Miele publishes numeric fault codes, and F11 is one of the clearest: the machine has detected a drainage problem. Water stays in the tub, the program stops, and the control waits rather than attempting another fill. On G 5000, G 6000 and G 7000 series Miele dishwashers, F11 is a mechanical blockage far more often than an electrical failure.
What F11 Is Measuring
Miele monitors the drain phase closely. When the water level fails to drop within the expected time, the control assigns F11 to flag that drainage has not completed. It is a protective stop that keeps the next intake from overfilling a tub that is still holding water.
The precision of the Miele code set is helpful here. F11 sends us straight to the drain path, so the diagnosis starts with the filter and pump rather than a broad hunt.
Where Miele F11 Usually Originates
- The triple filter clogged with fine food residue
- The drain pump impeller jammed by a fragment of glass or a fruit stone
- The non-return valve stuck closed with grease
- The drain hose kinked or its check flap blocked
- A sink waste or air gap that has silted up over time
The Miele-Specific Diagnosis
We remove and clean the triple filter, then open the drain pump cover to inspect the impeller, which on Miele is reached from inside the tub. We confirm the non-return valve moves freely and flush the drain hose. Miele pumps are robust, so we only test the winding and the control output once the mechanical path is proven clear.
Because these machines are built to a long service life, most F11 calls end with a cleaned path and a healthy pump rather than a replacement.
Miele Drainage Code Reference
| Code | Meaning | First Action |
|---|---|---|
| F11 | Drainage fault, water not clearing | Clean filter and pump, flush hose |
| F12 | Water intake fault | Check inlet valve and supply |
| F13 | Heating circuit fault | Test flow heater and thermostat |
| F70 | Float or water-level sensor fault | Inspect base for leaks and float |
