Both incoming and exiting voltage are monitored through the machine control board and the
surrounding circuitry. The following table lists the voltages for the various terminals on the
microprocessor board. If proper voltage is not present, check switches and wiring for any
loose connections or open circuits by disconnecting the power supply and performing conti-
nuity checks of individual circuits.

To check voltages from the board, turn timer dial to a wash cycle and press the start/off button.
This will activate the L1 relay board and apply power on the machine control.

Machine Control
The machine control microprocessor board is located in the control console, mounted to the
rear panel. The board receives input from the timer, door latch and lock switches, and unbal-
ance and selector switches on the console. It also communicates with the motor control board
to facilitate the various cycles and drive the motor for optimum performance. Torque and
speed of the motor are monitored through the motor control board.
