Dishwasher - Cleaning Your Air Gap

The air gap is the chrome cylinder on the back of the sink. Not all areas require an air gap, so your home may not have one. The air gap prevents water from a clogged drain from backing up into the dishwasher.

To clean your air gap, follow the steps below:

  1. Remove the chrome cover of the air gap.
  2. Unscrew the plastic cap.
  3. Remove any material that may have accumulated.
  4. Check the hose from the air gap to the drain or garbage disposal to make sure it is not clogged.
