My model number is DU960PWKS1. I read the linked thread below carefully but I believe there are some differences in the parts for my model.

It does not appear to have a check valve flap for instance. It has three check balls instead if I’m reading the parts diagram correctly.
I had a technician come out and check the unit, two in fact. One of them looked at the dishwasher and indicated that the likely cause was an obstruction in the drain hose running from the unit to the disposal, which is quite long. There’s no obstruction in the air gap because I used a little trick I saw online were you blow through a cardboard paper towel tube and could feel the air coming through into the disposal. I will admit that there’s a slight kink in that hose as it bends around to come into disposal unit. As I recall I installed this disposal myself and I’m not an expert plumber by any means!
The second technician vacuumed out the drain line and said that there was no obstruction there so he advised that if there were further problems I probably need a new unit. He said that sometimes the pump motor, and this dishwasher is 13 years old, can still work but just not have the same power that it did before. I found that kind of dubious but he was the expert.
I just now pushed the drain button and the small amount of standing water at the bottom of the dishwasher did in fact drain out. So I’m wondering if the problem is the drain valve as described in the thread linked above.
I have not gone through any of the other steps in that thread such as dismantling around the pump but again some of the parts might be a little different. So any input or advice would be appreciated.
FIXED - Whirlpool Quiet Partner II drain problem (Model # DU1055XTVQ2)
I have an older Whirlpool Quiet Partner II that will not drain. Wash cycle runs normally, but the basin is full of water at the end of the cycle. For a while the dishwasher was not completely draining, with some water left in the bottom. A second push on the Cancel/Drain button would remove...
