Dishwasher Installation questions, answered by experts

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

The average cost to repair a dishwasher that’s leaking is $200, but your total will depend on the underlying problem. Having a professional replace a faulty door gasket or a gasket in a supply line could cost as little as $50, while replacing a leaking dishwasher pump could total as much as $600.

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. 

Your dishwasher drains through a hose that attaches to the plumbing below your sink or snakes out the back of your machine. In most cases, you can access one side of the hose from below your sink, as it usually ties into the same drainline that your sink uses. Otherwise, you may need to pull the dishwasher out of the counter to access it.

To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it’s necessary to install an air gap device to meet the code.
