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.

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

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.
