Safety: Unplug and allow the unit to cool completely before inspection.

Clean grill area: Remove the grill rack and clean grease and food splatter from the ceiling and around the grill element using a non-abrasive cleaner.
Ventilation: Ensure top and rear vents are clear to allow heat to escape.
Test in microwave-only mode: If microwave-only works but grill/combination triggers E11, the grill circuit or sensor is likely faulty.
