Microwave displays E10 and will not start; often after a door slam or impact.

Safety: Unplug the microwave before inspecting the door mechanism.

Door inspection:

• Open the door and inspect the plastic latch hooks on the door edge. Look for cracks, missing pieces, or deformation.
• Check that the door closes smoothly and aligns evenly with the cabinet. There should be no significant gaps.
• Inspect the strike area on the cabinet where the hooks engage. Look for bent metal or broken plastic guides.

Adjustment and cleaning:

• Remove any debris or food residue around the latch area.
• If the door appears slightly misaligned, gently lift or press on the handle while closing to see if the error clears temporarily. This indicates hinge or latch wear.

Technician repair:

• Replace broken door latch hooks or the complete door assembly as required.
• Adjust or replace the internal latch bracket.
• Verify correct operation of all door interlock switches after mechanical repairs.

Because the door system is a primary safety feature, structural repairs should be carried out by a qualified technician using OEM SMEG parts.
