Check Input/Output PCB for illuminated red output light for inter-
mediate spin (Speed 1) #15 and #14
FOR REVERSE. If no red output light illuminated,
check single red light on CPU board. Single red
light should be illuminated. If light is flashing or not
on, remove power from washer for 2 minutes to
reset board. Reapply power to washer and check
red CPU light. If on solid, CPU okay. If still flashing
or not on, replace CPU board. If CPU tests okay,
change Ribbon Cables between CPU and Input/
Output PCB. (Check with factory for latest testing
procedures for I/O PCB). If red speed 1#
output light # 15 on the Input/Output PCB is
illuminated, check to insure that 0VDC is going
from the Input/Output PCB to the variable
frequency drive. If no voltage, replace I/O PCB.

Drive and Motor
Check small green, blue, orange, black, white, red wires (shielded
cable) from the VFD to insure a good connection at each termina-
tion point at drive or at relays and including all molex connectors.
1. Disconnect power to washer for 2 minutes to reset motor drive.
2. Check incoming power to washer for correct voltage. Line volt-
age out of the specified operating range will cause the drive to
fault, lighting the red fault light.
3. Check motor. Disconnect from power. Disconnect the three
wires that operate the motor from terminals T-1, T-2, T-3 in the
drive. Reconnect power to the washer

PCB
Check Input/Output PCB for illuminated red motor output lights.
If no red output lights illuminated, check single red light on CPU
board. Single red light should be illuminated. If light is flashing or
not on, remove power from washer for 2 minutes to reset board.
Reapply power to washer and check red CPU light. If on solid,
CPU okay. If still flashing or not on, replace CPU board. If CPU
tests okay, change Ribbon Cables between CPU and Input/Output
PCB. (Check with factory for latest testing procedures for I/O PCB)
If red motor output lights on Input/Output PCB are illuminated,
check to insure that 0VDC is going from the input/output board to
the variable frequency drive. If no voltage, replace I/O PCB.
Run Relay Check to see if 12VDC to relay coil. If not check I/O PCB.for
12VDC output. Check if 0VDC through contacts (white wire) to I/O
PCB.
