Dishwasher Installation FAQs, answered by experts

Maintenance includes regular filter cleaning, checking water connections, and ensuring that the unit operates at optimal efficiency without blockages.

Installation includes leveling the unit, connecting water and electrical lines, securing the unit, and testing for function and leaks.

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.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

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.
