GE profile dishwasher won't drain

Not sure of the exact model number. The sticker is missing from the inside of the door. Owners manual lists EDW2020,30,50,60, GSD 5110, 12, 20, 20, 32, 14, 24, 34, GSD5310, 20, 30, 50, 60. Problem started of as intermittent. Had a repair guy come out an look at. He suggested the control board was bad and we would be better off buying a new dishwasher. I replaced the control board and it still did not drain. Then checked the drain tube to the disposal. It appeared to be about 75% plugged on the disposal end. Replaced the hose and it still did not drain. I think the hose got plugged/dirty during the 2 month we did not run the dishwasher but continuted to use the disposal. Then pulled the drain pump. It appears to run ok when you apply power to it while it is sitting on the bench. I can feel it vibrating when it is going through the drain cycle. Then replaced the check valve assembly and it still does not drain. Then opened the door during the drain cycle to ensure the spring loaded valve was down and water was available to the drain side during the drain cycle. I’m confused! Help.

I stopped it last night during the drain cycle. If I close the door and hit the start/reset button the pump will come on and the start/reset light blinks.

I ran it through the rinse cycle only and did not see any blinking lights at the end of the cycle. Iam going to pull the drain pump again and see if I can get it to pump water.

I think it is the pump. It will push water through the check valve assembly in to a bucket but it will not push it through the drain hose.

My neighbor just bought new machines and gave me their used neptunes. Just in time, my G.E.s are falling apart…The washer fills, then agitates only a few seconds and stops. When put on spin cycle it makes kinda a loud buzzing sound but does not spin. As far as I can tell it isn’t draining either. What should I do…I’m pretty mechanically competent but I don’t know where to start…Thank you…Steven
