How to Fix / Troubleshooting
Safety first: Unplug the appliance before accessing the display or control board.
Steps to correct display issues:
- 1. Check for condensation: If the display is fogged or wet, allow it to dry completely with the unit unplugged.
- 2. Access display module: Remove the front control panel to expose the display PCB and connectors.
- 3. Reseat connectors: Disconnect and reconnect the display cable(s) to ensure a solid connection.
- 4. Inspect for damage: Look for corrosion, burnt components, or cracked solder joints on the display board.
- 5. Replace display PCB: If flickering or random characters persist, install a new Brandt display/user interface board.
- 6. Main board check: If a new display is still dim or unstable, the low-voltage supply on the main control board may be faulty and require replacement.
