The cold part of the water inlet/mixing valve assembly (part #8181694) is not working. Disconnect power to the machine then remove the three screws at the back of the top panel securing it to the cabinet. Once the screws are removed, slide the top panel to the back of the machine then lift it off.
Check the valve solenoids using an ohmmeter. Disconnect a wire from each of the solenoids then measure the resistance between the terminals of each solenoid with the ohmmeter set to X100. The resistance of the solenoids
must be almost identical at about 800 ohms.
Check the continuity of the solenoid wiring harness to the central
control unit. Make sure the connector at the central
control unit is properly seated to ensure good connection. The 4-wire
valve solenoid connector is the fourth connector from the left (facing the front of the washer) of the
central control unit.
Disconnect the solenoid wires from its terminals if the resistances of the solenoids found above are the same and there's a good connection between the solenoids and the central control unit. Cleaning the terminals will help. Reconnect the solenoid wires in place of the other solenoid wires, and then start a new cycle to check if the temperature of the water coming into the washer changes.
Replace the water inlet/mixing valve if one of the following is observed:
- The resistances of the valve solenoids are not the same; one solenoid is open, and the connection between the solenoids and the central control unit is okay.
- The water temperature does not change after the hot and cold solenoid wires are interchanged.
Remove the fill hoses then remove the valve assembly mounting screws. Disconnect the valve assembly outlet hose then remove the valve assembly from the cabinet. Connect the outlet hose to the new valve assembly then mount it into position in the cabinet with the mounting screws.
Slide the top panel into position then secure it the three screws to the back of the machine.
