If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety warning: The induction power stage carries high voltage and high current. Only qualified personnel should open the hob.
User actions:
- Note which zone shows E7 and avoid using it.
- Reset the hob at the breaker; if E7 reappears immediately on the same zone, internal hardware is likely damaged.
Technician actions:
- Remove hob, inspect the induction coil for discoloration, cracks, or burnt smell.
- Measure coil resistance; an open or shorted reading indicates a failed coil.
- Inspect the power module for burnt components, especially IGBTs and associated drivers.
- Replace the defective coil and/or power module as a matched set if required by AEG.
Do not attempt to bypass a failed zone; this can create fire and shock hazards.
