Miele Dishwasher Error Code F11

F11 on a Miele dishwasher indicates a drainage fault, meaning the machine detected water in the tub that was not successfully drained within the expected time. It can also appear when heater relay K1/1 fails to activate following an F51 check, making it possible for an electrical issue to trigger this code even when the drain hose and pump are functioning correctly. Standing water visible in the bottom of the tub typically confirms an active drainage problem.

You should not continue running the dishwasher while F11 is active. Standing water in the tub can harbor bacteria and may spill when the door is opened. Running additional cycles without resolving the drainage fault can also stress the pump motor and potentially worsen the underlying problem.

Repair costs vary depending on the root cause. Clearing a blocked hose or cleaning the filters costs nothing beyond your time. If the drain pump needs to be replaced, parts and labor typically range from $150 to $400 depending on your location and the specific model. A control board or relay fault can push costs higher, potentially ranging from $300 to $600 or more for parts and professional labor.

In many cases, yes. Start by inspecting the drain hose for kinks or blockages and confirm it is not inserted too deeply into the standpipe. Then remove and clean the filters and sump area inside the dishwasher tub. If those steps do not resolve the error, checking the drain pump for jammed debris is also something a confident DIYer can attempt, though motor replacement and control board diagnosis are better left to a qualified technician.

A reset may clear the fault code temporarily, but if the underlying cause has not been corrected, the error will return as soon as the machine attempts to drain again. Resolve the drainage issue first, then reset the appliance. If the code reappears immediately or on the next cycle, further diagnosis of the pump, hose, or relay is needed.
