Possible Causes

Failed main power relay on PCB, burnt relay contacts, open-circuit wiring from relay to elements, blown internal fuse on control board

How to Fix / Troubleshooting

Safety first: Disconnect power. Internal fuses and relays are on live circuits; only work on them when fully de-energised.

Board and wiring checks:

  • Access the main control board and visually inspect for burnt relays, darkened PCB areas, or blown fuses.
  • Test continuity across any internal fuses and replace only with the same type and rating.
  • Check that live output from the main relay reaches the element circuits (requires schematic and careful testing).
  • If the main relay is visibly damaged or does not click when a heating function is selected (with power on, by a qualified person), the board likely needs replacement.
