Kenmore HE5T 110.47088600 F20 Error Code
« on: May 15, 2013, 07:16:52 AM »
Working on a Kenmore Elite HE5T 110.47088600 with F20 error code. Code is "insufficient inlet flow or pressure". Cleaned the inlet screens in the inlet water valve and even removed them. Washer would fill for 30 seconds then throw the code. Took flowmeter off and tested resistance while blowing air through it. Resistance changed as airflow increased/decreased. Removed pressure switch hose and blew through it and found no leaks. Removed pressure switch and blew in it and it clicked indicating operation. I do have a pressure switch and a flowmeter on order. Ran the diagnostic check last night and everything seemed to check out fine. Also tried a wash cycle last night and this time it ran for  longer (6 minutes?) before throwing the error code which suggests it is the pressure switch. I will try the flowmeter and pressure switch and if that does not fix it, what is the next logical failure?

I would inspect the air trap in the back where the pressure switch hose connects to the tub. It can get clogged with gunk and cause an F20 code.

I did pull the hose off of the pressure switch and blew through it from the top and heard water gurgling/bubbling down where it connects.

The last one I ran into with that code had a bad flowmeter. Although it tested good, after I replaced it all worked normally. I about pulled what little hair I have left on that one.....

The pressure switch hose may have a pin hole in it. This is a common fault of these hoses. A rub abrasion can occur.
Hose is cheap.
Replace it.

This washer is again doing the same thing, giving the F20 error code but it is intermittent. It did it 3 times 2 days ago all in a row and then ran fine after that. 8 loads later it is doing it again. I checked the same stuff again - blew through hose and checked for leaks, blew through pressure switch, ran diagnostic test, and adjusted the position of the flowmeter thinking it had to be at a certain angle to read correctly.
