Excess water from drain pump hose after each load

I have an LG WM3050. I have to drain the water from the drain pump hose after every load, and it drains at least 2 cups. If I don't drain it, water ends up on floor under machine on next load. I took the washer apart, checked all the hoses, and replaced the drain pump with a new one. Still happening. There is no water left in the tub when load is finished, and clothes aren't too wet, so I know the water is clearing the tub. Anyone know what could be causing this problem?
