Possible Causes
Loose mains terminal block, Undersized extension cord, Failing internal power supply capacitor, Shared circuit overloaded
How to Fix / Troubleshooting
Safety first: Switch off power before tightening any electrical connections.
- Avoid extension cords: Plug the oven directly into a suitable wall outlet or dedicated circuit as recommended by Severin.
- Check terminal block: Tighten all screws on the mains terminal block and inspect for discoloration.
- Inspect internal PSU: On the control PCB, look for swollen electrolytic capacitors in the low-voltage supply. Replace the board if components are failing.
- Electrical load: Ensure the oven is not sharing a circuit with other high-power appliances that could cause voltage sag.
- Test: After corrections, observe the display while heating. It should remain stable.
