Miele cooktops
German induction with a factory-documented FE dialect.
Miele induction cooktops speak a precise language: an F on a zone display for a soiled control field, FE codes with numbers for electronics faults - and Miele's own service literature maps them to specific boards and sensors. Gas KM tops stay mechanical. Either way, the diagnosis follows the factory's book, not the internet's.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Induction
KM 7000 series
Current US induction tops, up to the full-surface flagships with PowerFlex zones.
Gas
KM gas cooktops
Sealed-burner gas tops with electric ignition - no codes by design.
Modular
SmartLine / CombiSets
Element modules that pair induction, gas and specialty units in one run.
Legacy
KM 5000-6000 induction
Earlier platforms like the KM 5773 - the generation Miele's public service manuals document in detail.
Start with the symptom
Common Miele cooktop problems
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Zones
Zone won't detect the pan
Pan material and diameter first - induction is honest physics before it is electronics.
Symptom
Whole top dead
Supply, then filter and control electronics - the FE 30/31 path with a meter.
Zones
One zone weak or cycling
Power module and zone sensor - localized by the code when present.
Burners
Gas burner clicking on
Moisture and cap seating - dry and reseat before parts.
Surface
Cracked glass
Stop using the top; ceran replacement is quoted honestly against unit value.
Symptom
Boost cuts out early
Thermal management doing its job versus a failing sensor - split by testing.
Series and model numbers
Miele cooktop series we service
Miele identifies machines by model and fabrication number - and on induction tops, the generation decides which fault-code table the service data uses.
Induction
KM 7xxx
Model numbers
KM 7740, KM 7897 FL
What to note
FL/FR suffixes mark frame style - the full number decides electronics.
Legacy induction
KM 5xxx-6xxx
Model numbers
KM 5773, KM 6357
What to note
The FE-code generation with published technical documentation.
Gas
KM gas models
Model numbers
KM 3465, KM 3475
What to note
Igniters, valves and caps - direct diagnosis, no display.
Model label
Where to find your Miele model number
The data plate is on the underside of the cooktop, reached from the cabinet below; Miele also ships a duplicate data sticker with the documents folder. The fabrication number is what service and parts run on. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
Miele cooktop alerts & indicators
For any message not shown, use the manual for the exact model rather than a generic list.
Message / alert
F flashing on a zone display
What it means
Miele's official guidance: the control field is soiled or an object is sitting on it - not a component fault.
Safe check
Clean and dry the control area, remove objects, switch the top back on; an F that survives a clean panel merits the visit.
Miele diagnostics
Miele cooktop error codes, decoded.
The FE table comes from Miele's own technical documentation for its induction platform, with FE31 additionally confirmed on Miele USA's support portal. Gas KM tops publish no codes - and none are invented for them.
Not a fault · F on a zone display
Control field soiled or covered
What it commonly means
Officially documented by Miele: liquid, a cloth or an object on the sensor field blocks the controls.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Clean first - the honest non-repair; persistent F moves to touch-electronics diagnosis.
Error code · FE 01-FE 25
Sensor field soiling / evaluation
What it commonly means
Per Miele's technical documentation, FE plus a number in the timer display flags soiling or faults in the sensor evaluation circuits.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The control field and selection electronics are inspected and tested per the factory procedure.
Error code · FE 30
Supply voltage fault
What it commonly means
Factory documentation: secondary voltage too high - a connection or supply problem, with a continuous beep.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The supply and terminal allocation are verified before any electronics are blamed - frequently an installation fault.
Error code · FE 31
Missing phase / power electronics
What it commonly means
Miele USA lists FE31 as a technical fault requiring service; the service manual traces it to a missing supply phase or power-electronics fault.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
Supply phases and the bridge terminals are checked, then the power electronics tested per the manual.
Error code · FE 43 / FE 44 / FE 45
Power electronics temperature sensor
What it commonly means
Factory documentation: the NTC on a power module's heat sink failed - left, right or middle module by number.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The named power module is tested and replaced - the code localizes the board for us.
Error code · FE 51-FE 55
Burner PTC sensor
What it commonly means
Per the service manual: the temperature sensor for one of the cooking zones is defective.
Safe owner step
Photograph the code and the model label, and press reset once. A single power interruption at the breaker is reasonable if safely accessible - do not repeat it.
What repair typically involves
The zone's PTC is measured against factory resistance values and replaced.
Any other code or behavior
Meanings vary by series and year
Why we do not guess
Miele products span several control generations; the same characters can mean different things on different series. The complete model number fixes the definition.
What to capture
Photograph the full display and the model label, and note what the appliance is doing.
Next step
The $99 diagnostic visit confirms the actual fault before any repair is authorized. Book a visit or call (619) 877-6701.
Preventive service and owner care
Miele cooktop maintenance

Helpful answers
Miele cooktop service questions
Clear preparation makes a service request easier to evaluate.
Do you offer same-day Miele cooktop repair in San Diego?
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Does the $99 residential diagnostic fee always apply?
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
What warranty comes with a repair?
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
Can a symptom alone identify the failed part on a Miele cooktop?
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
What does the F on my Miele induction zone mean?
Officially: the control field is soiled or covered - liquid, a cloth, a pan edge. Clean and dry the panel and switch the top on again; a persistent F is a touch-electronics visit.
What is an FE code with a number?
Miele's electronics dialect - the number localizes the fault, from sensor soiling (FE 01-25) to specific power modules (FE 43-45). We diagnose per the factory table.
Where is the model number?
On the underside of the top, from the cabinet below - or on the duplicate data sticker in your documents folder. The fabrication number matters most.
Do Miele gas cooktops show error codes?
No - they are mechanical with electric ignition, and diagnosis is direct: electrodes, valves, caps.
Is a dead Miele induction top worth repairing?
Usually yes - the FE dialect localizes faults to specific modules, which makes repairs targeted rather than exploratory.
