What F09 actually means
The hob has lost a sensible reading from the temperature sensor built into one of its induction coils, so it shuts that zone down rather than heat blind.
Each induction coil has its own temperature sensor watching how hot the coil and the glass above it are getting. When the control board sees a reading that is out of range or missing altogether, it treats the sensor as failed, drops into a protective state and shows the fault instead of heating. Because the hob can no longer tell how hot it is, it will not allow that zone to run.
What F09 looks like on a Montpellier hob
Most people find this page having searched for what the machine is doing rather than the code itself. On a Montpellier hob, F09 usually shows up as one or more of these:
- Hob not draining
- Water left in the machine at the end of the cycle
- Stops mid-cycle full of water
- Standing water in the bottom
- Not heating up
- Takes ages to get to temperature
- Cuts out part way through cooking
- Noisy fan
Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.
What usually causes it
- Failed temperature sensor on the induction coil under the affected zone
- Sensor wiring or plug to the control board come loose or damaged
- Water or spillage that has got past the glass into the coil area
- Control board fault misreading a sensor that is actually sound
- Heat damage after prolonged use with an empty or badly fitting pan
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the hob off at the wall for a minute, then switch back on — a one-off glitch after a boil-over sometimes clears
- Make sure the glass is dry and the underside of the hob is not being blocked, for example by anything stored in the cupboard or drawer directly beneath it
- Check whether the fault affects only one cooking zone or all of them, and note which — that saves an engineer time
- Let the hob cool right down before trying again if it has been running hard

F09 means the same thing on all 2 of these models. If yours is not listed, the explanation above still applies — the code is set by the control board, not the model number.
