It seems to be a common problem that dishwashers, sooner or later, will leak massive water over the floor. I’ve been told that the drain line often requires some loop or arc in it to prevent a siphon effect, I believe…and far too often they are not installed with such. Also, some will argue food particles clog the line if you do not rinse your dishes.
Regardless, examining my dishwasher’s drain line, it appears to run uphill into the disposal under the kitchen sink…a common plan. But, drains typically work by gravity-flow, therefore dishwashers must have a pump in the drainline, correct? If so, how well does the pump handle food particles? Could the pump be the real culprit here to leaking dishwashers that don’t drain well? (I should mention there is a standing puddle in the bottom of my dishwasher at the end of a run.)
I know my parents had the same problem, but I forget what the cure is! I do recall that pre-washing dishes helped, but it’s hard to get all family members into that routine! - Jinx
