Does not dispense
ice and/or water.
Check LEDs on the
SensorSAFE control
board.
OFF OFF OFF Check circuit breakers and power switch. Restore power or
replace defective switch.
ON ON OFF Press clean switch on lower left side of electrical enclosure
to return board to normal operation.
Place cup under drop
zone (in front of lens)
ON OFF OFF Troubleshoot appropriate lens/sensor and replace if required
(see lens/sensor troubleshooting).

continuously.
Check LEDs on
control board.
ON OFF ON Troubleshoot appropriate lens/sensor and replace if required
(see lens/sensor troubleshooting).
ON OFF OFF If there is power on any output terminal 9WTR or WM) on
control board, replace board.
Board guide
LEDs, when illuminated, indicate the following: PWR (board power), CLN (cleaning, no dispensing cycle), ICE (ice
dispensing activated), WTR (water dispensing activated).
Terminals: LI (incoming power, hot), L2 (neutral terminals), WTR (power terminal for water solenoid), WM (power
terminal for wheelmotor), CLN (terminals for clean cycle switch).
Lens/sensor troubleshooting
1. Turn dispenser power switch off and remove splash panel.
2. Disconnect wires from WTR and WM terminals on board.
3. Gently remove sensor/mounting block from splash panel.
4. Inspect lens and sensor. Clean if necessary.
5. Restore dispenser power and test sensor by passing hand in front of sensor.
6. If LED on board turns on, sensor is operational. Re-assemble dispenser.
7. If LED does not come on, switch sensor leads on board and retest.
8. If opposite LED comes on, replace defective board.
9. If opposite LED does not come on, replace defective sensor.
