How to Fix Error E030
- 1
Power cycle the appliance
Unplug for 5 minutes. Door lock mechanisms often reset after a power cycle. Plug back in and try opening/closing the door.
- 2
Inspect the door latch
Look at the latch mechanism where the door meets the frame. Check for food debris, mineral buildup, or visible damage preventing it from clicking into place.
- 3
Clean the latch area
Wipe down the latch, striker plate, and surrounding area with a damp cloth. Dry thoroughly. Accumulated grime is a common cause of latch errors.
- 4
Check door alignment
Close the door slowly and watch if it lines up with the frame evenly. If the door has sagged, the hinges may need adjustment or replacement.
- 5
Test the door switch
The door switch is usually a small button-style switch near the top or side of the door opening. Press it by hand — you should hear/feel a click. Test for continuity with a multimeter.

Replace the door latch or switch
If the latch is broken or the switch doesn't click, order a replacement. Most are held by 2 screws and a wire connector.
