Dishwasher Installation questions, answered by experts

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.

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.

A standard dishwasher size is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes.

If the dishwasher is in working condition, start and run a complete cycle with nothing inside. Let it drain and sit overnight before removing the hoses. In theory, it should effectively drain. You may find residual water in the hoses, but you can plug them. If the dishwasher breaks down midcycle it can sometimes be full of water. You’ll need to manually remove the water with a plastic cup before removing the dishwasher.

Your first instinct might be to grab the bleach to clean a moldy dishwasher, but it’s not the best product for the job. You don’t want to use bleach to clean stainless steel components if your dishwasher has them, as it can cause significant damage. In addition, the scent of bleach can linger if not rinsed well, causing your dishes to retain a smell (and even taste) of bleach.
