Dishwasher Air Vent Leaking Water

A dishwasher air gap is a fitting mounted about two inches above the sink that prevents contaminated water from re entering the dishwasher from the drain via backflow.
Dishwasher air vent leaking water. There may be issues with the water inlet valve or water backflow. The gap where the water falls downward through the air instead of a hose functions to prevent siphoning and thus prevent backup into the dishwasher. An air gap is a simple way to make certain wastewater and contaminants never re enter your clean water supply. The main reason why you would have a leaking dishwasher vent is because the water pipes inside your dishwasher have become full of gunk.
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. A clogged or damaged air gap is one of the most common causes of problems people experience with their machine. The dishwasher leakage may be caused by a faulty water inlet valve which may be stuck open due to calcium builds ups.
In a properly functioning air gap the dishwasher hose attaches to an input on the air gap and the water is expelled out the end.

Air gap problems are usually caused by a leak or a clog in the drain hose. Pull the dishwasher drain line from the side of the garbage disposal and place.
The dishwasher refuses to push more water through the blocked pipe and therefore water has to escape through other exits such as the air vent pipe. A hard yet common problem is a dishwasher leaking when not running. The vent can be washed in soapy water to remove any grease and debris causing the blockage. Something that can be quite challenging to diagnose.
Air gaps prevent water from syphoning backward a possibility in the unlikely event the water level in the sink is high.
