When doing a load and selecting Cold/Cold temps, I am only getting HOT water. All the temp settings are only allowing HOT water to flow. I have a Whirlpool GHW9150PW0 model. Anyone know why this is?

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:

1. 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.
2. The water temperature does not change after the hot and cold solenoid wires are interchanged.
