Possible Causes
Weak mains supply, loose terminal block connections, failing low-voltage power supply on control board, overloaded circuit
How to Fix / Troubleshooting
Safety first: Turn off power before tightening any electrical connections.
- Check circuit rating: Ensure the oven is on a dedicated circuit with the correct amperage as specified by De Dietrich.
- Inspect terminal block: Access the rear connection box and check that all live, neutral, and earth screws are tight and free of burning.
- Observe behavior: If flicker is minor and stable, it may be normal. Severe dimming suggests supply or board issues.
- Control board: If mains connections are sound, the low-voltage supply on the control board may be failing and require replacement.
