Answer to continue safely
Is it safe to keep using?
No. The washer cannot operate without a functioning door lock. The lock is a critical safety interlock that prevents the door from opening during water fill and high-speed spin cycles. The lock assembly must be replaced before the washer can be used.
Can I reset the code?
No. E42 indicates a hardware failure in the lock assembly. Resetting the washer will not restore function because the lock solenoid or its wiring has physically failed. The lock assembly must be repaired or replaced.
When to stop immediately?
Stop if you notice: The lock connector shows burned or melted pins indicating an electrical fault, E42 appears consistently on every attempt after reseating the connector.
Symptoms You May Notice
E42 appears immediately when Start is pressed
The error displays within seconds of pressing Start because the control board receives no response at all from the door lock assembly — there is no delay or lock attempt sound.
No sound from the door lock area when starting a cycle
Unlike E40 or E41 where the lock may buzz briefly, E42 produces silence from the lock area because the solenoid does not activate at all.
Door lock indicator never illuminates
On models with a lock status indicator on the control panel, the indicator remains off after pressing Start, confirming no lock engagement is occurring.
Error persists through power cycles and reset attempts
Unlike intermittent E40 issues, E42 appears consistently on every start attempt because the lock hardware has completely failed rather than having a marginal connection.
Possible Causes
Burned-out door lock solenoid
The electromagnetic coil inside the door lock assembly has failed open-circuit due to overheating or age, making it impossible for the lock to engage when powered by the control board.
Requires ProfessionalDisconnected or damaged wiring harness
The wiring connector between the door lock assembly and the main control board has come loose due to vibration, or a wire has broken or corroded, severing the electrical connection entirely.
DIY PossibleFailed lock assembly circuit board
On Electrolux models with an integrated PCB in the door lock assembly, the circuit board has failed due to moisture intrusion or a power surge, preventing the lock from receiving or responding to signals.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the door lock wiring connector
Unplug the washer from power. Open the door and carefully peel back the top of the rubber boot seal to access the door lock mounting area. Locate the wiring connector going to the lock assembly. Disconnect it and inspect the pins for corrosion, burn marks, or damage. Reconnect it firmly.
Take a photo of the connector before disconnecting so you can verify the correct orientation when reconnecting.

2
Inspect the lock connector pins
Look closely at both the lock-side and harness-side connector pins. Corroded or darkened pins indicate moisture damage. Bent pins may not make proper contact. If pins are corroded, clean them gently with fine sandpaper or an electrical contact cleaner spray.
If one or more pins show burn marks or melting, the lock or the harness (or both) need replacement — cleaning alone will not restore a damaged connection.

3
Power cycle and test
After reseating or cleaning the connector, tuck the boot seal back into place, plug in the washer, close the door, and press Start. Listen carefully for any sound from the lock area within 5 seconds. If the lock engages and the cycle begins, run a full cycle to confirm the fix.
If E42 persists after reseating the connector, the lock assembly itself needs replacement — there are no further DIY steps for this error.
When to Call a Professional
Contact a qualified technician if:
- The door lock solenoid reads open-circuit on a multimeter, confirming a burned-out coil
- The harness wires at the lock connector show heat damage or insulation melting
- The control board lock relay outputs correct voltage but the lock does not respond, isolating the fault to the lock assembly
