Electrolux Dryer E42 Error Code — What It Means
E42 on an Electrolux dryer means the control is not recognizing the door lock or door closed signal. The machine is not seeing a valid closed-door input from the door switch or latch circuit. This is a door-lock or door-switch fault, not a heating or motor issue. Electrolux support describes the code as the door lock not being recognized, and repair references for Electrolux IQ-Touch dryers label it as a door open or door malfunction condition.
Common Causes
- Door not fully latched The door is not completely shut or laundry is caught between the door and seal, preventing the latch from engaging.
- Faulty door switch or door lock assembly The door switch or door interlock assembly has failed and is no longer sending a closed signal to the control board.
- Latch or striker misalignment The mechanical latch or striker is worn, broken, or misaligned and cannot engage properly when the door closes.
- Loose or damaged wiring The wiring harness or connectors at the door assembly or switch are loose, broken, or intermittent.
- Overloading the drum Too much laundry in the drum can prevent the door from closing and latching fully.
- Child safety lock engaged If your model has a mechanical child-safety lock, it may be accidentally engaged and blocking the door from closing.
Step-by-Step Fix
- Unplug the dryer or turn off the breaker, then open and close the door firmly to verify it latches completely and nothing is caught in the seal.
- Listen and feel for the latch click when you close the door to confirm the striker engages properly.
- Check that the child-safety lock (if equipped) is not engaged and that the door closes without resistance.
- Inspect the door latch, striker, and door lock assembly for visible damage, wear, or misalignment.
- Remove the door assembly access panel and check all wiring and connectors at the door switch for loose, broken, or corroded terminals.
- Test the door switch with a multimeter to verify it closes (shows continuity) when the door is latched and opens when the door is open.
- If the door switch and wiring test good but the fault remains, replace the door lock assembly or consult the main control board as a last resort.
Parts Often Needed
| Part | Notes |
|---|---|
| Door switch / door interlock switch | Amazon | Replace if continuity test shows open or intermittent reading when door is closed. |
| Door lock assembly | Amazon | Use if the switch tests good but the door lock mechanism itself is faulty or damaged. |
| Door latch and striker | Amazon | Order if the mechanical latch path is broken, worn, or visibly misaligned. |
| Main control board | Amazon | Only needed after door-side parts and wiring are confirmed good and fault persists. |
When to Call a Pro
Call a technician if you are not comfortable working with multimeters or disassembling the door panel to access the switch and wiring. If you have tested the door switch, inspected the wiring, and confirmed the latch is working but the E42 code still appears, the issue may be in the door lock assembly or main control board. A qualified appliance repair tech can perform full circuit diagnostics and replace board-level components safely.
