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.

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
ForCustomerService:Call1‐866‐GOFAGOR–www.fagorcommercial.com| P.16
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

208V-240V found, replace circuit board.
Dishwasher RUNS
continuously in the wash

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).
ForCustomerService:Call1‐866‐GOFAGOR–www.fagorcommercial.com| P.17
SYMPTOM POSSIBLE CAUSE ACTION
Dishwasher RUNS.
WASH WATER NOT
REACHING REQUIRED
TEMPERATURE OF 150°F
Low incoming water
temperature supplied to the
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 >
180°F). If A4 is displayed, reconnect temperature
sensor. If A5 is displayed, replace temperature sensor.
Misadjusted/faulty
thermostat (Tt) Verify voltage to t-stat. If voltage has been verified ok,
check tank heater relay Ct
Tank heater relay (Ct)
