Miele Dishwasher Troubleshooting Steps

Water Not Draining Properly

  1. Check the Drain Hose
  2. Inspect the Air Gap
  3. Clear the Filter

Check the Drain Hose

Inspect the drain hose for any kinks or blockages. Make sure it is properly connected to the sink drain or garbage disposal. If you find any obstructions, carefully remove them and ensure the hose is free from bends or restrictions.

Inspect the Air Gap

The air gap prevents wastewater from flowing back into your dishwasher. Check if it is clean and free from debris. Clean it if necessary and ensure it is properly installed.

Clear the Filter

A clogged filter can hinder proper drainage. Remove the filter from the dishwasher and clean it under running water. Make sure there is no residue or debris that could impede water flow.

Dishes Not Getting Clean

  1. Check the Spray Arms
  2. Clean the Filters
  3. Use the Correct Detergent and Rinse Aid

Check the Spray Arms

Inspect the spray arms for any blockages. Remove them from the dishwasher and rinse them under warm water to remove any debris. Ensure that the spray arm nozzles are clear and unclogged.

Clean the Filters

Dirty filters can affect the cleaning performance of your dishwasher. Remove the filters and rinse them under running water. Use a soft brush to gently remove any stubborn particles. Make sure the filters are completely dry before reinserting them.

Use the Correct Detergent and Rinse Aid

Ensure that you are using high-quality dishwasher detergent and rinse aid suitable for your Miele dishwasher. Follow the manufacturer’s instructions and use the recommended amount for optimal cleaning results.

Dishwasher Not Starting

  1. Check the Power Supply
  2. Verify the Door Is Properly Closed
  3. Reset the Dishwasher

Check the Power Supply

Ensure that the dishwasher is properly connected to a functioning power supply. Check the power cord for any damage or loose connections. If necessary, plug the dishwasher into a different outlet to eliminate any power supply issues.

Verify the Door Is Properly Closed

Make sure the dishwasher door is securely closed. If it is not latched correctly, the dishwasher will not start. Double-check the alignment of the door and ensure there are no obstructions preventing it from closing properly.

Reset the Dishwasher

Sometimes, a simple reset can resolve the issue. Turn off the dishwasher, unplug it from the power source, wait for a few minutes, and then plug it back in. This can help reset any internal electronics and restore normal operation.

Unpleasant Odor from the Dishwasher

  1. Clean the Interior

Clean the Interior

Thoroughly clean the interior of your dishwasher. Remove any food particles, debris, or residue that may have accumulated. Pay special attention to the door gasket, racks, and spray arms.

Run an Empty Cycle with Vinegar

Fill a dishwasher-safe bowl with white vinegar and place it on the top rack of your empty dishwasher. Run a hot water cycle to help eliminate any lingering odors and freshen up the dishwasher.

Check for Food Residue in the Filter

Inspect the filter for any food residue that might be causing the odor. Clean the filter thoroughly under running water and ensure it is free from any debris.
