Vacuum motor contactor coil open
1. Check for an open circuit in the
K1
coil and wiring
(wire colors VIO and BLU).

K1
Vacuum motor contactor coil
short to ground
1. Disconnect the
K1
coil wiring (wire colors VIO and
BLU) and check to see if the code disappears.
−
If the code disappears, replace the motor contactor.
−
If the code does reappear, test the wiring for a short
back to the battery ground. Repair or replace the
defective wire.
2. If the above test doesn’t remove the code, substitute
a new A2 control board assembly.
32
Squeegee actuator open
1. Check for disconnected squeegee actuator motor
wiring or plug connection.
2. Check for an open circuit in actuator motor wiring
(WHT/GRN and BLU/BRN) or for a defective motor
M3
.
3. Check for 36 Volts at the actuator motor. If 0 Volts,
check the A2 control board assembly.

Solution solenoid open
1. Check for an open circuit in the
L1
coil and wiring
(wire colors VIO and YEL/GRN).
