Dishwasher Installation questions, answered by experts

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.

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.

Water may linger at the bottom of your dishwasher if the cycle is interrupted or if there’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.

The cost to repair a dishwasher depends on the type and scope of the problem. Replacing a heating element typically costs between $150 and $250 , for example. Depending on the age of your dishwasher and the extent of the problem, replacing the machine may be the more cost-effective option.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.
