Dishwasher Installation FAQs, answered by experts

Only if the dishwasher isn’t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

The average cost to repair a dishwasher that’s leaking is $200, but your total will depend on the underlying problem. Having a professional replace a faulty door gasket or a gasket in a supply line could cost as little as $50, while replacing a leaking dishwasher pump could total as much as $600.

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.

Some common signs you have a dirty dishwasher filter are:

Food sticking to your dishes even after a thorough wash cycle
Odor coming from your dishwasher
Stains left on dishes and utensils
Water pooling in your dishwasher
Food stuck to parts of the dishwasher, like the racks, walls, or sprayer arm
