Brian S Fayetteville , AR February 14, 2020 Appliance: Whirlpool Undercounter Dishwasher GU3600XTRB1 Whirlpool Dishwasher Gu3600xtrb1: Would fill, heat and drain but not go into wash cycle. How to replace Circulation Motor. Ordered a new pump after looking at new machines for $600-$800 and watched the repair video and realized it was a very simple repair. Took the dish machine out of the cabinet on Sunday and removed the old pump. On Tuesday the new pump arrived and I replaced it following the instructions on the video. Was a very easy repair and the machine is working better than ever. It's actually much quieter than it was over the last year. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
