Tired of your dishwasher turning your dishes into a chalky mess? Or maybe your washing machine is turning your whites dingy gray? It’s not just your imagination — it’s hard water. This mineral-rich menace is causing more damage to your appliances than you might think. Let’s dive into how to protect your appliances from hard water.
Understanding Hard Water
Water with calcium or magnesium concentrations of more than 7 grains per gallon (gpg) qualifies as hard water.
Over time, these minerals can build up in appliances, creating a scale that can potentially clog pipes, reduce efficiency, and even shorten their lifespan.
You'll know you're experiencing hard water in your washing machine, dishwasher, or other appliances if you see these signs:
- Spotty dishes
- Dry skin
- Fading clothes
- Clogged pipes or reduced water flow
- Reduced appliance efficiency
- White residue on your faucets, showerheads, and other fixtures
Protecting Dishwashers and Washing Machines from Hard Water
Hard water and dishwashers don't mix. Neither does using hard water in a washing machine. Here's how you can protect these appliances from hard water damage.
- Use a water softener or salt-based water conditioner: Water softening removes the minerals that cause hard water, making your water softer and more gentle on your dishwasher and washing machine. A salt-based water conditioner works similarly, using salt to exchange the hard water minerals for softer ones. They both keep your washer running smoothly — and prevent your clothes from fading so quickly.
- Clean the machines regularly: Just like any appliance, your dishwasher and washing machine need a little TLC. A deep clean with a dishwasher cleaner every few months can help remove any stubborn mineral buildup. On your washing machine, regularly clean the detergent dispenser, rubber seals, and drain filter to remove any residue or debris.
- Avoid overloading: Don't stuff your dishwasher to the brim. Overloading prevents water from reaching all the dishes, leading to poor cleaning results. Same goes for your washing machine. Washing machines work best when laundry items have enough space to move around. Overloading your washing machine can lead to excessive wear and tear.

Additional Tips for Hard Water Areas
While water softening and filtration are the go-to ways to fight off hard water, you can also switch to detergents and cleaning products specifically designed for hard water. Also, stay away from detergents marked as "gentle," as research has found these typically don't fare well with hard water.
You might also consider avoiding hard water when cooking and drinking. Hard water doesn't have any known adverse health effects, but it can taste off and leave your dishes covered in film. Using an under sink water filtration system will help to improve the taste and also leave you with less of a mess to clean up.
