Dishwasher Installation questions, answered by experts

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.  

Depending on your available time and skillset, there are some aspects of dishwasher repair you can DIY. Remember that dishwashers use water and electricity, which can cause potentially hazardous situations. However, there are some things you can do to reduce your overall repair cost, such as:

  • Cleaning the spray arm

  • Unclogging the float

  • Replacing the door gasket

  • Cleaning the door filter

  • Adjusting the door latch

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.

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.

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.
