Possible Causes

Loose connection between user interface board and main PCB, Faulty control panel (UI) board, Damaged ribbon cable, Main PCB failure

How to Fix / Troubleshooting

Safety first: Unplug the washer before removing the top or control panel.

Reset the control:

  • Unplug the washer for 5 minutes to discharge capacitors.
  • Plug back in and try to start a simple cycle. If D06 clears temporarily, suspect an intermittent connection.

Inspect control connections:

  • Remove the top cover to access the main PCB and the control panel harness.
  • Remove the control panel (usually held by screws and clips at the front).
  • Check the ribbon cable or harness between the UI and main PCB for damage, corrosion, or loose plugs. Reseat all connectors firmly.

Visual inspection:

  • Look for burn marks, cracked solder joints, or moisture damage on both boards.

If D06 persists after reseating and there is visible damage, replace the affected board (UI or main PCB). Board-level repair should be done by an experienced electronics technician.
