Dishwasher Installation FAQs, answered by experts

Not all dishwashers are 60cm wide, but that tends to be the most common size. 60cm translates into roughly 24 inches, with most home dishwashers being between 22 and 24 inches wide. There aren’t metrics available but it’s been our experience that over 90% of household dishwashers in North America are around 24 inches wide by 24 inches tall.

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.

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.

Water may linger at the bottom of your dishwasher if the cycle is interrupted or if there’s a clog in the system. Begin by pressing and holding the cancel button to ensure the cycle finishes. You may need to check the filter, hose, air gap, and garbage disposal for clogs if it still doesn't drain. If the problem persists and there is no visible clog, a professional will need to assess and fix the problem for you.

A dishwasher filter should be replaced every five years, depending on the manufacturer's recommendations and the frequency of use. The exact timing can vary based on factors such as the hardness of your water, how well you rinse dishes before loading them, and how often you clean the filter. Regularly inspect the filter for signs of wear and tear or damage. If the filter appears worn out, damaged, or excessively clogged despite regular cleaning, it should be replaced sooner.
