Answer to continue safely
Is it safe to keep using?
No. A front-loader with a faulty door lock must not be operated. The door lock is a primary safety device — an unlocked door during a spin cycle poses a serious hazard. Do not attempt to bypass or force the lock.
Can I reset the code?
Yes. Power-cycling clears DL from the display. If the door lock actuator is functioning and the door is fully closed, the code will not return. Persistent DL after power-cycle confirms a mechanical or electrical fault in the door lock system.
When to stop immediately?
Stop if you notice: Never attempt to bypass or wedge the door lock open during a cycle, If you hear the lock attempting to engage repeatedly and failing, stop attempting cycles to avoid burning out the solenoid.
Symptoms You May Notice
DL displayed at cycle start
The machine raises the DL fault when it attempts to lock the door before starting a cycle and does not receive confirmation that the lock has engaged.
Door will not lock — machine will not start
Pressing Start prompts the machine to attempt door locking, but the cycle never begins and DL is shown.
Cycle aborts mid-wash with door lock fault
On machines where the lock actuator overheats or fails under load, DL can appear mid-cycle, halting the cycle with a full drum.
Possible Causes
Faulty door lock actuator
The electronic door lock solenoid or actuator assembly has failed and cannot physically engage the lock bolt.
DIY PossibleWorn door latch or strike plate
The door latch hook or the strike plate it engages on the machine body has worn or broken, preventing the lock from securing the door.
DIY PossibleDoor not fully closed
A garment caught in the door seal is preventing the door from reaching the fully-closed position required for lock engagement.
DIY PossibleDoor lock wiring fault
The wiring between the door lock assembly and the main PCB has broken or become intermittent.
DIY PossibleFailed main PCB lock output
The PCB circuit that energises the door lock solenoid has failed.
Requires ProfessionalSafe Checks You Can Do
-
1
Check for door obstruction
Open the door fully and confirm no clothing or fabric is caught in the door seal or between the door glass and the boot seal. Close the door firmly and retry.
The boot seal on front-loaders can fold inward and catch fabric — run your finger around the full circumference of the seal before closing.
-
2
Inspect door latch hook & strike
Visually inspect the latch hook on the door and the strike plate on the machine body. Look for cracks, wear, or misalignment. Try closing the door with firm pressure and listen for the lock click.
A worn latch hook is a common failure point after 5–8 years of use on WH series front-loaders.
-
3
Test door lock actuator
With the machine unplugged, access the door lock assembly (inside the front panel behind the door seal). Measure resistance across the lock solenoid coil. A healthy solenoid typically reads 200–400 ohms; open circuit confirms failure.
The door lock assembly on most WH series models is a plug-in unit that can be replaced without soldering.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Wiring from the door lock to the main PCB runs through the door hinge area and may require door disassembly to access
- Main PCB lock output failure requires board replacement or repair by a qualified technician
