How to Fix / Troubleshooting

Safety first: Unplug before accessing internal sensors.

  • Step 1 – Clean cavity and sensor area: Thoroughly clean the interior, especially near the steam outlet and sensor grille.
  • Step 2 – Use correct cookware: Follow AEG instructions for sensor programs (usually microwave-safe, non-metallic containers, uncovered or loosely covered).
  • Step 3 – Vent check: Ensure vents are not blocked so steam can reach the sensor properly.
  • Step 4 – Sensor replacement: If performance remains poor, the humidity sensor may be out of calibration and should be replaced.
