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), SOL (power
terminal for dispense gate solenoid), WM (power terminal for wheelmotor), CLN (terminals for clean cycle switch).
Lens/sensor troubleshooting
Turn dispenser power switch off. Remove splash panel. Disconnect wires from output (WTR, SOL, WM) terminal(s) on
board. Gently remove appropriate sensor/mounting block assembly from panel by moving block sideways until edge of
block clears retaining tab of panel. Inspect lens and sensor assembly for foreign material and remove using non-abrasive
cleaner. Turn dispenser power on and test sensor by moving hands through activation area (no closer than 3/16"/1.9mm)
in front of sensor. If LED on board turns on and off, sensor is working properly and dispenser may be reassembled. If
LED does not come on, switch sensor leads on board and retest. If the opposite LED comes on, board is defective and
must be replaced. If LED does not come on sensor is defective and must be replaced.
