Customer Questions and Answers for Water Inlet Valve by Whirlpool

Hello John, As per the tech sheet: NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED If, after 30 seconds during Diagnostic Test, less than 3.3 oz (0.1 L) of water has entered the machine, or if during a cycle, the maximum fill time of 13 minutes is exceeded, the valves will be turned off and the error code will be displayed. Press PAUSE/CANCEL twice to clear the display. Possible Causes/Procedure
If there is no water in the unit: – Make sure that both valves at the water source(s) are turned on all the way. – Check for plugged or kinked inlet hoses or plugged screens in the inlet valves. – Verify inlet valve operation.
If there is water in the unit: – Verify that the pressure switch hose is in good condition and properly connected to the tub and pressure switch. 1. Unplug the washer or disconnect power. 2. Verify there is not a siphon problem. 3. Verify wire harness connections to inlet valves, pressure switch, and Central Control Unit (CCU). 4. Check all hoses for possible leaks. 5. Plug in the washer or reconnect power. 6. Verify pressure switch operation (run diagnostic test). 7. Verify CCU operation by running a Diagnostic Test or any cycle. Details on the diagnostic test are included on the tech sheet found on the unit. This is normally located behind the lower kickplate of the machine in a plastic bag.

Emmitt, You will want to check to make sure that when the unit is calling for water that there is 120 vac to the water valve. If there is power then the water valve would need to be replaced.

Hello Fred. Check the wiring harness and make sure it was not damaged. If not, then test for power to the cold water valve. If there is power there, and no cold water, replace the valve. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
