Dishwasher Installation FAQs, answered by experts

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.

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.

It’s not worth fixing a 20-year-old dishwasher or any 20-year-old appliance. Twenty years is beyond the useful life span of nearly every major household appliance. Once the appliance nears the end of its useful life span, repairs will become more frequent. A replacement often becomes more cost-effective at that point.

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.
