TROUBLESHOOTING

SYMPTOM POSSIBLE CAUSE ACTION

Dishwasher will NOT FILL

after the door is closed.

Power “ON” light (L1) is not

illuminated.

Service breaker tripped Reset. If the breaker trips again, contact an electrician to

verify amps or possible short.

Machine not connected to

power source. Verify the unit is connected to a hot (live) feed. Verify

voltage and proper phasing.

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 will NOT FILL

or reach the appropriate

water level after the door is

closed. Power “ON” light (L1)

is illuminated.

No water to machine Verify hose is not blocked or kinked, water valve is open

and pressure > 20 psi.

Machine not level Level machine. Legs are height adjustable.

Overflow tube not attached

or broken / missing O-ring. Check condition of overflow tube. Make sure O-ring is in

good working condition and in place.

Faulty door switch Verify the wiring at the switch for loose connections; if

no loose connections are present, replace the switch (Ip)

or the door relay (Cp)

Faulty fill pressure switch

(P1) Verify voltage at terminal 2 (brown) and GND. If no

voltage, P1 is possible stuck.

Faulty rinse/fill valve (V) Verify the wiring and proper voltage at valve; if correct

replace fill valve.

Dishwasher will NOT RUN

after the door is closed.

Power “ON” light (L1) is

illuminated and the unit has

completed the filling and

heating cycle.

Faulty fill pressure switch

(P1) Verify it changes position of the switch; on terminal 1 to

2 (fill), and 1 to 3 (heating) If not replace it.

Faulty Power/Start button

(St) Verify good connection between digital start buttons and

circuit board. If disconnected, reconnect and verify.

Verify circuit board fuse is If connected and still not

working, replace Adhesive Trim.

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 wash pump (MBL) Rotate the pump from the shaft flat head slot counter-

clock wise to verify free rotation. Verify that the wash

pump is getting power. If so, replace the pump.

Faulty start buttons Verify good connection between digital start buttons and

circuit board. If disconnected, reconnect and verify.

Verify circuit board fuse is If connected and still not

working, replace Adhesive Trim.

Rinsing temperature gauge

is lower than 180ºF. Wait until sanitized rinsing temperature reached a min.of

180ºF. Check out your incoming water temperature.

Recommended incoming water temperature is 140°F

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).

Dishwasher

Check out that incoming water temperature is at least

120°F and pressure is at least 20 psi. Optimal incoming

water temperature is 140°F and optimal incoming water

pressure is 25 psi.

Faulty thermostat (Tc) Verify that there is power on violet (vi) coming from Tc

to Tt (only applies after Tc has been satisfied or >

replace Drain pump (BD).

Faulty safety pressure

switch (P2), Overflow. Verify that the black rubber pressure tube is not kinked

or damaged (air leak). If so, replace black rubber

pressure tube. If not kinked or damaged, replace

pressure switch P2.

180ºF. Check out your incoming water temperature.

Recommended incoming water temperature is 140°F and

incoming water pressure is 20-25 psi.

None or too little

detergent being used. Make sure detergent to dish ratio is fallowed to

manufacturer specification. Make sure that the detergent

and rinse pumps have been adjusted and primed

(priming only applies to the rinse pump). Check for kinks

along the chemical lines. Make sure that the chemical

line brass filters are completely submerged below the

chemical level.

Dishes are not coming

out clean enough.

Improper loading or

overloading Read chapter on proper loading of dishwasher. Refer to

page 15 of this manual.

Washing and or rinsing

arms jammed or dirty. Check that arms rotate properly by spinning them

manually and that rinsing and washing nozzles are not

blocked or dirty. Clean if necessary

Clogged drain Remove obstruction from the pump and/or make sure

the drain hose is not kinked and flush out any debris that

may have been accumulated.

Machine not level Level machine by adjusting the unit’s legs accordingly.

Refer to page 6 of this manual

WATER OVERFLOW

FROM BOTTOM OF THE

DOOR

Excessive inlet pressure Install pressure reducing valve. Ensure flow is 20-25 psi.

EXCESS FOAM coming out

of the door.

Use ONLY commercial grade, low suds, liquid detergent

for commercial appliances. Adjust the amount of

chemicals being dispensed to the unit. Refer to page 14

of this manual.

Low water pressure, rinse

aid container is empty, air in

the pump and/or lines.

Verify that the min. incoming water pressure is 20 psi.

Verify that there is enough rinse aid left in the container.

Make sure that the rinse agent chemical lines are primed

and free of kinks.

Rinse agent not being

dispensed Detergent tubes not

placed properly inside

container/improper
