Dishwasher Installation FAQs, answered by experts

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.

No, you do not need a garbage disposal to have a dishwasher. A dishwasher will work without one, and while it's rare to see a home with a dishwasher that doesn't have a disposal, it is possible. The two appliances pair well and are often installed together because a disposal simplifies meal cleanup.

However, your dishwasher should not be used as a replacement for a garbage disposal. Subjecting it to continuous food leftovers can lead to major clogs. If you choose not to install a garbage disposal, you should thoroughly rinse your plates or scrape excess food into the trash or a compost pile before loading them into the dishwasher to prevent plumbing issues.

Descaling a dishwasher is important if you want to keep it working as efficiently and effectively as possible. Limescale builds up quickly in dishwashers that are used regularly, especially in areas with hard tap water. You need to descale your dishwasher regularly to ensure that your dishes come out clean.

Repairs typically cost between $150 and $600, depending on the issue, parts needed, and labor charges.

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.
