Water Coming Out of the Dishwasher Air Gap

When the dishwasher is discharging water, a lot of water floods out of the air gap. Why does this happen? Thank you! I love your Saturday AM show!


The air gap is just that – a gap of air in the dishwasher drain line so dirty water can not be forced up out of the sink and into the dishwasher.  When the gap leaks, it is normally due to a kink or blockage in the tube from the air gap to the tail piece (drain line) below the sink. The gap may need to be cleaned, or the drain line below the sink may be plugged.

Pull the cover off the air gap and check for debris blocking the opening. Check the line for kinks or blockage, and check the drain line itself.
