what causes dishwasher water to gush out of air vent
Dishwasher Venting Problems. Dishwasher venting problems are usually caused by a clogged vent or drain mechanism. As the dishwasher runs, water flows into the unit through the water supply and back out through the drain. To prevent the water from siphoning out of the unit during the washing cycle, air is vented from the dishwasher as water drains.
