Unfortunately, hard water in your dishwasher can leave even the cleanest dishes looking cloudy and streaked. We've got a fix for that: add dishwasher salt to your machine once a month and revel in the shine.
Will my dishwasher stop working without salt? While it won't stop immediately, running your dishwasher without salt can significantly reduce its effectiveness and its lifespan due to scale build-up.
Most machines have an indicator light that will go on when you switch your machine on to let you know its running low on dishwasher salt. If the light is not on, this usually means that your machine has enough salt to wash another load of dishes.
Regularly check the salt levels in your dishwasher to ensure optimal performance. Refill the salt compartment whenever it runs low, typically every 1-2 months, depending on your water hardness and dishwasher usage.
Refer to the manual of your device to check its correct water hardness settings. Your dishwasher allows you to choose the dose for the amount of salt released each cycle. If too much salt is used, the dishes may have white marks and a salty taste.
So you might wonder: do I need dishwasher salt if I use tablets? It depends on your water hardness. If you live in a hard water area, salt is essential – for spotlessly clean glasses every day and an appliance that will work reliably long term. In moderately soft areas, all-in-one dishwasher tabs suffice.
Not using rinse aid decreases the drying performance of your dishwasher. It might also leave water spots on your dishes, especially if you have hard water. How often should I put rinse aid in the dishwasher? When the rinse-aid refill light appears on the control panel, the rinse aid will suffice for one to two loads.
"Rinse aid can help with drying and prevent water spots, especially if you have hard water—it can also make your dishes shine." While most dishwasher manufacturers expect owners to use rinse aid, it's not required: "You can skip it if your dishes are clean and dry without it," says Fleming.
An incorrect water hardness setting can also cause poor washing results due to too much salt being present in the machine. An indication of this is small drop marks being left on items, particularly glassware. On modern machines, the water hardness is adjusted using the controls on the front of the machine.
If your water is very hard, the built-in rinse aid in all-in-one tablets may not be enough to prevent water spots and streaks on glassware and dishes. In such cases, adding a dedicated rinse aid can enhance drying performance and improve the overall finish of your dishes.
If your water supply is hard, you will need to soften the water before using it in a dishwasher. Hard water is full of lime, which can damage dishes. Adding salt to the dishwasher helps to soften the water! Whether or not you need to use dishwasher salt will depend on the hardness of your water supply.
Salts made for dishwashers are designed to soften the water, so it is important to find an alternative ingredient which has the same effect. If your appliance is low on salt and you're caught short, the best alternatives are large grained “kosher” salt or white vinegar.
Using too much rinse aid with soft water will leave a residue in the dishwasher tub after running a cycle. Refer to the image below. Reduce the rinse aid setting to eliminate the rinse aid residue.

After a new round of testing, Cascade Free & Clear ActionPacs are still our top pick, and Cascade Platinum Plus ActionPacs remain our runner-up pick.
Dishwasher salt is sodium chloride, the same chemical that makes up table and sea salts. You shouldn't use table salt though as it is much finer and can block and cause damage to your dishwasher. Dishwasher salt granule size is larger and ensures the salt dissolves slower without blocking the softener unit.
We recommend leaving the salt level approximately 1cm under the lip of where the cap will screw back on so you don't overfill your machine and potentially waste your product.
A monthly top-up is recommended. No watermarks on your glasses and dishes – the easiest way to check if you need a salt top-up is to inspect your glassware. If you find any watermarks or spots, this means the water used by your dishwasher has gone quite hard.
Vinegar can be used as a temporary fix if you run out of rinse aid, but prolonged use is not recommended. The acidity in vinegar can limit the cleaning power of the detergent and can also lead to premature deterioration of rubber seals and gaskets inside of your dishwasher.
Luckily, all Cascade dishwashing products are formulated with built-in rinse aid action. And if you want additional protection, there's Cascade Power Dry Rinse Aid. Just add it to your dishwasher's rinse-aid dispenser and it's automatically released into the rinse cycle.
Here at Bill & Rod's Appliance, Inc. we do not want to keep it a secret any longer and want you to be in the know. It is simply white vinegar. That's right, just white vinegar will achieve the same results without chemicals and at a fraction of the price.
If you find that your dishes are coming out streaky or gritty instead of sparkling clean, you might be running low on salt.
Although they have been generally declared as “safe to use”, ingesting these chemicals over a prolonged period of time may cause adverse health effects–especially for sensitive groups. In addition, many of the chemicals in rinse aids are toxic to aquatic life and bad for the environment (8).
Dishwasher salt softens the water entering your appliance, helping dishwasher detergent to dissolve during a wash cycle. Without dishwasher salt, the pipes and valves in your appliance can become clogged with limescale, leading to leaks and reduced water flow.
