How a Miele appliance reports a problem
Miele appliances differ in how much they tell you. Dishwashers and washers carry a rich set of F-numbers; dryers, ovens and induction cooktops have a thinner set of service codes; and refrigeration, wine reserves and gas rangetops have no consumer code table at all, so they are diagnosed from symptoms. Reading the right signal is the fastest route to an accurate Miele repair, because each F-code points at a specific part — a sensor, a pump, a heater, a door lock, a flow meter or the control board — while a symptom points at airflow, the seal, the supply or a mode left running. This page explains the genuine signals Miele uses across the range; every appliance type also has its own detailed breakdown in the error codes library.
Dishwasher F-codes (the richest set)
The G dishwasher is the most code-driven Miele appliance. F11 is a drainage problem, F12/F13 water intake at the start and end of a step, F14 the heater pressure-switch intake and F15 a hot-water inlet problem. F18/F19 are flow-meter problems, F24/F25/F26 heating and boiling-protection, and F32/F33/F36 the door auto-close, lock and switch. F70 is the Waterproof System float — water in the base — while F86 salt-lid, F87 water softener and F88 turbidity sensor are at the milder end. The dishwasher error codes page lists the full set.
Washer service error codes
The W1 washer pairs F-numbers with the plain-English messages Miele shows owners. F10 is a water-inlet problem, F11 a drainage problem, F15 a hot-water intake issue and F16 excess foam. F20 is a heating problem, F34/F35 the door failing to lock or unlock, F56 a final spin that is too low, and F138 the Waterproof flood float — shown as “Waterproof system activated”. F92 is the hygiene / mould prompt. See the washer error codes page for the full list.
Dryer, oven and cooktop service codes
The T1 dryer keeps it simple: F50 control, F53 motor tacho, F55 not dry after 180 minutes and F66 the airflow / ventilation problem — the most common — alongside plain messages such as “Clean out airways” and “Empty container”. Ovens and ranges use service F-codes for the temperature sensor (F05/F06), the pyrolytic door lock (F32/F33) and the meat probe (F54), but most oven complaints are symptom-led. Induction cooktops show a brief F when sensors are covered, F1–F4 at calibration, and a technician-level FE family for deeper problems; H residual heat and the pan symbol are normal states, not errors.
The categories diagnosed by symptom
Three Miele categories have no consumer error-code table and are read entirely from behavior. Refrigeration shows a temperature or door alarm, a flashing display, an ice-maker indicator on older units, or demo mode — a showroom setting that disables cooling by design and is the first thing to rule out when a fridge “won’t cool”. Wine reserves show a temperature or door alarm and a generic _F problem. Gas rangetops have no display at all, so a burner that will not light, clicks without sparking or burns yellow is the diagnostic itself. The per-type pages walk through these symptom-led checks in detail.
When to reset and when to call
For many problems the homeowner step is the same: power-cycle the appliance — switch it off at the wall or the breaker for a minute — and watch the panel. Door locks, demo mode, a salt or rinse-aid warning, a Flow-style “clean out airways” prompt and a one-off alarm usually clear or resolve with simple maintenance. A persistent sensor or board failure, a pump or motor code, a drainage failure, a Waterproof / flood trip or a cooling problem that is not demo mode calls for an experienced technician with genuine Miele parts.
