Code E1
high severity
Indesit models: Indesit ovens are budget-tier freestanding models. Standard temperature probe at the rear cavity wall. Most Indesit ovens use catalytic self-cleaning panels rather than pyrolytic — do not use spray oven cleaners on the catalytic panels.
Common causes
- Temperature probe reading slightly off its calibrated value
- Probe has aged and drifted from its original specification
Step-by-step fix
- Use an independent oven thermometer to measure actual cavity temperature at 350°F.
- If actual temperature deviates by more than 25°F, adjust the calibration offset in the oven's settings menu.
- If deviation exceeds 50°F, the probe likely needs replacement.
Tools you may need
Independent oven thermometerMultimeter (optional)
Prevention
- Check calibration annually with an oven thermometer.
- Avoid extremely high self-clean temperatures unless necessary.
When to stop DIY
Replace the temperature probe if calibration offset cannot compensate for the drift.
