Kelly H Littleton , CO January 03, 2022 On my Bosch 800 series. I was getting e:15 and the drain pump would run. I noticed a small drip coming from the inlet valve housing. I replaced the inlet valve and a fill hose and dried up the water in the pan. The error was resolved and the dishwasher runs normally. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
