What is the average lifespan of a dishwasher?

The average lifespan for a dishwasher is nine years. Proper maintenance, such as cleaning the filter and completing minor repairs, helps the appliance last as long as possible. In addition, the more special features a dishwasher has, the more components there are to develop problems.

Small mends of door latches, drain pumps, fill valves, door seals, soap dispensers and pressure switches are relatively inexpensive. However, there are some disruptions that signal that it is time for a new machine. A circulation pump or motor that is no long under warranty typically costs over $400 to fix, so the expense should be weighed against the cost of a buying a new dishwasher altogether.
