How to Fix / Troubleshooting
Safety: Disconnect from mains before working inside the cabinet.
E13 on dual-zone De Dietrich wine coolers usually indicates a problem with the lower compartment temperature sensor.
- Locate the lower zone sensor: It is typically mounted on the rear or side wall of the lower compartment, similar to the upper zone sensor.
- Inspect for damage: Bottles or shelves can sometimes impact the sensor; check for cracks or broken mounts.
- Resistance test: Unplug the sensor and measure resistance at room temperature. Compare with the upper zone sensor; large discrepancies suggest failure.
- Check harness routing: Ensure the cable is not pinched under shelves or at the cabinet base.
- Replace sensor: Fit a new lower zone NTC sensor if readings are out of range. Secure it firmly to ensure good thermal contact with the liner.
- Re-test: Restore power and confirm that the lower zone cools correctly and that E13 is cleared.
