Frequently Asked Questions
Bosch induction hob E6 error during summer only — why?
In hot ambient conditions, the hob electronics heat up faster and the cooling fan has less thermal headroom. E6 in summer is often an installation issue — verify the ventilation gap meets the minimum requirement.
Bosch induction hob makes a loud noise under the counter — is that the fan?
Yes. The cooling fan under a built-in induction hob can be audible during and after cooking. A loud grinding or rattling noise from the fan means the fan motor is wearing out.
Bosch induction hob E6 after fitting a new worktop — connected to the installation?
Very likely. A new worktop with a tighter cut-out or different cabinet configuration may have reduced the ventilation gap below the minimum requirement. Check the gap and adjust the installation accordingly.
