Dishwasher Installation FAQs, answered by experts

How long it takes to remove a dishwasher depends on how quickly you can work and the positioning of the appliance. In most cases, you can expect to remove a dishwasher in one to two hours. If the connections are older, you’ll need to use a bit more elbow grease to loosen them. This can make the process a bit longer.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.

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.

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.

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
