How to Fix a Miele Dishwasher That Won’t Drain

Finding water at the bottom of your Miele dishwasher means that the drain valve or pump is blocked. This can result in flooding in your dishwasher and cause it to function improperly. As a result, you’re faced with dirty dishes, food debris floating around and possibly water leaks on your floor. In addition, if there’s a hard object obstructing the valve or pump, you can face more serious technical issues further down the road. There is good news though. These Miele dishwasher problems can sometimes be solved on your own while in other cases, an expert may need to be called in. But before you do that, here are some guidelines as to how to unblock a Miele dishwasher.


Miele: troubleshooting a dishwasher

When your Miele dishwasher is not draining, you’re stuck with a non-functioning appliance, dirty dishes and a headache. But it doesn’t have to be this way. There are some tips and tricks you can do when your dishwasher won’t drain. Here’s what you can do on your own before calling in an expert:

  • It’s highly recommended that you disconnect the dishwasher from the mains power at the wall. This is an important safety precaution that will help keep you and the members in your home safe. 
  • Be aware of water leaking out of the dishwasher and be sure that you do not slip and fall. Having a cloth nearby to soak up water on the floor might be a good idea. 
  • Next, remove the dish tray so that you have access to the spray arm and filter of your Miele dishwasher.
  • Remove the spray arm (if possible). In some cases, it simply clicks out of place. In others, you may simply need to rotate it so that you have access to the filter. 
  • Once this has been done, remove the filter combination at the bottom by turning it in an anti-clockwise direction to release.
  • Make sure to remove any particles around it. You also need to clean the primary filter and run it under a tap of water because if it’s clogged, this could be the reason why your dishwasher is not draining properly. 
  • Scoop any water that’s floating around out of the cabinet and place it in a small container.
  • Remove the non-return valve. You can do this by pressing the catch inwards. Remember that dishwashers operate on the same basic principles and that most parts have been designed in such a way as to ensure easy maintenance. 
  • Rinse the non-return valve under water to remove blockages and any foreign objects.
  • Ensure the middle ball inside the non-return valve is moving freely.
  • The drain pump is located under the non return valve – check it for any obstructions. If any water pops out at this stage, do not worry. This is normal. 
  • Turn the drain pump impeller to check for any more obstructions.
  • Then, make sure you put the non-return valve back in place followed by the filter and spray arm. 
  • After this, be sure to place the dishwasher tray back in place. 
  • You can close the dishwasher door and reconnect the power at the mains.
  • Your dishwasher should now be ready to use.


The bottom line

It can sometimes happen that due to debris, glass and even labels or other obstructions, your Miele dishwasher can not drain the water inside properly. To resolve this issue is not difficult and in most cases, you’ll be able to handle this yourself. The process is simple and involves removing and unclicking certain parts of the dishwasher so that you can clean the area better.
