How to Fix / Troubleshooting
Safety first: Disconnect from the mains before removing the hob from the worktop. Heating elements can remain hot for a long time.
- Visual inspection: Remove the bottom cover and inspect the radiant elements for visible breaks or burn marks.
- Check wiring: Ensure all spade connectors to the affected element and relays are tight and not discolored.
- Continuity test (advanced): Use a multimeter to check the continuity of the element. An open reading indicates a failed element.
When to call a technician: Replacing elements or power boards involves mains wiring and should be done by a qualified technician if you are not experienced.
