The salt you pour in the softener unit never actually touches your dishes it just stays in the unit itself. If your dishwasher doesn’t have indicator lights, it’s a good idea to refill the salt about once per month.Īnd only put salt into the softener unit. Most dishwashers also now have a salt refill light.
Then consult your dishwasher’s manual to find out which setting will work best. You'll be able to find the concentration of calcium and magnesium ions, usually in millimole per litre (mmol/l). To find out how hard the water in your home is, consult your water supplier – you can usually find the information online.
You can often adjust the salt setting on your dishwasher to suit the hardness of the water in your area. The amount you put in depends on your dishwasher, so there’s no precise measurement for this process. Only fill up the salt to the water level inside the salt compartment. You'll need to pull out the lower rack to access it, and you should have a small funnel that came with your dishwasher to help make sure all the salt goes in the hole.
Your dishwasher's salt compartment is normally at the bottom of the machine, near the filter.
