Waterbath circuit board operation
The temperature sensor is hard wired directly to the circuit board. The waterbath circuit board operates on 24
volts AC. The bath pump will run for 35 minutes whenever ice is dispensed or the bath calls for ice.
Optimal beverage temperature is controlled by the circuit board located in the electrical box. The board monitors
the waterbath temperature and holds it to a factory setting. When the Red LED is ON, the bath solenoid, auger
motor, wheel motor and bath pump are energized. Ice will be dispensed into the waterbath for 12 seconds, then
stop for 60 seconds. The pump will stay energized, and the circuit board will then monitor the water
temperature. If it is below the set point, the Green LED will come on, the Red LED light will go off, and ice will
not dispense into the waterbath. If the temperature of the bath is determined to be above the set point, the Red
LED will remain on. The circuit board has a delay of 60 seconds before more ice is dispensed into the
waterbath.
LED indicators:
Green – the waterbath is at the set temperature.
Red – the bath temperature is above the set temperature and the bath is calling for ice.
Flashing LED indicators:
Flashing Red and Green – the circuit board has gone into an error mode:
Alternate flashing – circuit board has power and is waiting for hopper cover and dispenser top to be
replaced.
Simultaneous flashing – the waterbath did not reach set temperature in 40 minutes. Reset this error
mode by turning power off, removing top lid, drain pan or rear lid.
