What the appliance detected
Detected condition
The dryer is reading the door as open or not fully closed.
What may contribute
Possible causes
- The door may not be fully closed.
- Clothing, lint, or another visible obstruction may be preventing normal closure.
- The visible latch or strike may not be engaging normally.
- If the door closes normally but E42 returns, internal latch, switch, wiring, or control diagnosis may be needed.
Start conservatively
Safe preliminary checks
Work in order and stop whenever a step is not supported by the documentation for your model.
Record E42 and stop the dryer
- Photograph the display and note the complete model number.
- Wait for the drum to stop before checking the door opening.
Clear visible obstructions
- Remove clothing or debris caught between the door and opening.
- Wipe loose lint from the visible latch area without inserting tools into the latch mechanism.
Close the door normally
- Close the door firmly without slamming it and confirm it stays shut.
- Inspect only the visible latch and strike for obvious damage; do not remove the switch or front panel.
Actions not recommended
- Do not bypass or tape down a door switch.
- Do not force a door that will not close normally.
- Do not remove panels or test live wiring to chase E42.
When to stop and request service
- E42 returns with the door fully closed and no visible obstruction.
- The latch or strike is visibly damaged or the door will not stay closed.
- The next step would require internal switch, wiring, or control diagnosis.
