Product review (5 stars): Fixed the dreaded F20 error code!
I have a Maytag Epic Z washing machine with the dreaded F20 error code.  Sometimes it will go through a wash cycle just fine, other times it will stop with 21 minutes remaining and sometimes it would stop with 1 minute remaining.  I did all of the troubleshooting that I could find on the web and it lead me back to the water intake valve, the pressure switch or the pressure hose.  When I observed the wash cycle, you could hear some water filling up the drum but the clothes didn't look wet.  The pressure hose looked good me.  I tested both the pressure switch and intake valve for continuity and they both passed.  So I took a chance and purchased this part.  It fixed my problem.  The washer sounds much different now.  There's more water coming into the drum and it's going through a full cycle without any issues now.

The part arrived fairly quickly and was half the price on amazon.com so I purchased it here instead of amazon.ca.  Thanks!
