Possible Causes
How to Fix / Troubleshooting
Safety first: Switch off the cooktop before inspecting any wiring. Work on live circuits must be done by a qualified electrician.
User checks:
- Turn off other heavy-load appliances (ovens, heaters) on the same circuit and test the cooktop again.
- If lights dim when the cooktop is used, this indicates a supply issue that needs an electrician.
Electrician/technician checks:
- Measure the voltage at the cooktop terminal block while the cooktop is operating.
- Inspect the supply cable size and length to ensure it meets Siemens installation requirements.
- Tighten all terminal screws and check for heat discoloration.
- If supply is stable and within spec, but E4 persists, test and replace the power module as needed.
Do not attempt to modify house wiring yourself; improper wiring can cause fire or electric shock.
