Step by step
-
1 Open the inner door panel
With the door open, remove the ring of screws around the inner panel edge (often Torx). Close the latch, then separate the outer panel carefully, the control panel wiring stays attached, so lean it forward gently.
-
2 Find the latch at the top center
The latch assembly with its microswitches sits at the door’s top edge. Photograph the wiring orientation.
-
3 Swap the assembly
Unclip or unscrew the old latch, transfer the wires to the same terminals on the new one, and seat it in the same position.
-
4 Reassemble and align
Panel screws back in, then close the door. It should latch with a positive click, no slamming. If it misses the strike, loosen the strike plate and adjust.
-
5 Test a full cycle
The true test is a wash that runs start to finish without the door fault reappearing, bump the door mid cycle to be sure.
