I followed the youtube directions and checked the drain tubes first and found no blockage. Then I took off the drain pump which took all of 10 minutes and found that it had a broken fin on the impeller. I ordered the part from AppliancePartsPros.com and received it the next day. I put the new part in that day and the dishwasher has worked perfectly. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
