Error F14 on a Hotpoint induction hob typically indicates a problem with the touch control panel. Here are a few things you can try to fix this error:

1. Disconnect the power supply to the hob for a few minutes, then reconnect it and see if the error persists.
2. Try cleaning the touch control panel with a soft, dry cloth to remove any dirt or grime that may be causing the error.
3. If the problem persists, you may need to reset the touch control panel. To do this, you will need to locate the reset button, which is usually located underneath the hob or inside the control panel. Press and hold the reset button for a few seconds, then release it and see if the error persists.

If these steps don't fix the problem, it's possible that the touch control panel is faulty and will need to be replaced. You may need to contact a professional for this repair.
I hope this helps! Let me know if you have any other questions.

An E6 error code on a Belling induction hob typically indicates an issue with the power supply or the circuit board that controls the back two rings. Here are a few steps you can take to troubleshoot the issue:

1. Reset the hob: Try turning off the power to the hob for a few minutes and then turning it back on. This can sometimes reset the circuit board and clear the error code.
2. Check the power supply: Make sure the hob is receiving a stable and adequate power supply. Check the circuit breaker or fuse for the hob to ensure it is not tripped or blown.
3. Check the wiring: Inspect the wiring and connections for the back two rings to ensure they are not loose or damaged. Tighten any loose connections or replace any damaged wiring.
4. Contact a professional: If the issue persists, it may be a problem with the circuit board or control module. In this case, it's best to contact a professional technician or the manufacturer for assistance with repairs or replacement parts.

I hope this helps you resolve the issue with your Belling induction

Possibly a faulty induction plate.

Could be a power fault. But only the service manual gives the Rea reason. You also need the manual if you want to solve the problem

Try to do a search on the Internet, something like: Manual Bosch + your model number. I have usually had good luck finding a free download. Sometimes there are downloads also available directly on the manufacturer's website as well.

Check power supply at socket or meter box. Make sure that the circuit breaker hasn't tripped. Also, induction cooktops wont heat without induction cookware. They must be steel. Glass cookware wont work on an induction cooktop.

I have a KM5753 with FE31 and it remains after a breaker 1 minute re-set as per instruction booklet - anyone seen that one?
