I knew nothing about dishwashers and am a new homeowner. Quick google search suggested the a problem with the drain pump or blockage in the drain hose. I bailed out the remaining water (about I4 inches in tub), unplugged power and water connections, and turned tub in its front. I didn't realize there was quite a bit of water still left in the tub that I couldn't see. made a bit of a water mess but 5 towels later it was fine. I located drain pump is on bottom of tub and removed it. I got into the actual pump to see if the propeller could freely spin. It was clearly blocked, so I ordered a new pump from AppliancePartsPros.com (make sure you get the right one--there are many different kinds). AppliancePartsPros were AMAZING. my standard delivery got to me in less than 2 days and with my email confirmation they sent me a very easy to follow video of their own guy replacing the same exact drain pump I ordered. The fix took me about 15 minutes and I was up and running. HUGE brownie points from the wife, as we have two very young kids that go through clothes very fast.
