Miele Dishwasher Error Code F5

F5 on a Miele dishwasher indicates a water drain fault, meaning the machine was unable to empty water from the tub during a drain cycle. The dishwasher stops the cycle to prevent problems caused by standing water. This fault typically points to a blockage in the filter, drain hose, or household plumbing, or to a problem with the drain pump itself.

You should not continue running the dishwasher while F5 is active. Standing water in the tub can harbor bacteria, and repeatedly forcing the machine through cycles with a drain fault can stress the pump motor and other components. Address the underlying cause before resuming normal use.

A reset may temporarily clear the F5 code and allow the machine to start a new cycle, but the fault will return if the underlying drainage problem has not been resolved. Resetting without fixing the root cause can also result in water remaining in the tub, which can cause odors and potential damage. Always investigate and correct the drain blockage or component failure before relying on a reset.

Many F5 faults are DIY-repairable. Start by removing and thoroughly cleaning the filter assembly and checking the sump for debris. Then inspect the drain hose for kinks or clogs and confirm the sink drain or garbage disposal connection is clear. If cleaning does not resolve the fault, diagnosing and replacing the drain pump or control board components may require more advanced repair skills and tools.

If the issue is simply a clogged filter or drain hose, the repair costs nothing beyond your time. A replacement drain pump for a Miele dishwasher typically ranges from roughly $60 to $180 for the part alone, with professional labor adding $100 to $250 depending on your area. Control board repairs or replacements are generally more expensive, often ranging from $200 to $500 or more for parts and labor.
