Dishwasher Installation questions, answered by experts

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

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.

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

Your dishwasher drains through a hose that attaches to the plumbing below your sink or snakes out the back of your machine. In most cases, you can access one side of the hose from below your sink, as it usually ties into the same drainline that your sink uses. Otherwise, you may need to pull the dishwasher out of the counter to access it.

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
