Everything You Should Know: How Long Do Dishwashers Last?

A dishwasher is quite a selling feature in many homes and is also an easy appliance to install into your current kitchen, either a built-in or portable one. When buying a home with a dishwasher, it’s important to ask when it was installed to know how much longer you have before you may run into performance issues. If you’re looking to purchase a dishwasher for your current home, several factors can have some effect on its life.

  • Quality - Trusted brands will produce dishwashers that are more efficient, less noisy, and provide more features.
  • Price - While a higher price tag does not always mean higher quality, splurging on a dishwasher that is energy efficient or has desired features will be worth it for both long-term use and satisfaction.
  • Frequency of Use - On average, a dishwasher goes through five cycles a week. By reducing how often you use your dishwasher, you are more likely to have fewer repairs and can increase its life expectancy.
  • Maintenance - Neglect is the leading cause of shortening a dishwasher’s lifespan; routine maintenance will ensure you are getting the most mileage.

So, how long do dishwashers last? On average, a dishwasher’s life expectancy is 9 to 11 years. Keep reading to discover what you can do to make your dishwasher last longer!

How to Make Your Dishwasher Last Longer

  1. Practice proper dish etiquette. By controlling what you put in your dishwasher, you can increase its longevity. Before placing your dishes on the racks, ensure there is no food debris left on the surface. These large bits can clog the drainage hose, tear the filter, or damage the pump. You don’t want to overload your racks either. Inserting too many dishes can restrict the spray pattern and decrease the performance level of your dishwasher. Consequently, you may need a second cycle to ensure cleanliness, taking away from the dishwasher’s lifespan.
  2. Scrub the door seal. The seal between the dishwasher’s door and tub is prone to residue and food particle buildup. By scrubbing it with a rag and disinfectant (even white vinegar will do the trick) as needed, you can prevent odors, mold growth, and the seal from losing its stick. It’s best to avoid harsh chemicals, bleach-based disinfectants, and abrasive sponges when cleaning the dishwasher’s seal.
  3. Prevent rack rusting. Dishwasher racks are covered in a plastic coating to prevent the rusting of the metal below. However, over time, it may begin to chip. These small bits can cause a clot-like buildup in the pump, which can stop your dishwasher from working. To prevent this, at any indication of worn off plastic coating, add a layer of vinyl paint or replace the tine tips if necessary.
  4. Routinely clean the filter. A dishwasher’s filter collects all of those left-over food particles. However, you’ll need to manually clean the filter once a month or so to ensure your filter is working correctly and not leaving a gritty feeling behind. The filter should easily unscrew, allowing you to run it under water and gently wash with a soft sponge and warm soapy water. Avoid using brushes or steel wool, as they can damage the filter. This would also be the time to examine the filter for any larger holes. If found, installing a replacement filter would be required to avoid any significant damage to the other working parts of your dishwasher.
  5. Check out the spray nozzles. Sometimes, the spray nozzles can become obstructed with food debris. When this happens, use a toothpick or pipe cleaner to clean out the spray nozzle gently. However, be careful, as damaging a spray nozzle can affect the spray pattern and performance of the dishwasher.

While these are the best preventative measures to increase the lifespan of your dishwasher, machines do break, and time takes a toll. You may need to replace your dishwasher because it’s more cost-efficient than a repair, it is having performance issues, or it’s just time for an upgrade.
