Dishwasher Installation questions, answered by experts

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

Dishwashers should be cleaned a minimum of once every 3 months, but really it should be done monthly. This is to prevent germ buildup and will help keep your machine running smoothly. Dishwasher maintenance isn’t too difficult, you’ll simply clean the filter, wipe down the spray arms with vinegar or rubbing alcohol, and run the cycle on empty. If there is any debris, you can remove it with a small metal pick. Do not use wood as the tip can break off inside the machine.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.
