How to Fix / Troubleshooting
Safety: Do not attempt repairs on live circuits. Unplug the unit before inspecting the cord or internal components.
- Check outlet: Plug a lamp or other device into the same outlet to verify power. Reset any tripped breakers or GFCI outlets.
- Inspect power cord: Examine the cord for cuts, burns, or kinks. If damaged, replace the cord with the correct Blomberg part.
- Test at terminal block: With the rear panel removed and power disconnected, locate the power terminal block or connector on the main PCB. Verify that connections are tight and not burnt.
- Main PCB: If power is present at the board input but there is no display or response, the main control board's power supply may have failed. Replace the main PCB.
