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 combination.
  3. Rinse the filter combination under running water, 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

A Miele dishwasher not draining can also be due to a clogged garbage disposal. Because 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.

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