The long fill error means that the washer is not detecting water coming into the machine properly, it may be getting water but it is still taking far too long to fill.
- Check your water supply, make sure you have water pressure to the washer.
- Make sure the supply hoses are not kinked
- Remove the hoses and check for stopped up screens (some water supply hoses have screens)
- Check the screens on the water inlet valve for debris or blockage that would slow water flow.
Check connections from tub to air trap, air trap to pressure hose, and pressure hose to water level sensor. Is pressure hose pinched, kinked, plugged, or leaking air?
If none of that seemed to be the issue then you will have to do some tests with a ohm meter.
Whirlpool Duet Washer Water Inlet Valve Test
- Disconnect the power to the machine.
- Remove the top washer panel.
- Unplug the wiring connectors from the water inlet valve and check the valve coil resistance across the terminals. Resistance should be 890–1.1k Ω. If resistance readings are outside the range or open, replace the valve assembly.
- If the resistance is good then check for voltage using a volt meter set to AC. you will need to do this while power is on to the machine and after you have started a cycle, it should be supplying voltage to the water valve to allow water in. If it's getting voltage and still not letting water in replace the valve. If you do not have voltage then you will need to do a water level pressure switch test.
Whirlpoool Duet Washer Water Pressure Switch Test
1. Check the functionality of the water level
sensor by running a small load cycle. The
valves should turn off automatically after
sensing the correct water level in the tub.
The following steps assume that this step
was unsuccessful.
2. Press START/PAUSE to stop the cycle and
then press POWER. The cycle will cancel and
drain the water from the tub.
3. Unplug washer or disconnect power.
4. Remove top and rear panels to access tub,
air trap, and pressure hose connections. Water
level sensor is located at top right rear of cabinet.
5. Check connections from tub to air trap,
air trap to pressure hose, and pressure hose
to water level sensor.
6. Check to ensure hose is routed correctly in
the lower cabinet and not pinched or crimped.
7. Verify there is no water, suds, or debris
in the hose or air trap. Disconnect hose from
water level sensor, clean air trap and remove
and blow into hose to clear water, suds,
or debris.
8. Check hose for leaks. Replace if needed.
9. Plug in washer or reconnect power.
10. With a voltmeter set to DC, connect black
probe to ACU connector J28, pin 1 (GND) and
red probe to J28, pin 4 (+5V [Vcc]).
If +5V DC is present, replace the water
level sensor. (Before replacing the sensor,
make sure that there is NO water remaining
in the tub or there will not be an accurate
water level measurement and an error code
may appear. Drain the tub by running a
drain & spin cycle with the sensor plugged
into J28 but with the hose removed).
If the pressure switch tests good then you will need to replace the main control board.
