Miele Dishwasher: not draining
What is this symptom?
If your Miele dishwasher is not draining, you're likely facing standing water at the bottom of the unit. This issue can be accompanied by error codes like F11, or you might hear unusual humming or gurgling sounds during the drainage process. Common causes include a clogged drain filter, a blocked drain hose, or a malfunctioning drain pump. Identifying the problem early can help avoid further complications.
