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.

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 standard dishwasher size is 24-by-24-by-35-inch for a built-in unit. The depth and height line up perfectly with most kitchen countertops and cabinet sizes.

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. 

The only way to repair a dishwasher door hinge is to replace the broken or damaged hinge. To do this, you'll want to remove the old hinge, install a new one that fits your specific dishwasher model, and reattach the panel.
