Dishwasher not draining properly

Hi all,

I ran the dishwasher overnight and woke up to water in the base of the tub.
I sucked out that water and did a rinse only cycle. This delivered the same
results. I pulled the front base panel and removed the pump. Is there any
way to test the pump to see if it is operational? Also my father told me to
check the drain solenoid but according to the schematic the is no solinoid
on ths model. The pump sounds like it is running but makes a buzzing sound.

Thank You

UPDATE!

I discovered a clog in the drain hose to the disposal. One problem fixed.
Discovered 2 leaks in the process.

  1. Heating element where it penetrates the tub (loose bolt)
  2. Base of the door. Still trying to figure this one out.
