I have water leaking into my basement. I see water on the cement. I also see water stains on the wall. When I go upstairs my dishasher is right above it and I had it on. I can't repair this myself. Do I call a dishwasher repair person for this? A plumber? I don't know how to do this myself. A service call isn't cheap, so I don't want to guess and call the wrong repair person. When I look under my sink, I do not see any water leaking. I don't know about pipes. However, my sink isn't running, but my dishwasher is on and I see fresh water.
