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>

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.

Q: Why is there still water in the bottom of my dishwasher?

• <div><p>Water may linger at the bottom of your dishwasher if the cycle is interrupted or if there&rsquo;s a clog in the system. Begin by pressing and holding the cancel button to ensure the cycle finishes. You may need to check the filter, hose, air gap, and garbage disposal for clogs if it still doesn't drain. If the problem persists and there is no visible clog, a professional will need to assess and fix the problem for you.</p></div>

Q: Do you need a garbage disposal for a dishwasher?

• <div><p>No, you do not need a garbage disposal to have a dishwasher. A dishwasher will work without one, and while it's rare to see a home with a dishwasher that doesn't have a disposal, it is possible. The two appliances pair well and are often installed together because a disposal simplifies meal cleanup.</p><p>However, your dishwasher should not be used as a replacement for a garbage disposal. Subjecting it to continuous food leftovers can lead to major clogs. If you choose not to install a garbage disposal, you should thoroughly rinse your plates or scrape excess food into the trash or a compost pile before loading them into the dishwasher to prevent plumbing issues.</p></div>

Q: Do you need to drain a dishwasher before moving it?

• <div><p>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&rsquo;ll need to manually remove the water with a plastic cup before removing the dishwasher. </p></div>
