Eric D Loveland , OH April 06, 2014 Crud was collecting in the back of the dishwasher, wasn't draining right. Removed screen that covered the lower back section (great video on APP site). Unscrewed and cleaned the piston, but noticed the rubber part was in poor condition. Found part here, arrived quick, and replaced in less than 10 minutes. 67 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
