Product review (5 stars): DIY Washer Repair
works just right and saved me a fortune in repair costs.  I was quoted $160 by local repair facility which doubled to $320 when they were advised that my washer and dryer were stacked.  That was just to walk in the door.  Fees for Length of service would be dependent upon how much time was required to do the repair and test it.  A couple friends helped lift the dryer off the washer for free, I replaced the necessary part, and machine has been working like new ever since.
