How long does a dishwasher last?
You can expect a dishwasher to last about 8 to 15 years, with an average of 11 years. Like any appliance, heavy usage will shorten it life and only occasional usage will lengthen it—except a dishwasher that is unused for a long period will cause the rubber doors seals to deteriorate, crack, and leak.
Also, see our other blog posts How far away from the sink can I install a dishwasher? and Does a home inspector check the dishwasher? and When was GFCI-protection for kitchen dishwasher receptacle outlet first required? and Can a dishwasher be wired to a kitchen counter small appliance receptacle circuit? and Can a dishwasher drain hose be connected after the sink trap (to the trap arm)? and What is a "high drain loop" or "air gap" in a dishwasher drain hose?
Here’s a graph comparing the life expectancy of a dishwasher to other major home appliances.
