Frigidaire dishwasher not draining completely

My dishwasher does not dry completely, so I opened up the bottom inside and finds there is water left there. dishwasher still washes and heat up and I see the pump can get water out however the water will flow back.

I took a picture of the water

I’m not going to type this again, so I suggest that those dealing with partially-performing dishwasher draining systems read this:

Thanks John!

This is the link to my dishwasher manual:

I can’t seem to find water valve for draining, in my case, is it integrated in the drain motor, do I need to replace drain motor?

Thanks a lot!
