Dishwasher Installation questions, answered by experts

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. 

A dishwasher filter should be replaced every five years, depending on the manufacturer's recommendations and the frequency of use. The exact timing can vary based on factors such as the hardness of your water, how well you rinse dishes before loading them, and how often you clean the filter. Regularly inspect the filter for signs of wear and tear or damage. If the filter appears worn out, damaged, or excessively clogged despite regular cleaning, it should be replaced sooner.

It might be time to buy a new dishwasher for your kitchen if you consistently notice a significant amount of water left over after a cycle, indicating potential drainage issues that are becoming persistent or costly to fix. Visible rust, especially on the interior tub or racks, suggests internal corrosion that will likely worsen over time and can compromise cleaning performance. Additionally, if your dishes are coming out excessively hot after the drying cycle, it could point to a malfunctioning heating element or thermostat, which can be an energy inefficiency and a potential safety concern, making replacement a feasible choice.

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.

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.
