If you’ve ever wondered if dishwasher salt is important, the answer is YES! It’s often overlooked, but it plays a crucial role: it helps combat limescale, ensuring effective washes and helping your dishwasher run efficiently over time.

Let’s find out in detail what it’s for, where it should be inserted, and how often!

What is dishwasher salt used for?

Salt isn’t used to wash dishes, but to soften the water used during wash cycles . In fact, water can contain high amounts of limescale, which, over time, builds up inside the dishwasher and on dishes, causing:

  • streaks and stains on glasses and plates.
  • Less effective washing performance .
  • Increased wear of internal components.
  • Possible faults due to limescale build-up.

Salt helps reduce water hardness and protect your dishwasher , helping to maintain high washing performance over time.

Where do you put salt in the dishwasher?

Every dishwasher is equipped with a dedicated salt reservoir, generally located on the bottom of the appliance, under the lower basket.

To add it, simply remove the lower basket, unscrew the reservoir cap and pour in the salt using the appropriate funnel.

NOTE: Use only dishwasher-safe salt . Table salt, while similar in appearance, may contain additives that could prevent your water softener from working properly.

How often should salt be added?

There’s no one-size-fits-all answer. Frequency depends mainly on two factors:

  • The hardness of the water in your area.
  • How often you use your dishwasher.

On average, a family that uses the dishwasher every day may need to refill the salt every 4-8 weeks , but the frequency may vary depending on water characteristics and usage habits.

Newer dishwashers display a low salt indicator light. If you have a Haier, Candy, or Hoover dishwasher connected to the hOn app , you won’t have to remember to check the salt level manually: the app notifies you when it’s time to refill and lets you check the level at any time.
