Inlet Water Solenoid Valve
1. Test using the controller’s indicator lights. Shut unit off by holding the Off button for 3
seconds. Wait four minutes. Push and release the On button, observe the Water Solenoid
indicator light. After the unit drains the reservoir, the inlet water valve will be powered to refill
the reservoir. When it gets power, the indicator light will be ON. If the water valve does not
open to fill the reservoir when its indicator light is on, do a voltage check. Shut the unit down by
holding the Off button in for 3 seconds. Unplug the harness connection from the inlet water
valve. Wait four minutes. Push and release the On button to restart the machine. After the unit
drains the reservoir, the inlet water valve connection should receive full voltage. If it does, the
inlet water valve should be replaced. If there is no voltage, check voltage from the controller to
ground. The inlet water solenoid valve pin is 7. If there is voltage from that pin to ground, but
low voltage at the valve harness connection, the harness has a broken wire or poor connection
and must be replaced. If the voltage to ground is low, the controller should be replaced.
2. Test using an ohmmeter. Disconnect electrical power. Unplug coil from harness. Measure
coil resistance. If open, replace the inlet water solenoid.
