SYMPTOM POSSIBLE CAUSE ACTION
Dishwasher RUNS
continuously in the wash
cycle or not rinsing.
Faulty Circuit Board Make sure power is being supplied to the board. Check
for loose wiring harness connections. Check circuit board
fuse. Check voltage between R (brown) and N (blue). If
208V-240V found, replace circuit board.
Dishwasher RUNS
continuously in the wash
cycle or not rinsing.
Faulty Circuit Board Make sure power is being supplied to the board. Check for
loose wiring harness connections. Check circuit board
fuse. Check voltage between R (brown) and N (blue). If
208V-240V found, replace circuit board.
Faulty Operating t-stat
(Tc)/Faulty Circuit Board
Verify rinse gauge temperature is above 180°F. If above,
replace circuit board. If rinse temperature <180°F replace
Tc thermostat and/or boiler element and heater relay. If
A4 is displayed, reconnect temperature sensor. If A5 is
displayed, replace temperature sensor.
Faulty rinse/fill valve (V) Verify the wiring and correct voltage at valve; if correct
replace fill valve.
No water to machine. Verify hose is not blocked or kinked. Verify the inlet water
pressure is at a min of 20 psi and max 25 psi.
Clogged or obstructed
rinse arms
Remove and clean rinse arms/nozzles.
Dishwasher FILLS slowly
and/or rinse is weak.
Poor water pressure Verify the inlet water pressure is at a min of 20 psi and
max 25 psi.
Hose strainer is clogged Check strainer or any filters installed.
Bad rinse/ fill valve (V)
Valve can be clogged
causing poor flow.
Disconnect hose from fill valve and check filter screen
inside for debris. Replace rinse/fill valve as needed.
Temperature gauge in
front panel is defective.
Check temperature with a calibrated thermometer at the
corresponding temperature sensor location. Replace
temperature gauge as needed.
Dishwasher RUNS.
RINSE WATER NOT
REACHING MINIMUM
TEMPERATURE OF 180°F
Misadjusted/faulty
thermostat (Tc)
Verify rinse temperature probe sensor is properly inserted
inside probe well. Replace Tc thermostat and/or boiler
element and heater relay. If A4 is displayed, reconnect
temperature sensor. If A5 is displayed, replace
temperature sensor.
Faulty high limit stat (Tl) Reset thermostat by depressing red button. Replace if
necessary. Make sure heater relay (Cc) is working
properly (not stuck in or out) and Tc thermostat is cutting
off below 195°F
Faulty heater relay (Cc) Verify voltage at heater relay coil (A1, A2), solenoid
closes when receiving voltage. If not, replace heater relay
(Cc).
Faulty Boiler element (Rc) Ohm out element check for continuity; if open, replace
heater (Rc).
