Dishwasher 48

Understanding the type of salt to use in your Bosch dishwasher and why it’s necessary can make a significant difference in the performance and longevity of your appliance. This comprehensive guide will provide you with all the information you need regarding the importance of dishwasher salt, the consequences of using the wrong type, and how to properly add salt to your Bosch dishwasher.


The type of salt to use in a Bosch dishwasher is specifically designed dishwasher salt, not table salt. Dishwasher salt consists of sodium chloride, but it is in coarse granules to prevent clogging the dishwasher’s salt tank. Examples of compatible salts include Bosch Finish SGZ9091UC Dishwasher Salt and Impresa Dishwasher Salt. Using the correct salt type is crucial for the performance and longevity of your Bosch dishwasher.

Why Dishwasher Salt is Necessary in Bosch Dishwashers

Dishwasher salt plays a crucial role in Bosch dishwashers. It helps to soften hard water, which can cause dishes to appear dirty or be covered by a thin layer of minerals even after washing. Hard water contains high levels of calcium carbonate, also known as limescale. Bosch dishwashers have a built-in water softener that removes calcium and magnesium ions from the water, and dishwasher salt is used to regenerate the resin in the built-in ion-exchange system.

The coarse grains of dishwasher salt prevent it from clogging the softener unit, improving the dishwasher’s performance by reducing water spots and leaving dishes clean and spotless. It also helps prevent limescale buildup and acts as a water softener, especially in hard water areas. This results in cleaner dishes, a longer-lasting dishwasher, and spot-free glassware.

The Right Type of Salt for Bosch Dishwashers

Bosch dishwashers require dishwasher salt specifically designed for use in dishwashers. It consists of sodium chloride, but it comes in coarse granules to prevent clogging the dishwasher salt tank, unlike table salt, which is finely ground. Some compatible dishwasher salts for Bosch dishwashers include:

  1. Bosch Finish SGZ9091UC Dishwasher Salt
  2. Impresa Dishwasher Salt

These salts are compatible with various Bosch dishwasher models, including Bosch 800 Plus and ADA (SGE) dishwasher SKUs. It is essential to use dishwasher salt specifically designed for dishwashers and not table salt, as using table salt could damage the water softening system.

Consequences of Using the Wrong Type of Salt

Using the wrong type of salt, such as table salt, can damage your dishwasher’s water softening system. This is because table salt is much finer and can clog the salt tank in the appliance. Additionally, using the wrong type of salt can lead to poor cleaning results, as it may not effectively soften the water and allow the detergent to dissolve properly. To avoid these potential problems, it’s crucial to use the correct type of dishwasher salt.

How and When to Add Salt to Your Bosch Dishwasher

The frequency of adding salt to a Bosch dishwasher depends on the usage and water hardness in your area. It is generally recommended to check the salt level and refill it about once per month. Bosch dishwashers have a salt refill indicator on the control panel, which will light up when it’s time to refill the salt. To add salt, locate the salt reservoir at the bottom of the dishwasher, unscrew the cap, and fill it with special dishwasher salt.

Common Misconceptions About Dishwasher Salt

There are several common misconceptions about dishwasher salt. One misconception is that dishwasher salt is the same as table salt. While both consist of sodium chloride, dishwasher salt is coarser than table salt, which prevents it from clogging the dishwasher’s salt tank.

Another misconception is that dishwasher salt is harmful to the environment or the user’s health. In reality, dishwasher salt is not inherently harmful to the environment or health when used as intended. It’s not meant for human consumption, but it’s not harmful when used in a dishwasher.

Remember, the key to maintaining the performance and longevity of your Bosch dishwasher is using the right type of salt and adding it regularly. This not only ensures cleaner and spot-free dishes but also prevents potential damage to your appliance.
