asko dishwasher not draining

Is your Asko dishwasher not draining? Different issues in the internal components can cause that.

Dishwashers rely on ducts that drain water and components that deliver the energy for that. 

When your Asko dishwasher is not draining, you must investigate its internal components and replace whatever is defective/broken. Sometimes, a bit of cleaning will do the trick too. Furthermore, a wiring issue can be at fault, so you must be extra careful.

We understand that the above is still a bit vague.

However, it is not recommended that you go and open your dishwasher without a complete understanding of how to fix it.

Because of that, the guide below will teach everything.

Asko Dishwasher Not Draining – Learn The Reasons

why is dishwasher not draining

Asko dishwasher water not draining is a common situation. That does not mean Asko is a bad brand, but only that the most common issue with dishwashers is about draining.

After all, that is one of the most basic functions of the appliance.

When any component within it stops working, draining will become difficult or impossible.

You must be wondering: why is the Asko dishwasher not draining properly?

Below we have multiple answers. 

#1. Clogged Drain/Filter

Food, dirt, and other items may block the dishwasher drain pipe. That stops the dishwashing water flow.

#2. Drain Solenoid Kit

The drain solenoid is responsible for opening the drain valve. When it fails, the drain valve will be stuck.

#3. Defective Pump

the defective pump

Dishwasher pumps remove water. A broken pump might prevent the dishwasher from emptying.

#4. Control Board

As the name suggests, it is responsible for all appliance functions. When it fails, the dishwasher won’t drain.

If this is the issue, calling a professional is advised.

#5. Wiring issue

Any loose or damaged wiring that controls the pump can cause the dishwasher not to drain.

How To Fix The Draining Issue On An Asko Dishwasher

fix the draining issue on asko dishwasher

As you can see, many defects can be at fault when you find the Asko Dishwasher not draining properly.

Accordingly, each issue will be dealt with with a different fixing method. 

How to drain the Asko dishwasher and get rid of the issue? Below you can find the solutions for the main issues affecting your appliance.

Of course, you must investigate thoroughly to apply the correct solution.

Alert: Remember that you should not try to fix the appliance yourself if it is still under warranty. Rather, call Asko support. 

The brand might send replacement parts, a technician to check and fix, or request a recall, so they send you a new appliance.

Solution #1: Unclog The Filters

The most probable cause of your dishwasher not draining is that some part responsible for draining is clogged.

That could be the filter, the drain hose/pipe, or any other part where debris can get stuck. 

unclog the filters

Thus, the logical first step is to eliminate any accumulated debris, right? That is what we are going to teach you.

Since it is an electronic appliance we are dealing with, it is important to take care when cleaning it.

  1. Check the bottom of the dishwasher for chunks of food and remove them;
  2. Ensure you remove any dirt you can see on the dishwasher’s interior;
  3. Place two cups of vinegar in a dishwasher-safe container on the lowest rack.
  4. Run a normal cleaning cycle

Using vinegar to wash with a cleaning cycle will eliminate plenty of dirt and debris, but that is not the end already.


  1. Turn off the appliance
  2. Open its door
  3. Lift off the filter cover
  4. Turn the filter counterclockwise
  5. Now you can remove the filter

Ensure you remove any removable filter components. After they are out, clean them with warm, soapy water. 

Let everything dry up, and put the parts back in the dishwasher. Then, when you turn it on the next time to clean your dishes, it should drain properly.

Tip: If you are a new dishwasher owner, you must know that cleaning like the above should be a regular procedure. That will prevent many troubles.

Solution #2: Replace The Solenoid

The solenoid kit controls the flow of water into the dishwasher.

As you might imagine, a defective solenoid will inevitably lead to variable issues regarding the water status in the device.

The one we are dealing with right now is draining, but it could also make the appliance overflow or not fill! 

Here is how you can replace the solenoid kit:

  1. Turn off the appliance’s power
  2. Shut the water supply
  3. Remove the access panel
  4. Locate the solenoid valve
  5. Disconnect the electric connections
  6. Uninstall the water supply lines
  7. Remove the valve

After you’ve removed the defective solenoid valve, it is time to replace it.

You can acquire a new one at any general retailer or specialized shop in your neighborhood. 

  1. Put the new solenoid valve in place of the old one
  2. Connect the water supply and electric wires
  3. Close the access panel firmly

Ensure that everything is in place, and turn the dishwasher again. It should work like a charm.

Alert: It is not recommended to try and repair the solenoid kit as it is a vital component of the dishwasher and may lead to further problems and failure.

Solution #3: Replace The Drain Impeller/Pump

While the solenoid kit/valve is vital for the good functioning of your dishwasher, it is not the only part that could be at fault.

Other parts fail too, and this time we will look at the drain impeller (also known as the pump).

As you can imagine, this component applies the force necessary for the water to drain. If it is defective, it is utterly impossible that the water will drain.

You must replace it with the following:

  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

As you can see, removing this part is very easy since it is underneath the appliance instead of inside it.

Therefore, replacing it is a breeze too. 

  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. Turn the device on to test
Note: The pump is truly a trivial part. You can easily do it at home without worrying about damaging any component when replacing it. 

Solution #4: Clean Or Replace The Drain Valve

Although many parts have similar names, the drain valve is another component of your dishwasher.

As the name indicates, it is one of the many parts responsible for the water flow on your appliance.

Perhaps the drain valve is causing trouble, and when that happens, you can clean it thoroughly.

Here is how:

  1. Unplug the dishwasher
  2. Turn off the water supply.
  3. Find the drain valve at the bottom of the dishwasher
  4. Remove debris or buildup with a brush or toothpick
  5. Flush out the valve with water

Alright, so you have cleaned it. After that, reassemble everything and test the dishwasher.

If it is still not draining, the valve might be defective. In that case, you must replace it. Buying a new drain valve is not a difficult task as it is very common.

Once you have a new one in your hands, do the following:

  1. Disconnect the old valve from the dishwasher’s plumbing
  2. Put the new drain valve in place 
  3. Put the dishwasher back in place
  4. Test it.
Note: If you don’t know how to shop for a new drain valve, you must take the old one to a nearby store. Some specialized sellers will help you buy the correct model.

Solution #5: Fix Small Wiring Issues

Finally, the draining issue might be caused by the wiring. When that happens, we advise you to only try to fix it yourself if the issues are small.

For example, if there are frayed wires, loose connections, or other visible damage, that looks easy to repair.

First, you must locate the wiring. Do the following:

  1. Locate the control panel
  2. Remove the screws/fasteners keeping them in place
  3. Remove the control panel
  4. Now you should see the wiring behind it

As you see the wires, investigate them carefully to check for anything off.

As we mentioned, frayed wires and loose connections are the most common issues that are easy to fix.

Here are the guidelines to fix them:

  • If there are loose connections, you can use pliers to tighten them. That will probably fix communication issues happening in the electric circuit.
  • When you find any broken wires, you can carefully splice them back together using wire nuts.
  • In the case of frayed wires, electrical tape is great for securing them and preventing further fraying.
Alert: If you investigate and find too much damage on the wires, you must call a professional. After all, wiring is delicate, and messing with it without the proper knowledge might damage it even more.

What We Learned

When you find your Asko dishwasher not draining, plenty of solutions can occur.

Devices like those are easy to fix even though the issues cause you a headache.

After the guide above, we are confident you will be able to wash your dishes again and see the water drained in no time.
