On Miele dishwashers, F11 is a drainage fault (filters, drain pump, hose), F12/F13 a water intake fault (closed valve or clogged inlet filter), F14 the heater pressure switch, F15 overfill, F18 the flow meter or inlet valve, F70 the Waterproof system after water reached the base, and F78 the circulation pump. Newer models show a text message instead of an F-number. Clean the filters and check the valve first.

| Code | What it means | What you can do |
|---|---|---|
| F11 | Drainage fault | Clean filters; check the drain pump cover and hose. |
| F12 / F13 | Water intake fault | Open the valve; clean the inlet filter. |
| F14 | Heater pressure switch fault | Technician repair. |
| F15 | Overfill | Technician repair (often a stuck sensor). |
| F18 | Flow meter / inlet valve fault | Technician repair. |
| F70 | Waterproof system activated — water in the base | Find the leak; the base must dry; call if it repeats. |
| F78 | Circulation pump fault | Technician repair. |
Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Code came back after these checks? That means a part has failed — let a technician confirm it before parts are guessed.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
Yes — newer models describe the fault in words; causes are the same.
Yes, whenever they're available.
