Robert P Folsom , CA March 27, 2022 The dishwasher was not draining completely. Pulsed when draining. Replaced the drain pump and flapper valve. Very easy job. Since I was doing this, I replaced the drain hose too. To have the complete drain system replaced. Replacing the drain hose took the most time, but still easy since I had the dishwasher out of the cabinet. Total time, from pulling it out of the cabinet to starting rinse cycle to check for leaks, 2 hours and no leaks, drains like new. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
