What this error means
Door lock fault — the machine cannot detect or secure the door
The F06 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 fully closed, a worn latch, a faulty door interlock switch, or debris caught in the door seal.
Step-by-step
Symptoms to look for
- Door will not lock at the start of a programme
- Machine starts then stops immediately with F06 on the display
- Cycle pauses mid-wash with a door fault error
- Door appears fully closed but the machine will not begin
Diagnostic steps
Stand directly in front of the machine and 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 you find. Pay particular attention to the lower section where items collect most.
Open the door and inspect the plastic latch hook on the door edge. It must be intact with no cracks or chips. Then examine the catch plate recess on the machine body — the slot the hook enters. Both parts must be undamaged and correctly aligned.
With the machine unplugged, look closely into the catch plate opening on the machine body. Inside you will see a small electrical switch mechanism. Check it is not obstructed, discoloured, or showing any signs of burning or melting.
Open the door fully and examine the hinge points at the top and bottom. 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 F06 faults that come and go.
Unplug the machine and press and hold the power button for 5 seconds to discharge residual power. 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 than normal — hinge is worn or damaged
- Wiring to the door interlock is burnt, frayed, or the connector has melted
