Pins Voltages
1 and 2 5 VDC
1 and 3 12 VDC
1 and 4 20 VDC
After 5 minutes, if there is no additional input, •
the washer shuts off and the power LED shuts
off. There is no voltage on pins 1 and 3 and 1
and 4 at this time.
If the washer operates through a cycle, the •
inverter voltages at CON2 will be present until
the lid is opened.
If the Power LED is lit and if one of the three •
voltages (5 VDC, 12 VDC, or 20 VDC) at CON2 is
not present, the inverter is bad.
When the washer is turned on by pressing a •
membrane pad, the Power LED on the inverter
comes on.
When the Power LED is on, the 12-VDC power •
supply on the inverter board is energized and
the below listed voltages are on CON2:

Brake Resistor
The brake resistor absorbs energy from the •
reversing of the motor during the brake cycle.
The brake resistor only operates when the •
washer loses power or the lid is lifted during a
cycle.
Under normal operation, the tub coasts to a •
stop at the end of a cycle.
The approximate resistance value of the brake •
resistor is 70 Ω.
If the resistor is shorted, the motor will not start. •
If the resistor opens while the motor is spinning, •
the inverter board can be damaged.
Look for a burnt IC labeled IC300 on the inverter •
board. Both the resistor and inverter board
should be replaced if the IC300 is damaged. (See
Testing the Inverter photo.)
To remove the brake resistor:
Remove the 2 Phillips-head screws that hold the 1.
brake resistor in place.
Disconnect the 2 wiring harnesses from the 2.
brake resistor. Remove the brake resistor from
the mounting pin.
