Most dishwashers last 10 to 15 years if you keep them in decent shape. But if yours is leaking, making weird noises, or leaving plates dirty, it’s probably time to face reality. You don’t need a degree in engineering to spot these issues—just a few minutes of observation. Here’s how to tell if your dishwasher’s still got gas left in the tank or if it’s time to call a pro.
If your dishwasher’s been acting up for months—like constantly leaking under the sink, running endlessly, or failing to clean dishes properly—it’s likely past its prime. Water spots, rust, or a strange burning smell? That’s not normal. Even if it still works, these problems often mean the internal parts are wearing out fast. If you’ve had to fix it three times in two years, it’s cheaper to replace than keep patching it up.
Want to stretch your dishwasher’s life? Start with the basics: clean the filter monthly (it’s usually at the bottom), check hoses for cracks, and use the right detergent. Hard water? Add a rinse aid to stop limescale buildup. Avoid overloading it—your dishes need space to get clean. And never run it with the door open; that’s a quick way to ruin the seal. These small habits add up. A well-maintained dishwasher can easily hit 12-15 years, saving you from unnecessary stress and costs.
When in doubt, ask a local repair expert. At Taunton Appliance Repair Solutions, we’ve seen dishwashers that lasted 18 years with regular care. But if yours is 10+ years old and struggling, replacement might be smarter than repair. Newer models are more efficient, quieter, and often cheaper to run long-term. Don’t wait until it floods your kitchen—act before the repair bill blows your budget. Your future self will thank you.
