Dishwasher Installation FAQs, answered by experts

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.

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.

Maintenance includes regular filter cleaning, checking water connections, and ensuring that the unit operates at optimal efficiency without blockages.

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.

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.
