AEG Oven E1 Error Code: Causes and Fixes

Editorially reviewedUpdated 2026-02-20

Quick answer: Temperature calibration drift

What you’ll notice

Oven consistently cooks hotter or cooler than the set temperature; calibration has drifted.

AEG Oven Code E1 medium severity
AEG models: AEG ovens include Pyrolytic self-cleaning (reaching 480°C/900°F). Do not attempt to override the electronic door lock during pyrolysis. SteamBake models have a front-left water reservoir — empty it before running a pyrolysis cycle to prevent steam-system fault codes.

Common causes

  • Temperature probe reading slightly off its calibrated value
  • Probe has aged and drifted from its original specification

Step-by-step fix

  1. Use an independent oven thermometer to measure actual cavity temperature at 350°F.
  2. If actual temperature deviates by more than 25°F, adjust the calibration offset in the oven's settings menu.
  3. If deviation exceeds 50°F, the probe likely needs replacement.

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.

FAQ

What does E1 mean on AEG oven?

E1 usually indicates: Temperature calibration drift.

Can I keep using the appliance with E1?

Use caution. Severity is medium. Replace the temperature probe if calibration offset cannot compensate for the drift.

How long does this fix usually take?

Typical first-pass troubleshooting takes 10 minutes (calibration adjustment).
