Reading a Miele F-Code
Miele appliances display an F followed by a number. The number maps to a functional area, drainage, water level, heating, or a sensor, which is why Miele is one of the easier premium brands to diagnose. That said, a code narrows the field rather than naming the exact part. A drainage code, for instance, could be a clogged filter or a failed pump, so the code plus a hands-on test is what leads to the right repair.
The Codes You Will See Most
| Code | Meaning | What We Check |
|---|---|---|
| F11 | Drainage fault, will not pump out | Filter, drain hose, drain pump |
| F12 | Water inlet fault | Inlet valve, supply, hose, filter |
| F13 | Water intake or fill issue | Inlet valve, flow meter, pressure |
| F14 | Drain or circulation pressure fault | Pump, sump, spray-arm circuit |
| F70 | Water-level or float fault | Anti-flood float, leak, level sensor |
| F78 | Circulation pump or flow fault | Circulation pump, wiring, control |
Exact wording varies by generation, but the pattern holds: the low F-numbers cluster around water in and out, while F70 and F78 point at the anti-flood system and circulation pump. On our hard water, scale is often the underlying reason these appear.
Clear the Drain Codes First
For a drainage code like F11 or F14, cleaning the filter and drain path and running a fresh cycle clears the fault surprisingly often. If the same code returns after that, the pump or a sensor is involved, and it is time to book rather than keep resetting.
