Dishwashers typically last between 8 and 15 years, with an average lifespan around 10 to 12 years. The exact duration depends on factors such as brand, usage frequency, maintenance, and model quality.
- Average Lifespan: About 8-10 years is common, but many dishwashers can last up to 15 years or more with proper care
- Brand Differences: Some brands are known for longer durability. For example, Miele dishwashers can last up to 20 years, Fisher & Paykel about 15 years, Bosch and Siemens around 10-12 years
- Usage Impact: More frequent use shortens lifespan. For instance, increasing weekly cycles from 5 to 7 can reduce lifespan by about 20%
- Maintenance: Regular cleaning of spray arms, filters, and following manufacturer maintenance recommendations can extend life
- Signs for Replacement: Persistent issues like motor noise, poor water circulation, or dishes not cleaning/drying properly may indicate it's time to replace the dishwasher
In summary, with average use and good maintenance, expect a dishwasher to last roughly 10-12 years, but high-quality models and careful use can extend this to 15-20 years
