A dishwasher with dishes in it, lasting 15 years.

Can a Dishwasher Last 15 Years?

Getting 15 years or more out of a dishwasher is possible, but depends largely on the quality of the appliance, how well you maintain it, and a bit of luck. With proper care and maintenance, many modern dishwashers can provide over a decade of reliable service.

Dishwasher Lifespan

The average lifespan of a dishwasher is around 9-12 years. However, high-end models from reputable brands that prioritize durability can last 15-20 years.

Factors That Affect Dishwasher Longevity

Several factors impact how long a dishwasher will last:

  • Brand quality – More expensive brands generally last longer than cheaper models. Look for renowned brands known for reliability.
  • Build materials – Diswashers made of stainless steel, high-grade plastics and quality parts tend to have greater longevity.
  • Usage frequency – Light to moderate usage helps a dishwasher last longer than heavy, constant use.
  • Water quality – Hard water can create mineral buildup and deposits inside the dishwasher, wearing it down more quickly.
  • Maintenance and care – Regular cleaning, part replacement, and avoiding leaks prevents premature breakdowns.

Tips to Extend Your Dishwasher’s Lifespan

With proper maintenance and care, you can maximize your dishwasher’s working life. Here are some tips:

  • Use a water softener if you have hard water issues. The minerals in hard water can damage the inner workings over time.
  • Clean and replace dishwasher filters regularly according to manufacturer instructions. Clogged filters make the motor work harder.
  • Use a dishwasher cleaner monthly to remove grease and limescale buildup. Vinegar can also dissolve deposits.
  • Immediately repair leaks. Water leakage around hoses and seals can cause internal rust and electrical issues.
  • Level the dishwasher properly to ensure water drains completely after each cycle. Standing water invites mold.
  • Don’t overload the dishwasher, which puts strain on the motor and heating elements.
  • Dry rubber gaskets and door seals regularly to prevent mold and cracking. Replace if worn out.

When to Consider Replacement

If your dishwasher is 15 years old, it may be time to start budgeting for a replacement:

  • Frequent breakdowns and high repair costs indicate the dishwasher is near the end of its lifespan.
  • Outdated or discontinued models often lack replacement parts. Limited support makes repairs difficult.
  • Significant changes in performance, such as dishes not getting cleaned properly, signal a failing dishwasher.
  • Strange noises coming from the pump or motor are a red flag something is wrong internally.

Consider purchasing an extended service plan or home warranty if your existing dishwasher warranty has expired. This can offset repair costs on an aging unit.

Overall, investing in a high-quality dishwasher and properly caring for it can help ensure it runs smoothly for 15 years or longer before a replacement is warranted. With regular maintenance, even budget models can provide over a decade of use.
