How to Fix Water Settings in a Whirlpool Dishwasher

Hard water, simply put, is water with high levels of natural minerals such as calcium and magnesium. Appliances operating in hard water areas tend to develop calcium carbonate concretions faster than those in soft water areas. Using rinse aid in your dishwasher helps prevent spots from appearing on glassware as a result of hard water. The harder the water, the more rinse aid you will need. Adjusting the level of rinse aid used in each wash based on the hardness of the water supply is not complicated.
