Hi, I'm a relatively technical user and am capable of following technical directions and replacing parts.

I have a Kitchenaid KDTM354DSS4 that doesn't fully drain. After the cycle ended, there was still water inside of the dishwasher that hadn't fully drained.

I manually drained all the water out of the bottom of the dishwasher, then disconnected the hoses from the drain and the drain pump, and was able to blow air through - the hose is not blocked. There was quite a bit of soap build-up, but nothing I saw that was especially obstructive that I believe would have prevented the dishwasher from draining properly.

I then started a "cancel drain" cycle, where I can see the impeller spinning inside of the drain motor. It sounds normally once it starts spinning.

Is there always a quart or so of water in the bottom of the dishwasher, or should it be completely dry at the end of a cycle?

Is it possible the drain motor works, but is not sufficient to completely drain the dishwasher?
