Is dishwasher salt necessary

Whether you need salt for your dishwasher depends on a number of factors. First, the hardness of the water in your community is important. You can easily check this online at your water supplier’s website.

Dishwasher detergent

In addition, the type of detergent you use is also important. Some dishwasher cubes already contain salt, so you do not need to add more salt. You can check the packaging to see if there is salt in the detergent.

Water hardness

If your water hardness is 21 °dH or lower, you do not need to add baking soda if you use a dishwasher detergent with salt. If your water hardness is higher or if there is no salt in the detergent, you do need to add salt.

Where in the dishwasher is the salt

The reservoir is located on the bottom of most dishwashers under the lower rack. So you have to take it out first before you can check if the reservoir is full. There is a cap on the reservoir and to check and replenish the salt simply unscrew the cap. You can use a funnel to pour the salt into the reservoir, but often the opening is large enough to do this without a funnel. After refilling, make sure you tighten the cap again.

 

Water Hardness

Your dishwasher has an option to adjust the water hardness. You can find out exactly how to do this in the dishwasher’s manual. If you set the water hardness correctly, your dishwasher can determine how much salt is needed to make the clean dishes free of white deposits.

Reservoir

The maximum amount of salt you can add is indicated on the reservoir. A new dishwasher will often tell you when it’s time to refill the salt.

Why you need to use dishwasher salt

The water your dishwasher uses to rinse your dirty dishes contains calcium. How much lime there is in your tap water depends on where you live. Water with a lot of lime is called hard water and this causes a white deposit on your glasses. Lime deposits can also damage the inside of your dishwasher. The lime particles can block the holes in the spray arms, for example, preventing the water from being dispersed properly.

Softening salt

To turn hard water into soft water, you need softening salt. This acts as a water softener that counteracts limescale. Keep in mind that this is specifically dishwasher salt, this is different from coarse salt or table salt.

Water Hardness

If your dishes still come out of the dishwasher with a white deposit, you may choose to set the water hardness on your dishwasher a little higher or use cubes of extra salt anyway.
