Hi There
i just want to say Merry X-mas and a Happy New Year. i found this for you and i hope this will get you in the write direction.
F/H No water detected entering machine or Pressure switch trip not detected.

If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.
Or
If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.

Press PAUSE/CANCEL twice to clear the display.

• If there is no water in the unit:
  1. Make sure that both valves at the water source(s) are turned on all the way.
  2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
  3. Verify inlet valve operation
• If there is water in the unit:
  1. Verify Drain pump operation
  2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
• Verify there is not a siphon problem
• Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU)
• Check all hoses for possible leaks
• Verify pressure switch operation
  
• Verify flow meter operation
• Verify CCU operati

Thank you for writing to fix ya.

Hi there,

Well to Reset the error message as follows: To cancel the error message, turn the rotary selector switch to "Stop/End" or press the "Start/Stop" switch for approx. 5 secs. Then switch the appliance off and then back on again. 

If resetting not work then you can check that the stopcock is opened fully or whether the water inlet hose is kinked. Check that the water inlet filter is not clogged and clean it, if necessary, as described in the operating instructions. Check that the drain pump is not clogged.

Good Luck!!

On a Whirlpool ADP4731 dishwasher, try this...
Double check that the under-sink valve is open, providing hot water to the dishwasher.
If it is, the water inlet valve should be checked for proper operation.
The F4 error code means "drainage fault" which should be checked after the water inlet problem has been resolved.
Good Luck!

IE is inlet error, displayed when "Not reached to the normal water level in spite of 10 min. water supply"

Possible cause:

• The Water Supply Tap is closed.
• The Water Supply is shut off.
• The Inlet Hose is kinked.
• The Water Pressure is very low.(below 10 psi)
• Inlet Valve is OK?
• The filter of Inlet Valve is clogged by impure water.
• The Hall sensor is OK?
• The Impeller of Air Guide is bound.

Remedy:

• Cut power by tripping circuit breaker or unplugging power cable for ten minutes.
  
• Take action on Water Supply device.
• Measure the electric resistance of Inlet Valve. (950-1300 )
• Clean the filter of Inlet Valve.
• Check the frequency of Inlet Water by the Test Mode.
• Replace the Air Braker.

You probably have this solved by now but for others who read this as I did.............
F-20 means
“F20” on display
(Water Inlet Problem—no water or insufficient
water supply) Select PAUSE/CANCEL twice to cancel the cycle
Unplug washer or disconnect power. Check the following: Are water faucets completely turned on?
Are screens at inlet hose connection to washer
clogged? Are water inlet hoses kinked? Are water inlet hoses frozen?
Hope this helps everyone else as it did me, thanks

Check the inlet strainer at the bottom of the machine for blockage.



Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

F4 is a water inlet fault. It doesn't make sense if you have this fault indication with water flowing into the unit. Does the dishwasher drain properly? Usual suspects for an F4 indication would be a clogged inlet line, water supply turned off, bad fill valve, or a control board failure. Let me know if this helps, or give me a little more information on what you have done to correct so far.
