What is the typical life expectancy of a dishwasher?


Editorial team Published on

Most dishwashers last between 7 and 12 years, with an overall average of about 10 years.

According to data from Consumer Reports, about 21 percent of dishwashers break or lose performance within the first five years of ownership. How long your unit lasts depends heavily on build quality, usage, and routine care.

Lifespan by Brand Quality

  • Budget models: Last about 7 to 9 years.
  • Standard/Mid-tier brands (Whirlpool, GE, KitchenAid): Last 9 to 12 years.
  • Premium brands (Bosch, KitchenAid high-end): Last 10 to 15 years.
  • Luxury brands (Miele, Cove): Last 15 to 20 years.

Key Factors That Affect Lifespan

  • Usage frequency: Running the machine multiple times a day wears out motors and pumps faster than running it 3 to 4 times a week.
  • Water hardness: Hard water causes mineral scale buildup that clogs valves and damages heating elements unless you use a water softener or rinse aid.
  • Maintenance: Regularly cleaning the filter and clearing spray arms prevents the pump from overworking.
  • Tub material: Stainless steel tubs resist rust and retain heat better than plastic tubs, helping the machine last longer.

Signs It Is Time to Replace

  • Dishes stay dirty or cold after a cycle (indicating a heating element failure).
  • Water leaks or the door fails to close tightly.
  • Persistent bad odors or standing water at the bottom.
  • Repair costs exceed 50% of the price of a brand-new unit, especially if the machine is already over 8 to 10 years old.
