What this error means
Door lock fault — the machine cannot detect or secure the door
The E01 error means the door lock mechanism has failed to engage or has lost contact with the control board. This prevents the cycle from starting or continuing. It is most commonly caused by the door not being pushed fully shut, debris trapped in the door seal, a worn latch hook, or a faulty door interlock switch.
Step-by-step
Symptoms to look for
- Door will not lock at the start of a programme
- Machine starts then stops immediately with E01 on the display
- Cycle pauses mid-wash with a door fault error
- Door appears fully closed but the machine will not begin
Diagnostic steps
Press the door firmly with both hands on the outer plastic frame — never push on the glass. You should hear and feel a solid click as the latch snaps into the catch plate. The door face should sit completely flush with the machine body.
Run your fingers slowly around the entire rubber door seal, pressing gently into the folds. Feel for trapped clothing, coins, hair grips, or any debris. Remove anything found. Pay particular attention to the lower section where items most commonly collect.
Open the door and inspect the plastic latch hook on the door edge. It must be intact with no cracks, chips, or visible bending. Examine the catch plate slot on the machine body. Both parts must be undamaged and correctly aligned.
With the machine unplugged, look into the catch plate opening on the machine body. The interlock switch is the small electrical mechanism inside. Check it is not obstructed, discoloured, or showing signs of burning or melting.
Open the door fully and examine the top and bottom hinge points. Apply gentle upward pressure on the door edge — if it lifts noticeably the hinge is worn. A sagging door misaligns with the catch plate and causes intermittent E01 faults.
Unplug the machine and hold the power button for 5 seconds to discharge the control board. Leave unplugged for 60 seconds. Plug back in and try a short programme.
When to call an engineer
- Door interlock switch fails a continuity test with a multimeter
- Door latch hook is visibly cracked, bent, or broken
- Door hangs lower on one side — hinge is worn or damaged
- Wiring to the door interlock is burnt or the connector has melted
