Kenmore washer model 110.4757164 :F21 and sud
« on: March 26, 2019, 11:00:26 AM »

My customer has this front loading washer,intermittently draining,sometimes showing  F21 or sud.I cleaned the filter which was already clean.I found out the drain hose of the washer was inserted way too far into the wall drain pipe.So I pulled it out leaving 14"inside the wall drain pipe.Tested a cycle,it worked ok.The next cycle ,sud showed.No soap was put in for the last 3 wash or rinse.So it was not the real sud that caused the "sud" indication.I thought a long drain time could also cause it to show "sud".So I told the customer I have to replace the drain pump if F21 or sud showed again.Would that be the correct thing to do?

Might look at cleaning the pressure dome.  It has caused some issues with the pressure switch being able to determine the water levels.  Hope this helps.  Let us know how it works out for you.

replaced multiple pressure switches on those when it sets off that error; usually fixes problem
