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