The Dishwasher has started leaking when the Dry cycle kicks in. I've had the
hose off to check for cracks and tighted the clamp just now. It's running
another cycle to check for leaks again. But ti just occurred to me that the
drain hose was backed up with water when I took it off. Do DW drains get
clogged? Would the back pressure cause a leak?

TIA

When mine leaked, it was the pump seal. New pump, no more problem.
