Miele Dishwasher F11 Error

When a Miele dishwasher posts F11, it is telling you the water did not drain out in time. The machine expects the tub to empty on schedule, and when it does not, it stops the cycle to keep water from backing up. The good news is that F11 is one of the more approachable faults, because the most common causes are a clogged filter and a blocked drain hose, both of which you can check.

What F11 Actually Means

F11 is a drainage timeout. The drain pump ran but the sensor never confirmed the water left. That points to a restriction somewhere in the drain path or to a pump that is not moving water. It is not a random glitch, so the path forward is to find and clear the restriction rather than just reset.

Work Through the Drain Path

Turn the dishwasher off. Remove the filter assembly at the bottom of the tub and rinse it thoroughly, clearing any food or debris in the sump beneath it. Then check the drain hose where it connects to the sink drain or disposer for a kink or a clog. Clear any standing water, reseat the filter, and restart.

Cause	How It Shows	Our Fix
Clogged filter or sump	Standing water, F11	Clean filter and sump
Kinked or blocked drain hose	Slow or no drain	Clear or re-route hose
Failing drain pump	F11 returns after cleaning	Test and replace drain pump
Blocked disposer knockout	New install, will not drain	Clear the knockout plug

What You Can Try, and Where to Stop

Cleaning the filter and clearing the hose are safe and often enough. If F11 returns after that, the drain pump or the water-path sensor is the likely cause, and testing or replacing the pump is a technician job that comes with a warranty on the repair.

Frequently Asked Questions

What Does F11 Mean on a Miele Dishwasher?

F11 is a drainage fault. The dishwasher started a drain and the water did not leave within the expected time, so it halts to avoid overfilling. The usual causes are a clogged filter, a blocked or kinked drain hose, or a failing drain pump. Clearing the filter is the first step.

How Do I Clear a Miele F11 Error?

Turn the dishwasher off, remove and rinse the filter at the bottom of the tub, and check the drain hose for a kink or clog where it meets the sink drain. Clear any standing water, then restart. If F11 comes back, the drain pump or the water-path sensor likely needs service.

Can I Keep Using a Miele Dishwasher with an F11 Error?

No. F11 stops the cycle to prevent water from backing up, so running it again without clearing the cause usually just repeats the fault and can leave standing water. Clear the filter and hose first, and if it persists, book service before running it again.
