Shop DishwashersWhat is the Average Lifespan of a Dishwasher?
Here’s the deal: The average lifespan of dishwashers is around 10 years. However, quality dishwashers will last longer. Currently, the longest lasting dishwasher, produced by Miele, is designed to keep running for 20 years. Understanding how long should a dishwasher last depends on the type of dishwasher. Here are a few pointers to keep in mind.
How Long Do Built-In Dishwashers Last?
The longevity of a built-in dishwasher depends on the brand, usage, and specific model. Typically, stainless steel dishwasher tubs, dishwasher racks made with quality materials, and advanced dishwasher motors all contribute to a longer lifespan on built-in dishwashing machines.
How Long Do Portable Dishwashers Last?
Portable dishwashers also last around 10 years. However, they are more prone to wear and tear between moving the appliance between uses, and since these models are usually made with more affordable materials like plastic dishwasher tubs.
How Long Do Drawer Dishwashers Last?
Drawer dishwashers are often produced by luxury brands that cater to high-end customers. As a result, they’re usually made with better materials, which help them last 10 years or more. Just keep in mind: Drawer dishwashers have more parts than standard dishwashing machines, which makes them prone to more damage and repairs.
Factors That Affect a Dishwasher’s Lifespan
Understanding which dishwashers last the longest is only part of the equation when you are shopping for a dishwasher. You also need to embrace healthy habits that support the longevity of your appliance. Here are seven different factors that affect how long a dishwasher lasts.
Dishwasher Tub
If you are ready to invest in a quality dishwasher, make sure it has a stainless-steel tub. These tubs are more durable, ensuring they last longer while delivering better performance overall. While more affordable, plastic dishwasher tubs are more likely to stain or take on orders in the long run. Stainless tubs also retain heat better, so your dryer doesn’t have to work as hard, preventing it from wearing out.
Featured Pick: Bosch® 300 Series 24" Stainless Steel Front Control Built-In Dishwasher
This Bosch dishwasher is a perfect example of an appliance with a stainless steel tub. The PrecisionWash® system uses sensors to identify the soil levels of your dishes. This way it doesn’t waste water or energy, while also reducing wear on the appliance itself. Best of all, each Bosch dishwasher completes 485 quality checks, so durability comes standard.
Dishwasher Motor
When asking, “How long should a dishwasher last", you need to think about all of the parts that could break. A worn-out motor won’t run as efficiently, driving up your costs while potentially leaving your dishes dirty. Look for brands that invest in their dishwasher motor technology such as inverter drive motors or other specialty dishwasher motors with fewer parts that are less likely to break down.
Featured Pick: LG 24" Stainless Steel Look Front Control Built-In Dishwasher

“It is easy to operate, load, unload, and maintain. I like the space on the bottom, specifically the removable silverware basket instead of having to take the utensils out individually.”
Dishwasher Materials
The stainless steel vs. plastic tub debate highlights how different materials can affect the average lifespan of a dishwasher. Look materials that don’t rust but don’t wear out easily, and it can be hard to strike that balance. Commonly used parts that are often overlooked include dishwasher racks, spray arms, and tub material, so be sure to check whether these parts are made of quality materials. Here’s a good example!
Featured Pick: Monogram Statement 24" Stainless Steel Built-In Dishwasher
This Monogram dishwasher uses marine-grade bearings for its racks to provide more durability, along with other top materials. Monogram also includes LED lights, allowing users to check on your dishes even during the night. Every aspect of this dishwasher feels high-end, from the quality racks to the stainless steel construction and its ultra-quiet 39-dBA dishwasher noise rating.
Dishwasher Brand
Answering “How long should a dishwasher last” also depends on the brand you choose. A top-rated dishwasher brand will always outlast a bargain brand because it is made with higher-quality materials and better technology.
Here are a few top brands to consider:
- Bosch Dishwashers: This brand builds 485 quality checks into its dishwashers and produces some of the quietest dishwashers on the market.
- Miele Dishwashers: This is another quality German brand that is known for its attention to detail. Miele dishwashing machines are of the highest grade with lifespans of 20 years.
- KitchenAid Dishwashers: This premium appliance brand is known for balancing advanced technology with durability. KitchenAid dishwashers are known for their roomy interiors, quiet operation, and cutting-edge feature.
- GE Dishwashers: This is one of the most trusted brands in America. GE offers a variety of affordable yet reliable dishwashers from its core series, as well as upgrades from the GE Profile dishwasher, Cafe, and Monogram sister lines.
- Whirlpool Dishwashers: Buyers looking for affordable dishwashers will have plenty of options to explore from this lineup. While entry-level models aren’t as durable, mid-end Whirlpool washing machines up the ante with durable models that don’t break the bank.
