Dishwasher Installation questions, 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.

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’ll need to manually remove the water with a plastic cup before removing the dishwasher.

Repairs typically cost between $150 and $600, depending on the issue, parts needed, and labor charges.

You can repair minor damage to a dishwasher drain hose with tape designed to handle moisture but it’s probably better to simply replace it. Dishwasher hoses are inexpensive items that, although they require some muscle to change, are best swapped out. You don’t want to find your kitchen has flooded because of a faulty part that usually costs between $10 and $30.

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.
