Miele Error Code F11

What F11 Means

Miele dishwashers use numeric F-codes to flag specific faults, and F11 typically points to something in the drainage system — either the drain pump isn't running as it should, or the machine isn't sensing water actually leaving the tub. It's worth noting that Miele's exact F-code definitions can shift slightly between model generations, so treat F11 as a strong pointer toward a drainage issue rather than an exact, universal diagnosis. A technician will confirm the precise fault against your model's service documentation.

Likely Causes

• A clogged filter assembly at the base of the tub
• A kinked or blocked drain hose
• A drain pump that's jammed or beginning to fail
• A blocked air gap or garbage disposal knockout plug on the connected sink drain

What You Can Check Safely

Remove and clean the filter assembly at the bottom of the tub — this is a routine task on Miele dishwashers and your owner's manual will show the release mechanism for your specific model. While it's out, check for food debris or buildup. You can also check the drain hose where it's visible behind or under the machine for kinks. Don't attempt to open the pump housing or access the machine's internal components yourself.

When to Call a Technician

If the filter is clean and the hose is clear but F11 keeps appearing, the drain pump likely needs professional diagnosis. Miele dishwashers use specialized parts and tighter-tolerance assemblies than many mainstream brands, so this is a case where it's worth having a technician confirm the fault rather than guessing.
