Product review (5 stars): before you buy this part....
I did not buy this part but I wanted to share my story so hopefully your problem is as simple as mine. I have a 6 yr old Kenmore duet washer. No problems whatsoever until yesterday I bought Arm and Hammer for HE machines instead of my usual Tide that I've used for years. I turned machine on and it seemed to start up like normal. I went back around 20 min later and where the time remaining is,it read the message "suds" followed by the code F35. I googled it as fast as I could and came up with everything from issues switching laundry soap" the air hose being cracked or unattached to replacing this sensor. I assumed it was the sensor so I called Sears to have a tech install one that day. Ok long story short I ended up canceling my appt with sears because I was confident I could buy the part and install myself. Well the tech called me anyway because he didn't get the message the appt had been canceled. I explained everything to him and he asked me if I cleaned the filter....Im like what filter??? Ok so maybe it was the first thing to check but if any of you didn't know you had a filter you do! On my machine its in the panel with 3 screws below the door where you load clothes. My filter had 3 pens, 20 something hair pins, hair ties, money, and 6 years of gunk. It was a duh moment but maybe my mistake can save you money. Also there is a trouble shooting manual taped inside that panel with all the codes you can imagine. What a convenient place.
