Dishwasher Installation FAQs, answered by experts

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.

Your first instinct might be to grab the bleach to clean a moldy dishwasher, but it’s not the best product for the job. You don’t want to use bleach to clean stainless steel components if your dishwasher has them, as it can cause significant damage. In addition, the scent of bleach can linger if not rinsed well, causing your dishes to retain a smell (and even taste) of bleach.

While the exact appearance of the filter will depend on your dishwasher brand, it often consists of a cylindrical or rectangular mesh or plastic component. The filter is located at the bottom of the dishwasher beneath the lower spray arm. It includes a combination of a coarse filter, which traps larger food particles, and a finer filter, which captures smaller debris. The filter assembly may be a single unit or a multi-part system that can be twisted or snapped out for cleaning.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.

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.
