Dishwasher Lifespan Explained

If you're in the market for a new dishwasher, you may be wondering how long do dishwashers last. The lifespan of an average dishwasher can vary depending on several factors, but usually, you can expect a dishwasher to last around 9-12 years. Said factors that can affect the lifespan of your dishwasher are usage patterns, water quality, and the quality of the dishwasher itself. In this article, we will explore the various factors that can impact the lifespan of your dishwasher and provide tips on how to maximize its longevity and get the most out of your purchase and dishwasher installation cost. Let's take a closer look.

Factors Affecting Lifespan

The lifespan of your dishwasher can be affected by a multitude of factors. Some factors are related to the internal components of the dishwasher, while others are external and can be controlled by you.

Internal Factors

  • Quality of Parts: The quality of the parts used in your dishwasher can greatly affect its lifespan. Cheap or low-quality parts are more likely to fail and cause damage to other components.
  • Manufacturing Defects: Rare as they may be, manufacturing defects can cause your dishwasher to fail prematurely. These defects might not manifest until months or even years after purchase.
  • Dishwasher Brand: Not all brands are created equal. Some brands may use inferior parts or have a history of manufacturing defects, which can affect the lifespan of their dishwashers’ lifespan.

External Factors

  • Usage Frequency: The frequency at which you use your dishwasher can have a significant effect on its lifespan. The more you use it, the more wear and tear it will experience.
  • Usage Patterns: How you use your dishwasher can also affect its lifespan. Overloading your dishwasher or using the wrong detergent can cause issues that can lead to premature failure.
  • Maintenance: Regular maintenance is essential for maximizing your dishwasher's lifespan. Skipping routine maintenance tasks and not replacing dishwasher parts and accessories whenever needed can lead to problems that can cause your dishwasher to fail.
  • Water Quality: The quality of your water can also be a factor in your dishwasher's lifespan. Hard water can cause mineral buildup and other issues that can damage your dishwasher's components.

Taking these factors into consideration helps ensure that your dishwasher lasts as long as possible. While some factors are out of your control, many can be addressed through proper usage and maintenance.

Quality of Build and Durability

The quality of the build and durability of a dishwasher are some of the most critical factors that impact its lifespan. A well-built dishwasher with durable components is likely to outlast a poorly constructed one. When shopping for a dishwasher, it's crucial to consider the quality of the build and the materials used in its construction. One way to determine the quality of the build of a dishwasher is to assess its weight. A heavier dishwasher is indicative of a sturdier construction, which typically translates to a longer lifespan. Additionally, you can look for types of dishwashers that feature stainless steel components as they are more durable and long-lasting than plastic parts.

Another critical component to consider is the dishwasher's motor. A high-quality motor not only ensures efficient cleaning but also contributes to the dishwasher's longevity. A well-constructed motor is less likely to fail or break down, leading to a longer lifespan for your dishwasher.

It's also a good practice to read reviews and consult with experts before making a purchasing decision. This will help you get a better understanding of the build quality and durability of the dishwashers you are considering, be it built-in dishwashers or compact portable dishwashers.

To ensure the long-term durability of your dishwasher, it's essential to treat it with care and use it as recommended. Avoid overloading the dishwasher, using improper detergents, or washing items that are not dishwasher-safe. These practices can lead to damage and wear and tear, potentially shortening the lifespan of your dishwasher.

Usage Frequency and Patterns

The frequency and pattern of usage can have a significant impact on the lifespan of your dishwasher. Using your dishwasher too often or in an irregular pattern can cause undue stress on its components, reducing its longevity.

  • Frequency: It is recommended to use your dishwasher at least once a week to keep its components lubricated and prevent any buildup or rust. However, using it more than once a day or for smaller loads than recommended can increase wear and tear on the dishwasher.
  • Patterns: Another factor to consider is the pattern of usage. For optimal performance and lifespan, it is recommended to run your dishwasher at full capacity, avoiding frequent halfloads. Additionally, try to avoid overloading the dishwasher or stacking dishes too closely together, which can cause damage to the spray arms or other components.

By following these guidelines for usage frequency and patterns, you can help extend the lifespan of your dishwasher and save on costly dishwasher repair or having to get a newer dishwasher replacements in the future.

Maintenance Tips for Your Dishwasher

If you want to extend the lifespan of your dishwasher, proper maintenance is key. Here are some essential tips to keep it running smoothly and efficiently:

  • Clean the interior regularly: Wipe down the interior of your dishwasher with a damp cloth after each use to prevent food particles and debris from building up. Use a mild detergent or vinegar solution for a deeper clean.
  • Remove and clean the filter: Most dishwashers have a filter that traps food particles and other debris. It's important to remove and clean it regularly to keep it from clogging and impacting the machine's performance. Consult your owner's manual for instructions on how to remove and clean the filter.
  • Check the spray arms: The spray arms distribute water during the wash cycle. Over time, they can become clogged with debris or mineral deposits. Make sure to check them regularly and clean out any obstructions with the help of some dishwasher cleaner.
  • Inspect the dishwasher door gasket: The door gasket creates a door seal to that keeps water from leaking out of the dishwasher. If it becomes worn or damaged, it can lead to leaks. Check it regularly and replace it if necessary.
  • Run hot water before starting a cycle: To ensure that your dishwasher is using hot water from the start of the cycle, run the hot water in your sink for a few minutes before starting the dishwasher.
  • Avoid overloading: Overloading your dishwasher can put a strain on the motor and other components. Make sure to load it properly and avoid overcrowding.

By following these maintenance tips, you can ensure that your dishwasher stays in good condition and maximizes its lifespan. Remember, regular care and attention can save you money in the long run!

Water Quality and Hardness

Your dishwasher’s lifespan can be negatively impacted by the quality of the water it uses. Hard water, which contains high levels of mineral deposits, can cause buildup and clogging in your dishwasher’s internal components. Over time, this can lead to reduced performance and even total breakdown of the dishwasher.

One effective solution is to use a water softener, which can remove harmful minerals from the water before it enters your dishwasher. Another option is to use a cleaning solution specifically designed to remove mineral buildup from your dishwasher’s internal components. It’s important to regularly check your dishwasher’s filter and clean it as needed. This can prevent mineral buildup in the dishwasher and keep it functioning efficiently. It’s recommended to clean the dishwasher filter at least once a month, or more frequently if you have particularly hard water. Finally, if you’re unsure about the water quality in your area, you can have it tested. This can help you determine if a water softener or other solution is necessary to protect your dishwasher and prolong its lifespan. 

Now that you have a better understanding of the lifespan of dishwashers and the factors that can affect them, you can take steps to extend the longevity of your appliance. Remember to consider the quality of build and durability of your dishwasher when making your purchase from the vast array of high-quality dishwashers or dishwasher drawers at Town Appliance, and be mindful of your usage frequency and patterns. Regular maintenance such as cleaning and filter maintenance can also go a long way in keeping your dishwasher running efficiently. It's also important to keep an eye on the water quality and hardness in your area, as hard water can cause mineral buildup and other issues that can shorten the lifespan of your dishwasher.
