Product review (5 stars): Exactly what I was hoping for!
My 8 year old Whirlpool Duet dryer was repeatedly giving me the F35 & SUDS error so I took a chance and paid the $100 to see if it would save me a service call and/or a new washer.  I followed the instructions I found on Youtube.com and in about 30 minutes I had it replaced and the washer was back to running again!

In fact, I was so happy with the fix I took apart my dryer and replaced the belt and pulley system.  I was a much larger project that took a couple of hours, but in the end I have a washer and dryer that run like new!
