TROUBLESHOOTING
OBSERVATION
Dishmachine will not run,
no voltage at wash relay
terminals L1 and T1.
Machine will not run in "ON"
position unless cam timer
is moved off the "home"
position.
Machine will not run in "ON"
position but works in Delime
mode.
Machine will not run. Wash
pump motor will run if wash
relay is depressed manually
(nothing else works).
Machine will not run in "ON"
position or in Delime mode.
Machine cycles continuously.
Machine fills continuously
even with no power
applied to the machine.

POSSIBLE CAUSE
1. Service disconnect switch
off or faulty.
2. Branch circuit breaker
tripped/fuse blown.
3. Loose or broken connection
to dishmachine.
1. Door switch shorted out.
2. Faulty control relay.
3. Faulty "cycle reset"
microswitch in cam timer.
1. Faulty cycle reset cam
microswitch.
2. Faulty cam timer motor.
3. Faulty control relay.
4. Faulty NORMAL/DELIME
switch.
1. Open door switch.
2. Faulty control relay.
1. Door switch is defective.
2. Faulty OFF/ON/FILL switch.
3. Faulty NORMAL/DELIME
switch.
1. Cycle reset switch loose.
2. Faulty cycle reset switch.
1. Incorrect pressure.
2. Water inlet solenoid valve
allowing water into machine.
TROUBLESHOOTING
REMEDY
1. Turn disconnect on.
2. Reset or replace.
3. Tighten or replace connections.
1. With the door open, check for voltage between
ORANGE/WHITE door switch and neutral. If 120 V,
replace the door switch.
2. With the door open, check for voltage between connections #9
and #3 on control relay. If 120 V, replace control relay.
3. Replace microswitch.
1. With the switch in the Normal position, rotate the cams
manually off the home position. Check the voltage between the
ORANGE and BLACK/WHITE wires on the cycle reset switch.
If it is 120 V, then the switch is open and should be replaced.
2. If cam timer is not rotating, check the voltage to the motor. If
voltage is present when the door is closed, replace the motor.
3. Check the voltage across contacts #9 and #6. If 120 V when
the door is closed, replace the relay.
4. In the NORMAL position, check the voltage between WHITE/
BLACK and WHITE/RED wires to switch. If 120 V, replace the
switch.
1. With door closed, measure voltage between BLUE and
WHITE/BLACK wires on terminals #6 and #9 of the relay.
If 120 V, replace the relay.
2. Measure between the BLACK wires on terminals #6 and #9
of the relay. If 120 V, replace the relay. Measure between the
WHITE/ BLACK wire on terminal 4 and the ORANGE/WHITE
wire on terminal 7 of the relay. If 120 V, replace relay.
1. With door open, check for voltage between ORANGE/WHITE
door switch and neutral. If 120 V, replace the door switch.
2. With switch ON, check voltage between BLACK and WHITE/
BLACK wires to switch. Replace the switch if 120 V.
3. In the NORMAL position, check the voltage between
WHITE/BLACK and WHITE/RED wires to switch.
If 120 V, replace the switch.
1. Reposition switch assembly, bend metal lever if necessary.
2. Measure between BLACK/YELLOW and ORANGE wires on
"cycle reset" switch while timer is rotating. As the switch lever
drops into home position you should measure 120 V. If not,
adjust or replace the switch.
1. Check water pressure during fill, pressure must
be 15 PSI.
2. Repair or replace water inlet solenoid valve.
