What Is the Average Life Expectancy of a Dishwasher?

A top-grade modern dishwasher comes with a life expectancy of at least six years and at most up to 10-12 years. Thus, the average lifespan of a dishwasher is about nine years. 

How Long Does a Bosch Dishwasher Usually Last?

An average household that runs the Bosch dishwasher five times a week can easily utilize it for ten years. This period may even extend to 12 years if all of its prerequisites are satisfied. 

Let us look at some factors that influence the life expectancy of a Bosch dishwasher and how they can be dealt with to maximize efficiency.

Cleanliness of the Filter

While manufacturers always recommend discarding leftovers before putting plates in a washer, scrapes and grease can still make their way to the food filter. If not periodically cleaned, it clogs with residue and prevents water from passing. 

Upon removing the lower rack, you will find a mesh filter positioned at the bottom. Take out the spray arm first and then twist counterclockwise to open the filter. Now, pull out the whole structure consisting of the filter together with the mesh plate. Tug at the bottom of it to separate the filter. 

Look for large pieces of leftover food caught in the top and dispose of them. Then, take all three components and rinse them with warm, soapy water. Reach to all edges and insides of the filter to remove waste of all kinds. If any part is particularly grimy, let it soak in the mixture for a few hours. 

Put back all the components in place and reassemble the filter. It is recommended that you perform the said procedure every 3-6 months, depending upon your frequency of usage. This is the foremost step to maximize the life expectancy of a Bosch dishwasher.

Maintenance of the System 

The food trap is not the only component of your Bosch dishwasher that needs cleaning. Thorough maintenance of the entire assembly is essential for its smooth running. 

If your water supply consists of hard water, it may harbor limescale deposits that in turn promote bacteria growth. To avoid that, you must use a descaler (Bosch also has one for its products). Let the wash run at its highest temperature, add in the product after 30 minutes, and let the cycle continue. Once done, restart the cycle to clean off the residue. 

To prevent rust formation and grease build-up, clean the outer door and latch with a wet cloth or mild soap. After that, you may choose to apply the Bosch Stainless Steel Conditioner to sustain the aesthetic appeal of the dishwasher. 

The Right Load

To maximize the efficiency of any electrical appliance, first, you need to use it correctly. 

Load the Bosch dishwasher properly, letting each piece of cutlery have its own washing space. Start by placing utensils and smaller dishes in the upper rack. If your model comes with a cutlery drawer, that is where you should let bigger utensils rest.

Next, utilize the upper rack for fragile and light pieces. This area may even serve as a secure storage space for mugs and glasses. You can choose to adjust the height of the rack to accommodate taller pieces. The tines on the rack may hold bowls or unfold them to make more space for dishes. 

Make use of the bottom rack to place heavy crockery and accessories like pots and pans. 

Always load dishes at a good angle. For instance, spoons should always be business-end down and dishes facing downwardsRemember that the positioning of your utensils determines the flow of water and prevents situations of overload. 

Frequency of Use 

While there is no set standard for how frequently you may use the dishwasher, it still influences your system quality. As per reports, an average home runs at least five dishwasher cycles a week. 

Running less than five cycles would, by default, can boost the efficiency of the dishwasher. However, it would be futile if you are doing so with poor attention towards maintenance and repairs. 

On the contrary, running it more than five times can reduce the efficiency. Too much use can lead it to expire quicker. To prevent that, avoid running half-empty cycles, leaving the washer on after use, and being negligent in cleaning.

For instance, issues of the following kind call for quality repair processes, even if that involves hiring a professional. 

  • The water supply stops midway, or the washer poorly drains the water. In such a case, the problem is most likely a clogged filter only. 
  • The door may not latch properly and remain suspended, making you unable to wash dishes. A latch repair procedure by yourself or a professional could solve the problem. 
  • A dishwasher may produce weird and loud noises during wash cycles. In this case, either the fault lies in the motor or overloading the racks.

    • I’m wondering the same about mine – installed 2003. nothing is really real wrong except the 2 hour cycle is now 3.5 hours plus. (now, that i am paying attention). I think I will call tech support if they have that.

  1. My Bosch just died recently. It was only a few months shy of 18 years of use, sometimes with as many as 5 people living in the house. Well worth the money imo.

    • My Bosch dishwasher lasted only 3 years – very disappointing as it cost over £750. It was an integrated slimline that projected the time to run on the floor.

  2. My Bosch lasted 17+ years I just replaced it with another Bosch,100 series. My previous dishwasher lasted 17 years, and was still running when I upgraded. I think 6 – 10 years, as mentioned in this article is not at all correct.

  3. I am on 12 years with my Bosch dishwasher. Florida is notorious for its hard water reeking havoc on dishwashers and washing machines. Best dishwasher I’ve ever had. Only required repair one time as the rinse aid dispenser was leaking and it is still going strong.
