This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect mains power before removing the control panel or accessing the electronics.
Access the control panel:
- On upright Blomberg freezers, remove the screws securing the top or front control fascia.
- Carefully pull the panel forward to expose the display PCB and wiring harness.
Inspect connections:
- Locate the multi-pin connector(s) between the display board and the harness.
- Unplug and re-seat each connector several times to clean contacts. Check for bent pins or corrosion.
Check harness continuity:
- Trace the harness from the display to the main control board (usually at the rear or base).
- With the unit unplugged, use a multimeter to verify continuity on each communication line if you have access to the pinout.
Visual inspection of PCBs:
- Look for burned components, cracked solder joints, or moisture damage on both the display PCB and main PCB.
Corrective actions:
- Secure wiring: Ensure the harness is not pinched by cabinet panels and is firmly clipped in place.
- Replace display PCB: If the display is unresponsive, segments are missing, or there is visible damage, replace the user interface/display board with a Blomberg-compatible part.
- If the display board appears good and wiring is intact but E6 persists, the main control board may have a communication fault and should be replaced.
Test: Reassemble the control panel, restore power, and verify that all buttons respond and that E6 does not reappear.
