Dishwashers typically last ten years but their lifespan can change based on how effectively they are operated. Assessing the door seal is a useful technique to determine whether your dishwasher requires maintenance.

In the dishwasher industry, Bosch is a famous and high-quality brand. They are not only much quieter than the typical dishwashers, but they also have NSF-certified washing operations. It can get rid of up to 99.09% of bacteria on the dishwasher’s exterior.

The dishwasher has top-notch load detectors, which direct users to the ideal allocation for effective dishwashing. Bosch dishwashers are one of the most popular brands on the market for other aspects as well.

It will be good to estimate a few more years of excellent cleaning when compared to the previous models when it relates to its longevity. Bosch dishwashers have a minimal longevity of 10 years when compared to the regular dishwasher’s average longevity.

What are the different factors that can affect the Lifespan of a Dishwasher?

factors that can affect the Lifespan of a Dishwasher

The Bosch dishwasher can probably last ten years in a normal home using it five times per week. If all requirements are met, this term could go up to 12 years. The lifespan of your Bosch dishwasher will rely on a variety of things.

Let’s examine several elements that affect a Bosch dishwasher’s lifespan and how they can be managed to achieve maximum effectiveness.

Frequency of Use and Detergent Quality

A dishwasher would last approximately ten years if it will be appropriately operated. Dishes could decrease the lifespan of the dishwasher if you left them in there overnight. Thus, dishwashers’ lifespans will be shortened if dirty plates are placed in them for a long. It will also affect the detergents to wash the dishes properly.

This is necessary to consider the quality of the detergent to let the dishwasher properly clean the plates. The dishwasher won’t remove the fat from the plates if you wash them with soap. The plates become encrusted with oil and making it impossible for the dishwasher to wash them. In this way, grease cannot be removed from plates with soap.

Work-load Per Cycle

The quantity of plates the dishwasher manages throughout each washing round can also shorten its lifespan over time. Besides the frequency with which you operate the dishwasher, the workload per cycle has also a major impact on the longevity of the dishwasher. 

A maximum load will cause the Bosch dishwasher to risk greater damage than a half-load or even a rinse-only mode. This is because longer and larger loads need more moving capacity and components.


Your Bosch dishwasher’s waste catcher is not the only part that requires maintenance. To ensure the components of the dishwasher run smoothly, it must be carefully maintained. Your supply of water will contain gunk formations if it is hard water, which allows the formation of bacteria as a result.

For this, you must employ a descale to prevent that. You can start the washing cycle at its maximum temperature for the first 30 minutes, then place the items in the dishwasher and let the process finish. You will have to repeat the process to remove the residual after you’re done.

You can use a moist towel or mild soap to cleanse the exterior doors and lock to avoid corrosion growth and grease accumulation. Then the Bosch Stainless Steel Conditioner can be used to maintain the dishwasher’s visual attractiveness.


A dishwasher is overloaded when it has too many dishes in it. If you are not cautious while using your dishwasher, this could cause injury to you as well as damage to the appliance.

When you load the washer or dryer with too many dishes, overloading might happen. Additionally, it may take place if you clean dishes manually. When washing dishes by hand, water spills can strike the floor and spread around the kitchen.

Cleanliness of the Filters

Although the dishwasher’s producers advise throwing away food remnants before washing plates, oils and debris can still find their way into the food filter. If the filter is not cleaned properly, it will fill with debris and stops letting water flow.

At the bottom of the lower rack is a mesh filter which you can access by lifting the rack. To open the filters, you can turn the sprayer arm out first and then anticlockwise.

Then you will have to take out the entire structure, which includes the mesh plate and the filter. To detach the filter, you will have to pull on the bottom of it.

After that, you will have to set the filter back together by replacing each element. Based on how you use the product, it is advised that you carry out the above-mentioned operation every three to six months. This is the first step in maximizing a Bosch dishwasher’s lifespan.

Quality of the Brand

The quality of the product is the last element that will impact how long your dishwasher will last. The dishwasher will not last very long if the components of the dishwasher are made by low-quality manufacturers and unreliable sources. But if you will prefer the good-quality items and components of the dishwasher, it will last a bit longer.

When should I replace my Bosch Dishwasher?

The clear indicators of a faulty system will require you to change your Bosch dishwasher when they become too visible. These indicators are given below:

  • When you see that your dishwasher can’t finish a washing process without quickly turning it off, there might be some issues. So, you will have to replace your dishwasher.
  • A dishwasher utilizes hot water to wash dirty dishes, which is a disaster for bacteria. If your plates don’t come out clean, there will be a clogged filter or a broken heat source. For this, you must think about changing your dishwasher.
  • You must think about how old your system is. Is it older than a Bosch dishwasher’s expected lifespan? This will help you decide whether or not you have to change your dishwasher.
  • Rust on the machine’s surface won’t reduce its effectiveness and performance. But if it happens internally, you need to find a replacement right away. This raises serious concerns about possible water leakage or contamination of your utensils.
  • While the door is not closing, it might be a sign of a broken door latch. The door will eventually deform from heat and pressure, making it difficult to close and turn on the machine.

Note: Most Dishwashers beep after intervals if there is a Door issue.
