Possible Causes
Blown internal fuse, Faulty main switch, Loose power connector, Defective control board
How to Fix / Troubleshooting
Safety: Isolate the boiler from the mains before opening the electrical compartment.
- 1. Check external power: Verify that the dedicated boiler circuit breaker is on and that there is mains voltage at the boiler terminals.
- 2. Inspect main switch: Ensure the boiler’s on/off switch operates correctly and is not loose or burnt.
- 3. Internal fuse: Locate and check the internal fuse(s) on the Brötje control board. Replace only with the same type and rating. If it blows again, a deeper fault exists.
- 4. Control board: If power and fuse are OK but the display remains dead, the control board is likely defective and must be replaced.