Featured Pick: Miele 24" Built-in Dishwasher
Miele is the longest-lasting dishwasher brand on the market with a 20-year average lifespan. If you are looking to invest in a quality dishwasher that lasts, choose Miele. Aside from its quality construction, this model features a door automatically that opens at the end of the cycle, allowing any remaining moisture to air dry. Premium dish baskets and racks, plus a durable dishwasher tub, combine for a high-end dishwasher experience unlike any other.
Hard Water
Hard water can cause mineral buildup in your dishwasher, potentially making the jets less powerful and the drain less efficient, ultimately reducing a dishwasher’s lifespan. You may notice hard water buildup in your dishwasher if you see a white film or crust forming within the drum. While mostly limited to premium models, consumers have the option of a dishwasher with a built-in water softener, which increases lifespan while improving dish results.
Featured Pick: Cove® 24" Panel Ready Built-In Dishwasher
This dishwasher model by Cover includes a water softener feature, which combats hard water and its wear and tear. You don’t always get to control the quality of your water, but you can soften it for your dishes. This is also a smart appliance that lets you manage your dishwasher remotely. With extensive testing, Cove dishwashers are made to last 20 years, rivaling even Miele models.
Wash Frequency
It’s simple: Dishwashers that are used more often will wear out faster. In fact, most dishwashers are designed to run five times per week, and running them at least once a week can keep everything in working order. However, running multiple loads a day (or more than five loads weekly) will affect how long a model runs.
So, how do users avoid more loads than necessary? A roomy dishwasher is the best defense, so focus on dishwasher place settings, as well as loading features such as third racks, adjustable dishwasher trays, and fold-down tines.
Featured Pick: GE Profile™ 24" Fingerprint Resistant Stainless Steel Top Control Built-In Dishwasher
Shop This GE Profile Dishwasher
This dishwasher by GE Profile has 16 place settings to keep up with busy families. It is also an Energy Star-certified dishwasher, reducing the amount of water and electricity used, so even if you have to run more loads, you’re not hogging energy. A removable silverware caddy is a lovely perk that allows users to create even more room for bulky dishes, eliminating the need to run an extra load.
How You Load Dishes
Even your loading habits can affect how long a dishwasher lasts. That’s because overloading your dishwasher can cause obstructions and prevent it from completely cleaning your cookware. Placing heavier pots where lighter dishes are supposed to go can potentially bend or break the tines. As mentioned above, special dishwasher racks and loading features are the key to eliminating issues.
Featured Pick: KitchenAid® 24" PrintShield™ Stainless Steel Built-In Dishwasher
Shop This KitchenAid Dishwasher
If you need a large-capacity dishwasher, look for an appliance that maximizes loading flexibility.

Signs Your Dishwasher is Dying
Your dishwasher will let you know when it is wearing out. While you can always invest in dishwasher repairs, it might be better in the long run to replace your aging appliance. A few signs that it’s time to replace your dishwasher include:
❗Dishwasher Noise: Take note if your dishwasher is getting louder or making new noises. In many cases, it may be a dish or silverware obstructing the spray arm, but if the noise is loud and continuous, it may be a tell-tale sign of bigger problems.
❗Dishwasher Leaves Dishes Dirty: If you haven’t changed any of your loading habits, dirty dishes are a sign that your dishwasher isn’t working properly.
❗Dishwasher Odor: Smells that linger or worsen are bad signs for dishwashers. Start by cleaning the dishwasher filter. If that doesn’t work, check the hose for clogged food debris. If none of these work, the odors could be from accumulated grime trapped in the tub.
❗Dishwasher Leaking: A leaky dishwasher could be a serious issue that could damage your floors and even your foundation. Address leaks immediately by checking the hose, followed by the water inlet valve.
Ask the Pros | How to Keep Your Dishwasher Running
Even the most durable dishwashers need care to keep running at their best. Here are a few dishwasher maintenance habits to adopt.
✅Clean the dishwasher filter often. This will prevent debris from building up and reduce odors.
✅Check the spray arms regularly. Look for blockages, hard water buildup, and debris.
Perform routine dishwasher sanitizations. Running the dishwasher on empty with a bowl of vinegar can prevent the buildup of mold and mildew.
✅Don’t overload your dishwasher. This will ensure your dishes are cleaned correctly while preventing damage.
✅Use the right amount of detergent. This will prevent detergent from getting left behind and potentially clogging your drains.
Most of these dishwasher care tips only take a few minutes each day but can have a big impact on your appliance. You can enjoy better cleaning results and a dishwasher that lasts longer than you expect.
