Dishwasher Installation questions, answered by experts

To get rid of standing water in your dishwasher, first try activating the drain mechanism by pressing and holding the cancel button for at least three seconds. If that doesn’t work, you’ll need to do some troubleshooting to drain the standing water from the dishwasher. This will involve shutting off the power, then scooping out the water, cleaning the drain filter, and clearing the air gap. You’ll also want to run the garbage disposal and check the drain hose for clogs.

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

Some signs that your dishwasher is going out include:

  • The door no longer latches 

  • Dishes are still dirty after a cycle 

  • Dishes are cold after a cycle 

  • Rust inside or outside the unit 

  • Cracks inside the dishwasher tub

  • Water collecting at the bottom or outside the unit

If your dishwasher is not energy-efficient or is older than 10 years, you should also consider replacing it. Repairing an older model may be more expensive than replacing it with something newer and more energy- or water-efficient.

DIY installation or repair is possible with the right skills and tools, but if not done correctly, it can often lead to water leaks or improper connections.

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.
