How Hard Water Can Affect Your Dishwasher September 6, 2019

How Hard Water Can Affect Your Dishwasher, Wappinger, New York

Hard water has an unusually high level of minerals in it, such as magnesium, salt, and calcium. If you notice water spots on your dishes after you run the dishwasher, then your home likely has hard water. This can affect your dishwasher—and other water-using appliances—in a variety of ways. Here’s what you need to know about the impact of minerals and how a water softener can help.

A Guide to Your Dishwasher & Hard Water

The Impact on Your Dishwasher

As the water runs through your dishwasher, it leaves minerals behind. This mineral buildup occurs throughout the inside of the dishwasher and all the water lines. As the buildup grows, it will clog the lines. Water pressure is affected, as less water can move through the pipe. The dishwasher becomes less efficient and will work harder to clean your dishes, sucking up more energy and prematurely wearing out. Salt buildups also corrode any metal components, shortening your dishwasher’s life span.

How to Protect your Dishwasher

water softenerTo protect your dishwasher and your other water-using appliances, install a water softener. A softener uses an ion exchange technique to remove the calcium and magnesium from the water, leaving you with mineral-free water. Once you install the softener, your detergent will work more efficiently, and you’ll need less of it.

For a temporary solution before installing a softener, remove the mineral buildup with distilled white vinegar. Place two cups of it on the bottom rack in an open container, and then run it normally without the drying cycle. This will dissolve the minerals.
