Quick Answer
Use the age and fault-type test to decide: repair a dishwasher under eight years old with a single-component fault, and consider replacement once it passes ten years old or has multiple faults occurring at the same time.
A dishwasher's repair history matters as much as its age — a machine with several past repairs is a different consideration to one that's never needed attention.
A broken dishwasher doesn't automatically mean it's time to buy new. Here's the decision framework that removes the guesswork.
The Age Test
- Under 5 years: repair almost always makes sense
- 5–8 years: repair for most single-component faults
- 8–10 years: repair if the fault is minor and isolated
- Over 10 years: replacement worth considering for major faults
The Fault-Type Test
A blocked filter, worn seal, or faulty water inlet valve are low-complexity repairs worth doing on almost any dishwasher. A failed control board or major internal leak is where age becomes the deciding factor.
Brand-Specific Considerations
Premium brands generally have better long-term parts availability, which tips the decision toward repair even at a higher age. Entry-level brands with a shorter typical lifespan are worth weighing more carefully once a major fault appears.
