Where Do You Put Dishwasher Salt? Top Tips for Spotless Dishes
Dishwasher salt is added to the softener unit, typically located at the bottom of the dishwasher, underneath the bottom rack. Remove the cap, pour in the salt until the reservoir is full, and replace the cap securely.
Understanding Dishwasher Salt and Its Purpose

What Is Dishwasher Salt?
Dishwasher salt is a particular type of salt used in dishwashers to soften hard water.
Unlike table salt, dishwasher salt has larger granules and does not contain additives like iodine or anti-caking agents. This purity ensures it dissolves slowly without clogging the softener unit.
The Role of Dishwasher Salt in Water Softening
Hard water contains high levels of calcium and magnesium, which can affect the cleaning efficiency of your dishwasher.
Dishwasher salt works by regenerating the ion exchange resins in the water softener, swapping calcium and magnesium ions with sodium ions, and thus softening the water.
Protecting Your Dishwasher and Dishes
Softened water not only improves the cleaning performance of your dishwasher but also prevents limescale buildup, which can damage the appliance over time.
Additionally, it helps in avoiding water spots and streaks on your glasses and dishes, ensuring that they come out looking sparkling clean.
Locating the Dishwasher Salt Compartment

General Guidance for Salt Compartment Location
In most dishwashers, the salt compartment is located at the bottom of the machine, beneath the bottom rack. It is typically covered with a screw cap that can be easily removed when you need to add more salt.
Variations Across Different Models and Brands
While the general location of the salt compartment is consistent, its exact position and design can vary. Some dishwashers may have a more concealed compartment or use a different type of lid, depending on the brand and model.
Tips for Identifying the Salt Compartment
If the salt compartment is not immediately visible, look for a cap or knob at the base of your dishwasher, which may be labeled ‘salt’ or have a symbol resembling a diamond or a flower. Consult your dishwasher’s manual if you are unsure of its location.
Filling the Dishwasher Salt Compartment

Step-by-Step Salt Addition Instructions
To add salt to your dishwasher, start by removing the bottom rack to access the compartment.
Unscrew the cap, and if your dishwasher has a funnel, use it to pour the salt directly into the softener unit. Fill the compartment until it’s full, being careful not to overfill, and then securely replace the cap.
Choosing the Right Type of Salt
It is essential to use a specific dishwasher salt, as table salt or sea salt can damage the water softener. Dishwasher salt typically comes in large, chunky crystals, which are the most effective at regenerating the ion exchange resins.
Maintenance: Refilling Frequency and Indicators
Most dishwashers will have an indicator light or alert to let you know when the salt level is low.
It is generally recommended to check the salt level monthly and refill as needed to maintain optimal performance. After refilling, run a short wash cycle to remove any salt that may have spilled.
