Dishwasher Installation FAQs, answered by experts

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.  

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

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.

Costs depend on labor rates, replacement part prices, brand, and whether emergency service is required.

You can repair minor damage to a dishwasher drain hose with tape designed to handle moisture but it’s probably better to simply replace it. Dishwasher hoses are inexpensive items that, although they require some muscle to change, are best swapped out. You don’t want to find your kitchen has flooded because of a faulty part that usually costs between $10 and $30.
