Problem: Sanitizer pump runs continuously.
1. Shorted prime switch. If there is not 120 volts between the GREY and WHITE/RED wires to the prime switch, replace it.
2. Shorted sanitizer microswitch on the cam timer. If there is not 120 volts between the ORANGE and GREY wires on the san-
itizer microswitch when the switch is out of the “home” position, replace the switch.
Problem: Sanitizer pump does not run during the cycle, but does run when primed.
1. Loose or broken wire. Verify that all wires are whole and that their connections are tight.
2. Faulty sanitizer microswitch on the cam timer. With the sanitizer cam in the “home” position, measure the voltage between
the ORANGE and GREY wires on the microswitch. If it reads 120 volts, replace the microswitch.
Problem: Prime switch does not activate the sanitizer pump.
1. Faulty prime switch. With the prime switch in the prime position, check for voltage between the GREY and the WHITE/RED
wires to the prime switch. If it reads 120 volts, replace the switch.
2. Faulty delime switch. With the delime switch in the DELIME position, check for voltage between the WHITE/BLACK and
WHITE/RED wires to the delime switch. If it reads 120 volts, replace the switch.
Problem: Sanitizer pump doesn’t run during the cycle or through the prime switch.
1. Loose sanitizer pump motor wire. Verify and tighten connections to the motor.
2. Faulty sanitizer pump motor. If you read 120 volts at the sanitizer motor terminals during the sanitizer feed cycle, replace
motor.
Problem: Detergent not feeding, rinse aid feeds correctly.
1. Misadjusted cam. Adjust the detergent cam on the timer.
2. Faulty detergent microswitch on the cam timer. With the detergent cam in the “home” position, measure voltage between
ORANGE and GREY/WHITE wires. If it reads 120 volts, replace the microswitch.
Problem: Rinse aid not feeding, detergent feeds correctly.
1. Misadjusted cam. Adjust the rinse aid cam on the timer.
2. Faulty rinse aid microswitch on the cam timer. With the rinse aid cam in the “home” position, measure the voltage between
the ORANGE and ORANGE/YELLOW wires. If it reads 120 volts, replace the microswitch.
