How long does a dishwasher last?

A dishwasher lasts about 9 to 12 years. Enter the install year and this calculator estimates the life left and flags when to start watching for a replacement, before a leak damages your cabinets or flooring.

Cleaning the filter, running a monthly cleaner cycle, and scraping instead of pre-rinsing all help. Once yours is past a decade, rusting racks, poor cleaning, and any pooling water underneath are signs it is time to shop.

These lifespans are typical ranges for a well-maintained unit. Hard water, heavy use, and skipped maintenance shorten them; regular service extends them. Use the estimate to plan a replacement fund, not as a firm expiration date.

Frequently asked questions

How long does a dishwasher last?
Dishwashers last about 9 to 12 years on average. Regular filter cleaning and cleaner cycles help; hard water and heavy daily use tend to shorten the life.
When should I replace my dishwasher?
Start budgeting once it is past about 9 years, especially if it no longer cleans well, the racks are rusting, or you see water pooling underneath, which signals a seal or pump on the way out.
