Dishwasher Installation questions, 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.

To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior.

A dishwasher can help save you significant time when it comes to getting your dishes clean. It can also get your dishes more hygienically clean than washing by hand due to higher water temperatures and specialized detergents, effectively sanitizing them and reducing the risk of foodborne illnesses. Compared to hand-washing, a dishwasher typically uses less water and energy to clean the same amount of dishes, making it a more resource-efficient option.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

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.
