Dishwasher Installation questions, answered by experts

If the dishwasher is in working condition, start and run a complete cycle with nothing inside. Let it drain and sit overnight before removing the hoses. In theory, it should effectively drain. You may find residual water in the hoses, but you can plug them. If the dishwasher breaks down midcycle it can sometimes be full of water. You’ll need to manually remove the water with a plastic cup before removing the dishwasher.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.

Your dishwasher drains through a hose that attaches to the plumbing below your sink or snakes out the back of your machine. In most cases, you can access one side of the hose from below your sink, as it usually ties into the same drainline that your sink uses. Otherwise, you may need to pull the dishwasher out of the counter to access it.

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.  

Basic maintenance, such as cleaning filters, is DIY-friendly, but repairs involving electrical components, pumps, or valves should be handled by a professional.
