AEG E9 on hob: possible electronic module fault
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
Your AEG hob shows E9 because it detects a potential issue with the electronic circuit board. Disconnect it from the power for at least 30 seconds and reconnect it; if E9 remains, stop using it and book an authorised technician.
Safety first
Stop and check this first
- AEG advises against using the hob until the issue is resolved: disconnect it and do not reconnect it until you are sure it is safe. Do not open the hob: the electronics run on mains voltage.

What it means
AEG states that E9 on its hobs indicates a fault in the electronic module, a potential issue with the circuit board. It suggests a reset first, disconnecting the appliance for at least 30 seconds, and warns that there may be a bigger problem needing a competent, qualified person. The code alone does not prove the electronics must be replaced: a reset may solve it, and only a technician can confirm a fault.
