Wi-Fi Board
Main Board
The main board powers the User Interface (UI)
and Inverter boards. The main board receives
commands from the User Interface board and
controls washer operation, communicating with
the UI and inverter through low voltage pulses.
The main board is enclosed in a protective
housing and cover located inside the cabinet, at
the top right side of the washer cabinet.
Main Board Diagnosing
Check for 120 VAC at the outlet. If voltage is
there, check for 120 VAC between the
black
and
white
wire at the J101 connector on the main
board. If no voltage is found, check the wire
harness and connector integrity. If voltage is
found at the main board, but no heartbeat LED
flashing on the main board, replace the board.
