How to Fix / Troubleshooting

Safety first: Disconnect power before removing the door panel or control panel.

  • Confirm door closure: Ensure nothing is obstructing the door and that racks are fully pushed in.
  • Check for error indicators: Some Bosch models show a small key or lock symbol if child lock is active. Disable child lock per the user manual.
  • Test door latch: Listen for a click when closing the door. If the latch feels loose or does not click, inspect and replace the latch assembly.
  • Inspect control panel: Remove the inner door panel to access the UI board. Check for moisture, corrosion, or loose ribbon cables. Dry and reseat connectors.
  • Replace faulty UI: If buttons do not respond and wiring is intact, replace the Bosch control panel/user interface board.
