The F11 code means your dishwasher is not draining properly. In most service calls, I find a piece of glass or a small bone stuck in the pump impeller or a clogged non-return valve. Start by cleaning the filters and checking the pump area for obstructions.
Ignore F11 long enough and you'll end up with a burned-out pump motor or water on your kitchen floor. I've seen people leave it for a week thinking it'll clear itself. It won't. The good news is that 80% of the time this is literally a $0 fix you can knock out in 20 minutes. Pull the filters, check the pump, done.
Miele dishwashers are honestly some of the toughest machines I work on, but F11 is still one of my most common service calls. These things are built to last 20 years, but the drainage system is so precisely engineered that a single cherry pit or shard of broken glass will stop it cold. Most of the time you don't even need parts. Just debris you can pull out with your fingers.

Symptoms You May Notice
There's an inch or two of standing water sitting at the bottom of the tub after the cycle ends and you open the door.
You can hear the drain pump humming and running, but the water level just never drops.
The cycle stops partway through, the machine beeps several times, and F11 shows on the display.
You run a second cycle hoping it'll sort itself out, and the same thing happens again at the same point in the program.
Slight sour or stagnant smell from the machine because water's been sitting in the sump.
Can you reset a Miele dishwasher to clear the F11 code?
After you've cleared the blockage, press the Power button to turn the machine completely off. Wait about 30 seconds, then power back on and start a short rinse cycle to test. If F11 comes back right away, the drain sensor still detected standing water, so re-check the non-return valve and pump area. A successful drain will clear the code on its own.
Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Frequently Asked Questions
Can I reset the Miele F11 error by unplugging it?
You can, and the display will clear. But the second you run it again and it tries to drain, F11's coming right back. Unplugging doesn't fix anything, it just wipes the code temporarily. You've got to actually deal with the blockage in the filters or pump. Think of the code as your machine telling you something's wrong, not the problem itself.
Why does my dishwasher have water at the bottom after the cycle?
That's exactly what triggers F11. The control board watches how fast the water level drops during the drain phase, and if it doesn't drop fast enough, it throws the fault. Standing water is almost always caused by a jammed impeller or a non-return valve that's not seating properly and letting water drain back in. Start with the filters and valve check before you assume it's a pump failure.
Where is the non-return valve located on a Miele?
It's in the sump at the bottom of the wash cabinet. Once you've pulled out the filter assembly, look to the left side of the sump area for a small metal wire clamp that looks kind of like a hairpin. Flip that clamp up and the whole valve assembly pulls straight out. It's not hidden or hard to get to once the filters are out of the way, maybe 30 seconds to remove.
Is the F11 error code common on older Miele models?
Super common. Honestly it's one of the top three calls I get for Miele dishwashers across all ages and model lines. And here's the thing, it's not really an age issue. I've gotten F11 calls on brand new machines because a piece of bone or glass got through and into the pump housing. The drainage system is precise, which is part of why these machines last so long, but that same precision means small debris causes big problems.
Does a clogged garbage disposal cause an F11 error?
Yes, absolutely. This one catches people off guard. If you just installed a new disposal and forgot to knock out the drain plug on the dishwasher port, or if the disposal inlet is packed with gunk, your dishwasher physically cannot push water out. The pump's running fine, the valve's fine, but there's nowhere for the water to go. Always disconnect the drain hose at the disposal end and check that connection if the dishwasher itself looks clean.
How much does it cost to fix an F11 error on a Miele dishwasher?
If it's just a clogged filter or debris in the pump, literally $0. That's most cases. A new non-return valve runs about $15-20. If you need a new drain pump, you're looking at $60-80 for the part plus labor if you're not doing it yourself. A service call for this is usually $150-250 depending on your area. Honestly, try the DIY steps first. Miele's drainage system is designed to be user-serviceable and you've got a solid shot at fixing this yourself.
How do I know if it's the pump motor versus just a blockage?
Listen carefully when the machine tries to drain. If you hear a humming noise but no water movement, you've probably got something jammed in the impeller. If you hear nothing at all from the pump area, the motor might be dead. Use a multimeter to check the motor windings, you want 200-400 ohms. Get infinity or OL? Dead motor, you need a new pump assembly.
