Strange noises. Frequent breakdowns. If your dishwasher isn’t running like it used to, you’re probably asking yourself: How long should a dishwasher last?

On average, most dishwashers last 9 to 12 years, but higher-quality models can run much longer with proper care. Understanding your dishwasher’s expected lifespan can help you avoid sinking money into repeated repairs and know when replacement is the smarter move.

Here, we’ll discuss the typical lifespan of a dishwasher, what affects its longevity, and the warning signs that it may be nearing the end. With insights from FOTILE, you can plan ahead, preserve your budget, and keep your kitchen running smoothly.

Factors That Affect Your Dishwasher’s Lifespan

Not all dishwashers wear out at the same pace. While the average dishwasher lifespan falls around a decade, several factors can shorten or extend how long yours lasts.

品牌

Build quality plays a major role in how long a dishwasher lasts. Premium brands use more durable motors, pumps, and stainless steel tubs, which can significantly extend lifespan compared to entry-level models.

品牌Estimated Lifespan
方太厨电 12-15 years
Miele15–20 years
Bosch 12-15 years
KitchenAid10–14 years
GE10–12 years
Whirlpool10–12 years
Frigidaire8–10 years

Frequency of Use

A dishwasher that runs once a day will wear out faster than one used a few times a week. More frequent cycles put more strain on the motor, pump, and spray arms.

Water Quality

Hard water can shorten your dishwasher’s lifespan by causing mineral buildup on internal components. Over time, this buildup can reduce efficiency, clog spray arms, and lead to early breakdowns.

安装

Faulty installation can lead to drainage issues, leaks, or electrical problems that shorten the life of your dishwasher. A proper installation helps the unit operate smoothly and reduces unnecessary stress on internal parts.

维护

Regular care can make a noticeable difference in your dishwasher’s lifespan. Simple habits like cleaning filters, checking spray arms, and using the right detergent can prevent buildup and keep components working as intended.

Is It Time to Replace Your Dishwasher? Common Signs

Knowing the warning signs of a broken dishwasher can help you decide when repairs no longer make sense:

  • Dishes come out dirty or cloudy, even after a full cycle
  • Frequent breakdowns or repeated service calls
  • Unusual grinding, rattling, or buzzing noises
  • Water leaks around the door or beneath the unit
  • Cycles take much longer than they used to
  • Rising energy or water bills with no other clear cause
  • Rust, cracks, or visible wear inside the tub

Should You Repair vs. Replace? How to Tell

Deciding whether to repair or replace your dishwasher comes down to cost, age, and how often problems recur. Here’s a clear comparison to help you weigh your options:

Repair May Make Sense When…Replacement Is the Better Choice When…
The dishwasher is under 8 years oldThe unit is 10+ years old
The repair cost is minorRepair costs are adding up
It has been reliable until recentlyBreakdowns happen frequently
Parts are easy to replaceReplacement parts are hard to find
Energy and water use are still reasonableEfficiency has noticeably declined

Many appliance professionals follow the “50% rule”: if a repair costs more than half the price of a new dishwasher, replacement is usually the smarter choice.

How to Expand Your Dishwasher’s Lifespan: Helpful Tips

A few simple habits can help your dishwasher run better and last longer.:

  • Clean the filter regularly to prevent food buildup
  • Rinse heavy food residue off dishes before loading
  • Use the right detergent and avoid overuse
  • Run hot water at the sink before starting a cycle
  • Avoid overloading, which strains the motor and spray arms
