keep working to try and get the water out.

Do the following:

  1. Detach the main water hose;
  2. Check if there is damage to it;
  3. If there is, buy a new hose to replace it.

Vacuum The Water Out

Even if you eliminate the leak source, there may still be water inside the dishwasher in some places where it is harder to check.

A very successful method is this:

  1. Locate the two screens at the top of the door;
  2. Unscrew them and remove them;
  3. Tilt the appliance forward;
  4. Unscrew the filters at the bottom;
  5. Find if there is water inside the appliance;
  6. Use a vacuum to get the water out.
Note: After removing the water, reassemble the appliance and put it back into place. The drain pump shouldn't show any more issues.

4. Analyze The Solenoid

analyze the solenoid

Another component that could mislead your drain pump into “thinking” that there is remaining water is the solenoid.

It is one more component responsible for the correct water flow, and it can start miscommunicating.

Here is how to access and check it:

  1. Remove the access panel
  2. Locate the solenoid valve
  3. Disconnect the electric connections
  4. Uninstall the water supply lines
  5. Remove the valve

Check for rust and signs of damage, and test it with a multimeter if possible. You should set the multimeter to continuity and see how the solenoid behaves. 

Replacing The Solenoid

Once you find the solenoid at fault, you must search for an exact replacement. It must have the same design so it will fit on your dishwasher.


replacing dishwasher solenoid
  1. Carefully attach the new solenoid into its place;
  2. Connect the water supply;
  3. Attach the wires;
  4. Reassemble the panel;
  5. Test the appliance.

5. Unclog The Dishwasher

Are you sure that your dishwasher is capable of emptying? Perhaps the drain pump won’t stop working because the dishwasher is clogged.

Thus, the dishwasher sensors tell the drain pump that there is still water. However, the water can’t get out completely. 

  1. Open the dishwasher door;
  2. Locate the filter on its bottom;
  3. Remove the filter;
  4. Rinse it under running water;
  5. If any part is detachable, detach it and wash it.

If there is persistent dirt and debris, you might want to use vinegar, bicarbonate, and soap to remove everything.

Perform An Unclogging Cycle

After the filter is very clean, you must attach it to the dishwasher. Then, check if you have any cleaning items that help unclog dishwashers.

If not, vinegar will do.

perform an unclogging cycle
  1. Pour vinegar or another unclogging cleaning item into the dispenser;
  2. Set the dishwasher to run a normal cycle;
  3. Check if the drain pump stops.
Note: If you suspect that clog is the issue, you might want to check other easy-access components where the water flows. Eliminating all debris will make your dishwasher last longer.

What We Learned

It is very odd when the Asko dishwasher drain pump won’t stop. The dishwasher might look empty, but you might ask yourself if it truly is.

The issue could lie in some components not communicating correctly or the dishwasher failing to empty correctly.

Now you have all the info you need to fix your Asko dishwasher!
