How Long Do Dishwashers Last? Top Tips for Maintaining Your Dishwashers and Extending Their Lifespan

Dishwashers are indispensable appliances in modern kitchens, providing convenience and saving time for homeowners. They offer a reliable way to clean dishes, cutlery, and other kitchenware. Consumer Reports offers valuable insights to help you choose the best model based on performance, reliability, and overall value when looking for a new dishwasher.

Like any appliance, dishwashers have a lifespan, and understanding how long they last and how to extend their life expectancy can help you get the most out of your investment. This post will explore the factors influencing a dishwasher’s longevity and provide practical maintenance tips to keep it running efficiently for years.

Understanding Dishwasher Lifespan

The average lifespan of a dishwasher is about ten years, but many factors can affect this life span. Usage, maintenance, and even the appliance’s brand can influence how long your dishwasher lasts. For instance, some brands, such as Bosch and KitchenAid, are known for producing durable and reliable dishwashers that can last longer than others. On the other hand, heavy usage, improper care, and lack of maintenance can decrease your dishwasher’s lifespan.

The Impact of Usage on Lifespan

One of the most significant factors affecting the life expectancy of your dishwasher is its usage. If you frequently run cycles with large loads, you may put more strain on the machine’s components, potentially leading to premature wear. Similarly, using your dishwasher to clean heavily soiled items or dishes with food residue may wear out faster.

Maintenance Matters

Regular maintenance is key to extending the lifespan of any appliance, including dishwashers. Performing routine checks and cleaning tasks can help maintain your dishwasher’s cleaning power and prevent the buildup of grease, debris, and mineral deposits that could damage the machine. Proper care will help you avoid costly repairs and improve the appliance’s efficiency, ensuring that your dishes come out sparkling every time.

Brand and Model Considerations

Different dishwasher brands have varying levels of reliability. Brands such as Bosch, KitchenAid, and Whirlpool are known for manufacturing high-quality machines that offer great longevity. Investing in a reputable brand makes you more likely to enjoy a longer lifespan. However, even the most durable models require maintenance to ensure they continue to function efficiently.

Easy Maintenance Tips for a Longer-Lasting Dishwasher

Proper care and easy maintenance tips can go a long way in extending the life of your dishwasher. Here are a few essential tips to keep your machine running smoothly:

Scrape Plates, But Don’t Rinse

Before placing dishes in the dishwasher, scrape off any large food particles. Avoid rinsing the dishes too thoroughly, as this could clog the spray arms, filters, or pumps. The dishwasher’s cleaning cycle is designed to handle minor food residue, so scraping is enough to prevent clogs without damaging the machine.

Clean the Filter Regularly

A clogged or dirty filter can reduce your dishwasher’s efficiency, causing dishes to come out with residue or gritty spots. Clean the filter at least once a month, or more frequently if needed. This simple task ensures that your dishwasher operates at peak performance, improving the cleaning power and overall efficiency.

Remove Hard Water Deposits

Hard water can leave mineral deposits on your dishwasher’s components, impairing performance over time. To prevent this, use a citric-acid-based dishwasher cleaner like Affresh or Finish to remove mineral buildup and keep the machine running smoothly. This cleaning solution helps to eliminate mineral films, restoring your dishwasher’s cleaning ability.

Inspect Spray Arms for Blockages

Over time, food debris and hard water buildup can clog the holes in your dishwasher’s spray arms. Check the spray arms every few months to ensure they are free from obstructions. If you notice any blockages, use a toothpick or soft brush to clear them. This will allow the water to flow freely, allowing the dishwasher to clean your dishes effectively.

Rustproof the Racks

Dishwasher racks can corrode over time, especially if the protective plastic coating wears off. Rusty racks can result in rust particles contaminating your dishes or clogging the pump. If you notice any signs of corrosion, consider replacing or repairing the racks by re-coating the rusted areas to prevent further damage.

Cleaning and Maintenance Routine

Running a regular cleaning and maintenance routine is essential for maintaining the efficiency of your dishwasher. Here’s how to keep your dishwasher in top condition:

Use White Vinegar for a Deep Clean

To remove any grease or buildup inside the machine, run a full cycle at the highest temperature setting while placing a cup of white vinegar on the top rack. The vinegar will help disinfect and clean the interior, ensuring that your dishwasher continues functioning at its best.

Regularly Clean the Door and Filter

The dishwasher door and filter are crucial parts of your appliance’s operation. Ensure to clean the door seal regularly, as food residue can accumulate and cause leaks. Clean the filter frequently to prevent debris buildup that could affect the draining process and decrease the dishwasher’s efficiency.

Run Hot Water for Optimal Performance

Hot water not only sanitizes dishes but also helps maintain the dishwasher’s parts. The high temperature ensures that grease and food residue are broken down effectively. While you should avoid running your dishwasher with extremely hot water for energy-saving purposes, occasionally, using a high-temperature cycle will help keep everything clean and functioning properly.

Dishwasher Door and Filter Maintenance

The dishwasher door and filter require special attention for optimal performance. Here’s how to maintain them:

Check the Door Seal for Leaks

Inspect the door seal for wear and tear, as damaged seals can cause water leaks. A leaking dishwasher may damage your kitchen and decrease the appliance’s efficiency. Replace any worn seals promptly to prevent this issue.

Regular Filter Cleaning

The filter catches food particles and debris but can become clogged over time. Clean the filter regularly to maintain efficient drainage and water flow. A clogged filter can prevent your dishwasher from cleaning effectively, accumulating grease and grime inside.

Proper Loading and Unloading

Properly loading and unloading your dishwasher can significantly impact its performance and longevity. Follow these tips for optimal loading:

Avoid Overloading the Dishwasher

Overloading the dishwasher can restrict water spray patterns, resulting in improperly washed dishes. Overloading can also put unnecessary strain on the machine’s pump and motor, reducing its lifespan and loading the dishwasher according to the manufacturer’s guidelines to avoid these issues.

Scrape Large Food Particles

Before loading your dishes into the dishwasher, scrape off large food particles. This helps prevent food from clogging the filter or spray arms and ensures the dishwasher can clean your dishes efficiently.

Water and Detergent Management

Proper water and detergent management is essential for maintaining a dishwasher’s efficiency and longevity. Here are a few tips:

Use the Right Detergent

Using the right amount of detergent is important to avoid residue buildup on your dishes and the dishwasher. Excess detergent can cause a soapy residue inside the machine, damaging components over time.

Regeneration Salt for Hard Water

Hard water can cause mineral buildup inside the dishwasher, affecting its performance. Regeneration salt can help prevent clouding on your dishes and maintain the dishwasher’s efficiency in hard water areas.

Troubleshooting and Repair

If your dishwasher is experiencing issues, it’s crucial to address them promptly. Sometimes, repairing a dishwasher is more cost-effective than replacing it entirely.

Know When to Repair or Replace

If your dishwasher isn’t cleaning or drying your dishes properly, or it’s making strange noises, it might be time to inspect it. If the appliance is still relatively new and only needs minor repairs, it’s worth fixing. However, if the machine is old and the repairs are costly, you may consider replacing it with a new model.

Regular Checks for a Healthy Dishwasher

Scheduling regular maintenance checks is an effective way to prolong the life of your dishwasher. A professional can inspect the appliance, clean components, and ensure everything functions correctly.
