Cheryl S Coral Springs , FL August 31, 2020 Appliance: Whirlpool Undercounter Dishwasher GU1500XTLQ0 Whirlpool Dishwasher Gu1500xtlq0: My Whirlpool dishwasher was not draining. How to replace Dishwasher Drain Pump. I cleaned out the dishwasher and found the check valve was bad. The Dishwasher started draining ok, until it would stop draining again every 2 weeks. I would vacuum out the water, check for clogs and found nothing. So I checked with Appliance Parts Pros for videos. Found that there were only a couple of things that could be bad. So by process of elimination, I ordered a NEW Drain Pump. Being 58 year old woman, I figured how bad could it be? Actually not bad. I watched the video and did exactly as it said and now my dishwasher is up and running great!!! Thank you Appliance Parts Pros for the video and such great parts. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
