: Terry, I have a dishwasher, installed by a professional several years ago. At the time he isntalled it he told us we would have to periodiocally keep the vent cleaned out. We do not have a disposal...just a simple sink and the vent is installed next to the cold water tap. Anyway in the last few usings of the dishwasher I am geting water all over the counter top, how can I fix this, everything inside the vent is a white plastic. Just getting to old to be cleaning up unnecessary messes. Appreciate any help you can give me. Cheryl
There could be a kink in the DW drain hose or a clog restricting proper flow from the DW. Cleaning the air gap probably will not correct your problem.
Good Luck. e-plumber
