Error codes
| Code | What it means |
|---|---|
| tE1 / tE2 | Thermistor fault |
| dE | Door circuit fault |
| D80 / D90 / D95 | Vent blockage percentage |

Tech notes
The D-series vent codes are diagnostic gold and no other brand states blockage this plainly. Treat a D90 or D95 as an urgent airflow job rather than a nuisance message.
