Possible Causes
Undersized supply cable, Loose connection at terminal block, Low mains voltage, Failing power module
How to Fix / Troubleshooting
Safety first: Turn off power at the mains before any inspection of the terminal block. Only a qualified electrician should remove covers.
- Check other appliances: If lights dim or other appliances struggle, there may be a general low-voltage issue. Contact your energy supplier or electrician.
- Verify cable size (electrician): Ensure the hob is wired with the correct cross-section cable as specified by Montpellier (often 6 mm² for higher power models).
- Tighten connections (electrician): With power isolated, check all screws in the hob terminal block and cooker switch are tight and free of heat damage.
- Test again: Restore power and test each zone. If E4 persists on a single zone, the power module for that zone may be failing and should be replaced.
