DISASSEMBLY/REPAIR
Often, you can diagnose a failed part by removing its connector on the main
board and connecting the tester to the leads in the connector. (See page 45.)
WM2277 WASHER

(Main Board)

1. Disconnect the POWER
connector and the Water Level
Sensor Switch.
2. Remove the protective cover.
Press the plastic tabs out of the
way to remove the cover. The
main board is potted, so no
repairs are possible.
Replacement is the only option.
3. Disconnect the connectors on
the main board. They are all
different, keyed, and color-
coded to prevent incorrect
connection.
4. Pull the wires out of the way.
5. Remove one screw on the back
of the washer to release the
main board housing.
6. Remove the main board by
sliding it to the right and lifting
it up.
Replacement is accomplished
by pressing it toward the back
of the washer and sliding it
toward the left.
