Dishwasher Installation questions, answered by experts

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.

The frequency for cleaning your dishwasher filter depends on your usage habits. If you run the dishwasher daily and don't scrape or rinse dishes before loading, you should clean the filter about once a month. For those who use it only once or twice a week and rinse items beforehand, cleaning it every three to six months may be sufficient. A clear sign that your filter needs cleaning is a musty smell, even after a wash cycle. Regularly cleaning the filter is important to prevent food buildup and clogging over time. It can be helpful to add this maintenance task to your calendar to stay on schedule.

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.

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.

DIY installation or repair is possible with the right skills and tools, but if not done correctly, it can often lead to water leaks or improper connections.
