What is the most common cause for a dishwasher not to drain?

• <div><p>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 <a href="https://www.angi.com/articles/how-to-unclog-dishwasher.htm">how to unclog a dishwasher,</a> but you may need to call in a plumber if you can’t locate and clear the clog yourself.</p></div>

Why does a dishwasher have to drain through the sink plumbing?

• <div><p>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.</p></div>

How long will it take to install my dishwasher?

• <div><p>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.</p></div>

• <div><p>No, you do not need a garbage disposal to have a dishwasher.
