Whirlpool duet HE. MODEL GHW9460PL1 displays F H. Flow meter seems to work. Water valve too. Plenty of flow. Not the pressure switch. Nor hose. Hat could possibly be the problem?????
If it’s not a flow problem, other possible things are: Solution 1: Main Control Board Solution 2: Pressure Switch Solution 3: Flowmeter Solution 4: Wire Harness Go ahead and see if it runabout first unplug it for five minutes to allow it to reset and then see if the problem persists.
