Whirlpool Washer Error Code F20 Troubleshooting Front Load Washing Machine
This link will probably not help you ... but it does reinforce that many people have the same problem of trying numerous things ... but the code keeps coming back ... sounds very frustrating when you are trying to troubleshoot the issue yourself...

Whirlpool error code F20 appears when no water is detected entering the machine or if the pressure switch trip is not detected. The pressure switch is the part of the machine that monitors high water pressure. The washing machine automatically cancels the wash cycle during an F20 error. Wonder if it has additional issue since it won’t stop quality Appliance repair Stuart Internet answer.

recheck water supply. try different wash cycles see if you have same problem.

F20 is a No Water Detect error.
It is an indication that you either have no water coming into the washer, or very little water at all. If the pressure switch has not tripped after 6 minutes, the error code is displayed. This can be a potential problem with the following:

* If you have NO water in the wash tub, check the following:
- Inlet water valve may be clogged. Clean inlet screens if necessary.
- Make sure water taps are on.
- Check inlet hoses for kinks or clogs.

* If you HAVE water filling the wash tub, check the following:
- Make sure you don't have a siphoning problem. Click the following link for instructions: Duet_Service_F20_error

MY WASHING MACHINE IS FLASHING F20.. WHAT DO I DO?

I believe F20 may point towards a control unit failure.
You could try disconnecting it from the mains supply for a minute and plug it back in.
Hope this helps

That code means "No water or Insufficient water supply" Check the water supply valve, the fill hose screen for debris... Good luck let me know if that solved it..
