Water is coming out vent at top of sink from our ge dishwaser. Can anyone tell me what is causing this and how to correct it?
I am assuming that you are referring to the air gap.
Could be that you have a plug in the drain line between the air gap and the house plumbing, usually where the drain hose connects to the plumbing.
Also the air gap may need cleaning some come apart others do not.
Could be the air gap is shot.
