This week I started noticing puddles on top of our basement dryer whenever running the dishwasher directly above it in our kitchen.
The wood in the basement ceiling above the dryer is damp and has a couple holes in it.
There is no sign of water on the kitchen floor by the dishwasher, although I of course have not pulled the dishwasher out.
Before I call in professional help, what are some things I should check for in the dishwasher?
