Not all dishwashers require salt. The need for salt depends on the type of dishwasher you have and the water hardness in your area.
- In regions with very hard water, using a dishwasher with a built-in water softening system is highly beneficial, and these models typically require dishwasher salt to function effectively.
- Some dishwashers come equipped with an ion-exchange water softening system, specifically designed to remove calcium and magnesium ions from the water, and these systems often require the occasional addition of salt.
- Conversely, dishwashers without a built-in water softening system might not necessitate the use of salt. However, they may still benefit from it if the water supply is hard.
Determining Water Hardness
Before deciding whether to use salt in your new dishwasher, it’s crucial to determine the hardness of your water. Water hardness is measured in parts per million (ppm) of calcium carbonate (CaCO3) or in grains per gallon (gpg). The classification of water hardness varies but is generally categorized as follows:
Water Hardness Classification
| Water Hardness | Measurement in ppm | Measurement in gpg | Description |
| — | — | — | — |
| Soft | 0-60 | 0-3.5 | Little to no scaling |
| Moderate | 61-120 | 3.6-7 | Some scaling, potential issues with appliances |
| Hard | 121-180 | 7.1-10.5 | Visible scaling, significant impact on appliances |
| Very Hard | Above 180 | Above 10.5 | Heavy scaling, major issues with appliance efficiency and longevity |
If your water supply falls into the moderate to very hard category, using a water softening system, either as part of your dishwasher or as a whole-house system, can significantly improve the performance and lifespan of your appliances.
