Miele Error Codes Explained

Miele publishes clear F-codes, which makes diagnosis efficient. Here is what the common dishwasher and oven codes mean, which you can often clear yourself, and which need a technician.

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

CodeMeaningWhat We Check
F11Drainage fault, will not pump outFilter, drain hose, drain pump
F12Water inlet faultInlet valve, supply, hose, filter
F13Water intake or fill issueInlet valve, flow meter, pressure
F14Drain or circulation pressure faultPump, sump, spray-arm circuit
F70Water-level or float faultAnti-flood float, leak, level sensor
F78Circulation pump or flow faultCirculation 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.

Seeing a Miele F-Code?

Book a diagnosis with a brand-focused technician. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval.

Frequently Asked Questions

What Does F70 Mean on a Miele Dishwasher?
F70 is a water-level or float fault. The dishwasher senses a level problem, often from the anti-flood float being triggered by a small leak, a stuck float, or a sensor fault. Check for water in the base pan first; if F70 returns, it needs a technician to trace the leak or float.
Can I Clear a Miele F-Code Myself?
For drainage codes like F11, cleaning the filter and drain path and running a fresh cycle often clears it. Codes tied to leaks, heaters, or sensors will keep returning until the part is repaired. If the same code comes back, book a diagnosis.
Does Hard Water Cause Miele Fault Codes?
Indirectly, yes. Scale from hard Front Range water clogs filters, coats heaters, and stresses pumps and valves, which leads to drainage and heating faults over time. Regular descaling and keeping the softener salt topped up reduce these code events.
