How long should a dishwasher last? About 10 years, according to most of the 20-plus manufacturers we asked. CR members tell us they expect the same life span, on average, but that doesn’t necessarily mean 10 trouble-free years.

How often should you replace your dishwasher?

Dishwasher. Dishwashers usually last between 10 to 15 years. They are very easy to repair and often times it’s a matter of one or two parts being out of place. This easiest way to tell if your dishwasher needs a repair is if your dishes aren’t getting clean.

Is it worth repairing a 10 year old dishwasher?

If it’s only a few years old and the repair cost is less than half of what a replacement would cost, you’re better off repairing it. If the repair cost is more than half of replacing it, or you’re at or past the 7- to 10-year mark, you’re better off replacing it with a new model.
