  • Dishwasher not draining properly
  • Water backing up into the sink
  • Bad odors coming from the dishwasher

Understanding the Dishwasher Air Gap

The dishwasher air gap is typically located under the sink, near the dishwasher. It is a small, cylindrical device with a hole in the top. The hole is connected to the dishwasher’s drain hose.

When the dishwasher drains, water flows through the drain hose and into the air gap. The air gap creates a break in the water flow, which prevents contaminated water from flowing back into the dishwasher.
