TROUBLESHOOTING SECTION
7
WARNING:
Inspection, testing and repair of electrical equipment should be performed only by qualified service personnel. Certain
procedures in this section require electrical tests or measurements while power is applied to the machine.
Exercise
extreme caution at all times.
If test points are not easily accessible, disconnect power, attach test equipment and reap
ply power to test. When replacing electrical parts, disconnect power at source circuit breaker.
Possible Cause
Action
Service disconnect switch off or faulty.
Turn disconnect on.
Branch circuit breaker tripped/fuse blown.
Reset or replace.
Loose or broken connection to dishmachine. Tighten or replace connections.
Door switch shorted out.
With the door open, check for voltage
between ORANGE/WHITE door switch and
neutral. If 120V, replace the door switch.
Faulty control relay.
With the door open, check for voltage
between connections #9 & #3 on control
relay. If 120V, replace control relay.
Faulty "cycle reset" microswitch in cam
timer.
Replace microswitch.
Faulty cycle reset cam microswitch.
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 120V, then the switch is open and
should be replaced.
Faulty cam timer motor
If cam timer is not rotating, check the
voltage to the motor. If voltage is present
when the door is closed, replace the motor.
Faulty control relay.
Check the voltage across contacts #9 and
#6. If 120V when the door is closed, replace
the relay.
Faulty NORMAL/DELIME switch.
In the NORMAL position, check the voltage
between WHITE/BLACK & WHITE/RED
wires to switch. If 120V, replace the switch.
Open door switch.
With door closed, measure voltage between
BLUE and WHITE/BLACK wires on
terminals #6 & #9 of the relay. If 120V,
replace the relay.
Faulty control relay.
Measure between the BLACK wires on
terminals #6 & #9 of the relay. If 120V,
replace the relay.
Measure between the WHITE/ BLACK wire
on terminal 4 and the ORANGE/WHITE wire
on terminal 7 of the relay. If 120V, replace
relay.
Faulty door switch.
With door closed, check for voltage between
WHITE/BLACK and ORANGE/WHITE wires
to the door switch. If 120V, replace open
switch.
Machine will not run in "ON" position or 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 unless
cam timer is moved off the "home" position.
Machine will not cycle in "ON" position,
works in Delime mode.
Symptom
Dishmachine will not run, no voltage at
wash relay terminals L1 and T1.
