What F11 Is Telling You
When a Miele dishwasher reaches the end of a wash and needs to drain, the drain pump has a set window to push the water out. If the machine still senses water after that window, it stops and shows F11. The code is precise about the symptom, the water did not leave, but not about the cause, which can sit anywhere along the drain path.
In most Cherry Hills Village kitchens the cause is a restriction rather than a failed pump. The base filter fills with food debris, the drain hose kinks behind the cabinet, the air gap on the counter clogs, or the disposal connection is blocked. Each of these slows drainage enough to trip F11.
Where the Restriction Usually Is
| Check | What We Find | Fix |
|---|---|---|
| Base filter | Packed with debris and grease | Clean and reseat the filter |
| Drain hose | Kinked or clogged behind cabinet | Reroute or clear the hose |
| Air gap | Blocked counter air gap | Clean the air gap |
| Disposal port | Knockout plug still in place | Remove the plug, clear the port |
| Drain pump | Impeller jammed or motor failed | Free the impeller or replace the pump |
Clearing F11 and When to Call
Start with the base filter: twist it out, rinse it under hot water, and clear the sump beneath it, then run a rinse to see whether the water clears. Check that the drain hose is not kinked and that the air gap and disposal connection are open. These steps resolve a large share of F11 codes without any part.
If F11 returns after the drain path is clear, the pump itself needs testing. We check it for continuity and free rotation, clear the check valve, and replace the pump with a model-specific Miele part under our warranty when it has failed.

Frequently Asked Questions
How Do I Fix a Miele F11 Error Myself?
Begin with the base filter and sump: remove and rinse the filter, clear any debris, then check the drain hose, air gap, and disposal connection for blockages. Running a rinse afterward shows whether the water now clears. If it does not, the pump needs testing.
Does F11 Mean My Miele Drain Pump Is Broken?
Not necessarily. F11 means the water did not drain in time, which is most often a restriction in the filter, hose, or air gap. A failed drain pump is only one possible cause, and we confirm it by testing before replacing it.
Why Does F11 Keep Coming Back?
A recurring F11 means the drain path is still restricted or the pump is failing. If cleaning the filter and hose does not resolve it, the check valve may be stuck or the pump may be weak, both of which we diagnose and repair.
