Product review (5 stars): F35 problem solved!!!
My three year old Whirpool Duet was giving me a "suds" and "F35" error message for weeks.  We tried unplugging the washing machine, took the bottom front panel off and emptied out the hose and made sure there was no obstruction and finally called a repairman to fix the problem.  They quoted us $300+ to fix the washing machine.  I refused to pay that much.  Finally, we saw a Youtube video and figured we needed this part.  With nothing to lose, I ordered it.  It arrived two days later and it took my husband about 10 minutes to change out this part.  The most time consuming part was taking the original part out of the washer as it was a little tricky with the other mechanics in the way.  After replacing the part, we started a load and voila, no more error message!!!  This was definitely way less expensive than getting a repairman to fix it or buying a new washer.  If you have the F35 error message I would definitely try this fix.  But make sure you order the right part# for your washer.  There are several of them.

I'm a very happy mom now!!!
