Default Dishwasher Drainage Question

I've searched and searched but found nada on this topic. Don't want to be redundant.

I've got an Whirlpool Estate dishwasher that does not drain completely. There's always a little water left over the drain grate. The hose leads to the disposal under the kitchen sink and has to travel along a 16" hose and upward, about 8-10" above the bottom of the washer.

During the draining stage I can see water flowing through the hose and it almost pulsates instead of flowing at a regular rate.

It's not a huge issue but just wondering how I can get more exiting drainage pressure. Any thoughts or ideas are much appreciated.

A premature "thanks."

You say that the drain hose only rises 8"-10"?

I would bet that you are getting backdrainage. Try routing the hose much higher, bringing it through the wall of the cabinet just below the countertop.
