miele dishwasher won't drain

While a dishwasher brand like Miele can offer superior performance, draining issues can still plague even this high-end name. We’ll review the most common causes for a Miele dishwasher not draining, like a dirty filter or clogged disposal, and how to solve the problem.

Miele Dishwasher Not Draining Properly? Here’s What to Do

Though puddles of dirty water in your dishwasher can be alarming, this problem typically has a DIY fix. We’ll troubleshoot some of the more common causes for a Miele dishwasher not draining and pinpoint simple solutions.

Dirty Miele Dishwasher Filter

A dishwasher’s filter screens out large food particles and debris that could otherwise clog the drain. However, without regular cleanings, the filter itself can become clogged, prohibiting water from draining properly.

Dishwasher cleaning tips include rinsing the filter on a monthly basis to prevent clogs. Here’s how to clean a Miele dishwasher filter in 7 simple steps:

  1. Remove the dishwasher’s lower rack.
  2. Turn the filter handle counter-clockwise and lift up to remove the filter assembly.
  3. Rinse the filter under running water in the sink, scrubbing the outside with a soft bristle brush as needed.
  4. Open the filter flap by pushing in the plastic clips on either side. Rinse the open filter under running water to remove additional debris.
  5. Close the filter flap until the clips click in place.
  6. Replace the filter and turn the handle clockwise to lock it in position.
  7. Return the lower rack to the dishwasher.

Drain Hose is Clogged or Bent

Your Miele dishwasher drain hose connects the drain pump to your garbage disposal, air gap, or sink drain to deposit dirty water. Given the position of this hose under the sink or behind the dishwasher, it can bend and prevent water from draining. Check the hose for bends or kinks, gently straightening it if needed.

In other instances, food particles can clog a drain hose and prevent proper drainage. Follow these steps to remove drain hose blockages:

  1. Consult your user manual to access the location of your model’s drain hose.
  2. Place a towel under the hose and disconnect it from the drain pump.
  3. Blow through the hose to determine if a clog prevents air from passing through.
  4. Carefully remove clogs with a screwdriver or straightened coat hanger before reconnecting the hose to the drain pump.

If the clog cannot be reached through the drain pump connection, replace the hose and attempt to reach it via the disposal’s connection. If the blockage still cannot be reached the drain hose should be replaced.

Garbage Disposal is Clogged

If you have a Miele dishwasher not draining water, it can also be due to a clogged garbage disposal. Since a dishwasher and disposal typically share a common drain, food particles that remain in the disposal can prohibit a dishwasher from draining.

Before beginning a wash cycle, run the disposal to clear it of any remaining food particles. This will help ensure that water from the dishwasher can flow freely through this shared drain.

What does F11 mean on my Miele dishwasher?

Is your Miele dishwasher not draining F11 error code displayed? F11 on a Miele dishwasher means that there is water in the base pan. This error code will display if the dishwasher is not draining properly. To fix this problem, you will need to check the drain hose for any clogs or blockages. You may also need to clean the base pan and drains to remove any debris build-up. If you still have problems, you can contact a Miele service technician for further assistance.

How do I make my Miele dishwasher force drain?

If your Miele dishwasher isn’t draining properly, you may need to force it to drain. To do this, first, make sure that the dishwasher is turned off, and the water supply is shut off. Then, open the door and remove any items that are blocking the drain. Next, locate the drain hose and disconnect it from the dishwasher. Once the hose is disconnected, you should be able to see a small hole near the bottom of the dishwasher. Place a small funnel into this hole and pour a gallon of hot water into the funnel. This will help to break up any debris that may be causing a blockage. Finally, reconnect the drain hose and turn on the dishwasher. The forced draining should help to clear any remaining debris and allow your dishwasher to function properly.

What does F13 mean on my Miele dishwasher?

The F13 error code on a Miele dishwasher indicates that there is an issue with the water inlet valve. This valve controls the flow of water into the dishwasher; if it is not functioning properly, the dishwasher will not be able to fill with water. The most common cause of this error code is a buildup of mineral deposits on the valve, which can cause it to become blocked or stuck. To fix this problem, you will need to clean the water inlet valve and the surrounding area. If the problem persists, you may need to have a professional Miele dishwasher technician replace the water inlet valve.

If your Miele dishwasher won’t drain even after these troubleshooting tips then it’s possible the drain pump has malfunctioned, requiring professional Miele dishwasher repair and part replacement. DesertTech can help solve the problem and address any other high-end dishwasher repair.
