No Water Fill Troubleshooting - Error 4E

Measure the coil in the Inlet Valve. Remove the connector before measuring. A

good valve winding measures ~ 1200 Ω

Check whether the Inlet Valve is operating normally. Check the operation of the

Inlet Valve by measuring 120VAC across it while it is operating.

Check the Inlet Valve Relay for 120VAC. Check the voltage between the white wire

of the Main board CN1 Pin 1 and the brown wire of CN14 Pin 7.

For a no water fill problem check the obvious first. Make sure the water supply is

turned on. Check the drive voltage to the water inlet valve from the main board.

This should be 120VAC so care must be taken. If the voltage is present at the

board check it at the valve. Check the resistance of the valve windings which

should be ~1.2K Ohms if normal, check the wiring harness and also check for lose

connections.

Use the service and test procedures to manually turn on this device.
