Kyle B Caldwell , ID April 08, 2015 Appliance: Whirlpool Undercounter Dishwasher GU2800XTVB2 Whirlpool Dishwasher Gu2800xtvb2: Wash motor failed (6 1 error). How to replace Pump And Motor Assembly. After pushing the start button, the dishwasher would try to start the wash cycle but would eventually time out. After running diagnostics it was flashing 6 times which meant it had something to do with the wash motor. I actually had a tech come out to make sure this is what was wrong and he tried replacing the board first, which turned out not to be the problem. After a $60 service call fee and no fix to the problem, I decided to replace the wash motor assembly. It took me about an hour to get the assembly switched out and the dishwasher fired right up when I was finished. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
