Robert E Egg Harbor Twp , NJ December 21, 2020 Standing water at the bottom of the dishwasher. I replaced the check valve, GE part for about $16 and all was great in the universe again. very simple fix, 4 screws and a plastic cover. I guarantee if I called a repair man this would have been a $200 service call. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
