How to Fix / Troubleshooting

Safety first: Before opening any covers, switch off the breaker and verify absence of voltage.

User checks:

  • Ensure the cooktop's plug (if fitted) is fully inserted.

Technical steps:

  • Inspect the terminal block for loose or burnt connections; tighten and replace damaged parts.
  • Check internal fuses on the mains filter or control board and replace only with identical rated fuses.
  • If fuses blow again immediately, locate and repair the underlying short before further use.
