I have a 2010 dishwasher that is a TROOPER: gets things clean, and I can count on it. That said, the pump tends to go on a yearly basis. This is probably related to the fact that I don't load the dishwasher, my husband does, and he's indifferent to items that jam or damage the pump. Like glass and citrus seeds. I got to pick my battles, you see.
After researching the current state of the appliance industry, I have opted to try to keep my old ones as long as possible. I noticed that the manufacturer has discontinued this pump. I got two more just to be safe. I am also keeping the old broken pumps to refurbish in the future. I did my own car repairs in the days of carbureted engines, so I will definitely try to rebuild a dead pump if I need to, down the road.
I learned to change the pump by watching an appliance guy do it several years ago. Thank goodness I did. He's retired now, and no one else does repairs in our area. Takes me about 20 minutes of swearing on my belly in the kitchen with a flashlight and a screwdriver.
