Possible Causes

Incorrect supply wiring (single phase on multi‑phase hob), Overloaded internal supply, Faulty load management circuit on control board, Shorted heating element

How to Fix / Troubleshooting

Safety first: Isolate the hob and verify wiring only if you are qualified; otherwise, call an electrician.

Technician checks:

  • Confirm the hob is wired according to the Caple wiring diagram (bridges correctly fitted for single‑phase, or separate phases for two‑phase models).
  • Measure current draw on each phase while operating multiple zones to ensure it is within rated limits.
  • Inspect each heating element (induction or radiant) for signs of shorting or damage.
  • Check the load management circuitry on the main control PCB for burnt components.

Remedy: Correct wiring errors, replace any shorted elements, and if necessary replace the main control PCB if its current sensing is faulty.
