Component Tests
Dual Probe Test
If lack of water persists, check the probe as follows:
1. Turn on the power and water supply.
2. Check inside the tank to make sure the water is
below the Probe.
3. Pull the BLUE wire and terminal OFF the Probe rod.
If water still does not flow after the wire is
disconnected from the Probe, the problem may be
in the Tank Control Board.
4. If water starts flowing into the tank, the Probe may
be grounded, due to excessive liming. Check with
Ohm meter. Clean probe.

Water Inlet Valve Test
1. Turn power OFF. If the water level rises inside a
partially filled tank, the Water Inlet Valve is leaking.
2. Disconnect wires from the Water Inlet Valve coil and
connect a 2 wire line cord to the terminals. Plug it
into a 115V outlet. If water flows in and stops when
you pull it out, the Valve is working correctly.
Repeat this test a few times. The problem may be
in the Probe or Water Level Control Board.
3. If the water does not flow in when the cord is
plugged into an electrical outlet, the Solenoid coil
may be damaged, opened or the valve may have an
obstruction preventing the water from flowing in.
Clean or replace it.

Out of Product Sensor Test
1. Remove Hopper from cabinet, place the palm of
your hand up against the 1 inch diameter round
sensor at the back of the hopper chamber.
2. Listen for relay clicking on and off as you move your
hand towards and away from the sensor.
3 If relay clicks, system is operating OK.
4 Replace with a full hopper and listen for the relay
click.
5 If all this checks out and the out of product light
does not go off, then there must be defective
wiring. See wiring diagram.
Dual Probe Liquid Level Controller Test
(For models manufactured 2015 and prior)
Check the Controller as follows:
1. Make sure there is power input to the Controller at
the terminals AC1 & AC2
Your voltmeter should read 115 Volts. It should read
the same at terminals AC1 & FILL when the water
level is low. This is the output power to actuate the
coil of the Solenoid Valve to open it. The lack of
voltage at terminals AC1 & L-LEVEL or H-LEVEL
indicates that the Controller is not working
properly.
2. Make sure all wire connections are tight, including
ground.
3. If after this, the Controller is still failing to open the
Water Inlet Valve, replace it.
