Dishwasher Installation questions, answered by experts

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

Some signs that your dishwasher is going out include:

The door no longer latches
Dishes are still dirty after a cycle
Dishes are cold after a cycle
Rust inside or outside the unit
Cracks inside the dishwasher tub
Water collecting at the bottom or outside the unit

If your dishwasher is not energy-efficient or is older than 10 years, you should also consider replacing it. Repairing an older model may be more expensive than replacing it with something newer and more energy- or water-efficient.

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.

Some common signs you have a dirty dishwasher filter are:

Food sticking to your dishes even after a thorough wash cycle
Odor coming from your dishwasher
Stains left on dishes and utensils
Water pooling in your dishwasher
Food stuck to parts of the dishwasher, like the racks, walls, or sprayer arm

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.
