Whirlpool duet steam giving error code f20 - Whirlpool Duet GHW9150P Front Load Washer

I have finall fixed the f20 error. It has to do with the washer protesting that it is not getting enough water either from the hot or cold intake or both. This can be caused by many things including simple stuff like not turning both water valves on, Super low flow pressure, or screen filters being plugged with particulate. If all of these check out, then you have to look inside the machine. Most of the remaining f20 errors are caused by the following defective part: Whirlpool Washer, Water valve #8540751.
This is the housing that you screw your hot and cold water hoses into on the back of the washer. The water flow and temprature is controlled by two solenoid energized valves that turn the hot and cold water on and off. In many cases, one or both of these solenoids sticks intermittently, causing water temperature and volume problems that trigger the f20 error. In troubleshooting the problem on a warm water cycle(uses both hot and cold water), the hot water would only flow when I applied hand pressure to the hot water solenoid and flexed the electrical connection durring the fill cycle. It responed by working fine as long as I maintained pressure to the connection, and then failed when pressure was absent.
This part sells for under thirty dollars, is the size of a baseball, and can be replaced in less than an hour with a few simple tools, good luck

I am a tech and I was worried about the fix on this whirlpool duet steam the f20 error code could have been many thing even though the flow meter voltage meter on it, it out to be good it was bad. I replaced it and it worked fine.
