Keep your air gap vent functioning properly
Clean the air gap with a brush
Soak the bottle brush in household cleaner and plunge it up and down into the air gap.
An air gap prevents dirty dishwater from backflowing into fresh water lines. But over time, ground-up food and grease can build up inside the air gap and form a clog. If water squirts out the air gap’s vent holes or you notice a foul smell coming from it, it’s time to clean it. All you need is a bottle brush and some household disinfecting cleaner.
Yank the cover off the air gap and remove the snap-in or screw-on diverter. Remove any loose food particles, then clean with the bottle brush as shown. If you still have a water leak after cleaning the air gap, clean the drain line where it meets the garbage disposer or drain wye (aka “Y”).
