I bought the new part and installed it fairly easy. Drained the unit. Tilted the unit on its side and un-screwed the screws holding the pump in place. Then un-fastened the hoses going into the drain pump. Put the new one into place and tested the unit to see if it would work. And it did. Saved big by not having someone come out and tell me what I already knew. Fixed in under an hour. Would have been faster with another pair of hands. Works better than when I bought it new. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
