What is a Good Lifespan for a Dishwasher? Must Know

The average lifespan of a dishwasher is about 12 years, but it can vary depending on the brand, model, usage, and maintenance. Some dishwashers can last up to 20 years, while others may need to be replaced after 9 years or less. How can you tell if your dishwasher is nearing the end of its life, and what can you do to extend it? In this article, we will answer these questions and provide some tips on how to choose and care for your dishwasher.

Factors That Affect Dishwasher Lifespan

There are many factors that can influence how long a dishwasher lasts, such as:

  • Dishwasher quality: The quality of the materials, components, and design of the dishwasher can affect its durability and performance. Generally, higher-end dishwashers tend to last longer than cheaper ones, as they are made with more robust parts and have more advanced features. However, this is not always the case, as some brands may have better reputations and warranties than others.
  • Frequency of use: The more often you use your dishwasher, the more wear and tear it will experience. However, this does not mean that you should avoid using your dishwasher, as leaving it idle for too long can also cause problems, such as mold, rust, and leaks. The best practice is to use your dishwasher regularly, but not excessively, and to run full loads rather than partial ones.
  • Home water quality: The quality of the water that enters your dishwasher can also affect its lifespan. Hard water, which contains high levels of minerals such as calcium and magnesium, can cause scale buildup and clog the pipes, valves, and spray arms of your dishwasher. This can reduce the water pressure and the cleaning efficiency of your dishwasher, and eventually damage the heating element and the pump. To prevent this, you may need to install a water softener or use a dishwasher salt or additive to reduce the hardness of the water.
  • Maintenance and cleaning: Like any appliance, your dishwasher needs regular maintenance and cleaning to keep it in good shape. This includes checking and replacing the filters, gaskets, hoses, and other parts that may wear out or break over time. It also includes cleaning the interior and exterior of your dishwasher, removing any food debris, grease, or stains that may accumulate. You can use a dishwasher cleaner or vinegar to sanitize and deodorize your dishwasher, and run a self-cleaning cycle every few months.

How to Tell If Your Dishwasher Needs to Be Replaced

Sometimes, your dishwasher may show signs that it is nearing the end of its life, such as:

  • Poor cleaning performance: If your dishes are coming out dirty, spotted, or cloudy, it may indicate that your dishwasher is not cleaning properly. This could be due to a number of reasons, such as a clogged filter, a faulty spray arm, a low water temperature, or a lack of rinse aid. Some of these issues can be fixed by cleaning or replacing the parts, but if the problem persists, it may mean that your dishwasher is too old or damaged to function well.
  • Strange noises: If your dishwasher is making loud, unusual, or grinding noises, it may signal that something is wrong with the motor, the pump, or the bearings. These are some of the most expensive and complicated parts to repair or replace, and they may not be worth the cost if your dishwasher is already old or worn out.
  • Water leaks: If you notice water leaking from your dishwasher, it may indicate that there is a crack, a hole, or a loose connection in the tub, the door, the hose, or the valve. Water leaks can cause damage to your floor, your cabinets, and your electrical wiring, and they can also pose a safety hazard. You should fix the leak as soon as possible, or replace your dishwasher if the leak is too severe or frequent.
  • Rust or corrosion: If you see rust or corrosion on the exterior or the interior of your dishwasher, it may mean that your dishwasher is deteriorating and losing its integrity. Rust and corrosion can affect the appearance, the performance, and the safety of your dishwasher, and they can also contaminate your dishes. You should replace your dishwasher if the rust or corrosion is extensive or deep.

How to Extend Your Dishwasher Lifespan

There are some things you can do to extend your dishwasher lifespan, such as:

  • Choose a reputable brand and model: When buying a new dishwasher, you should do some research and compare different brands and models based on their quality, features, reviews, and warranties. Some of the brands that are known for their longevity and reliability are Miele, Bosch, KitchenAid, Whirlpool, and Samsung123. You should also look for models that have energy-efficient and water-saving features, as they can reduce your utility bills and your environmental impact.
  • Follow the user manual: The user manual of your dishwasher contains important information and instructions on how to use and care for your dishwasher. You should read it carefully and follow the guidelines on how to load, operate, and maintain your dishwasher. You should also avoid doing anything that may damage or void your warranty, such as using the wrong detergent, overloading the dishwasher, or tampering with the parts.
  • Use the right detergent and rinse aid: The detergent and rinse aid you use for your dishwasher can affect its cleaning performance and lifespan. You should use the type and amount of detergent and rinse aid that are recommended by your dishwasher manufacturer, and avoid using too much or too little. You should also avoid using regular dish soap, bleach, or vinegar, as they can damage your dishwasher and leave residues on your dishes.
  • Clean your dishwasher regularly: You should clean your dishwasher at least once a month, or more often if you use it frequently or have hard water. You should remove and clean the filter, the spray arms, and the door gasket, and check for any signs of wear or damage. You should also wipe down the interior and exterior of your dishwasher, and run a self-cleaning cycle with a dishwasher cleaner or vinegar. This will help prevent odors, stains, mold, and bacteria from building up in your dishwasher.
