Step by step
-
1 Confirm the lock is actually the problem
Check the outlet and breaker first, and note the symptom. Flashing lid lock light with clicks is the classic failed lock signature on most top loaders.
-
2 Open the top panel
On most top loaders the whole top hinges up. Slide a putty knife under the front corners of the lid panel to release the spring clips, or remove the rear screws, then tilt the top back.
-
3 Unplug the old lock
The lock sits under the top panel at the lid opening’s front edge, one wiring plug and two or three screws.
-
4 Fit the new lock
Screw the new assembly into the same spot, connect the plug until it clicks, and route the harness exactly where the old one sat.
-
5 Reassemble and test
Snap the top down, plug in, and start a cycle. You should hear the lock engage and see the lid light go solid.

If a new lock still flashes errors, the control board or its harness is suspect, that diagnosis is faster (and cheaper) with a tech’s meter than with parts roulette. If you'd rather skip it entirely, find a washer repair pro near you
