How to Fix / Troubleshooting

Safety first: Disconnect power before removing the control panel.

Steps to check:

  • Power cycle: Turn off the refrigerator at the breaker for 10 minutes, then restore power to reset the control software.
  • Check buttons: Press each control panel button individually to ensure none are stuck or unresponsive. Clean around the buttons with a soft, slightly damp cloth (no harsh chemicals).
  • Factory reset: If the user manual provides a factory reset procedure, follow it to clear custom modes and restore defaults.

Note: If E13 persists after reset and button checks, the main control board or UI board may require replacement and programming by an authorized Thermador technician.
