Soap does not completely empty

Soap Dispenser Issue:
Make sure there isn't anything in front of the detergent drawer that would restrict that door from opening, then if that is not the problem.. try cleaning that drawer with white vinegar to remove any soap scum that might be causing it to stick.. and try using a liquid dishwashing detergent or about 3/4 of what you normally put in there as powdered.

Drain Issue:
I suggest you check the drain filter to make sure it is free of food by products that would limit the drain process. If that isn't clogged, then check your drain line for a kink in it. Make sure that the place it drains into is not the limiting factor ( such as a clogged garbage disposal) If you don't find anything obvious in terms of the filter , drain hose or your house drain then you mave have a faulty or clogged pump..
