A couple of days ago I noticed water flowing from the bottom of the cabinet housing my dishwasher. This happened all through the wash cycle. I open up the bottom panel of the dish washer and notice water dripping from a "motor type" assembly (the assemble is just beneath the spinning arms inside the dishwasher. How do I fix this problem? Do I need to replace a part (like a seal) and if so, how do I do this? Thanks for any help. My Diswasher is a GE model 500 and about 7 years old.
