What Is Hard Water?

Hard is water that has a high percentage of dissolved minerals and salts. These minerals and salts include calcium, magnesium, lime, and chalk. 

When it rains, the water is soft, meaning that it doesn’t have minerals, but when it gets on the earth’s surface, it gets mixed with the minerals, making it hard. 

Is Hard Water Bad For Washing Machines?

Hard water is bad for your washing machine. It leads to the accumulation of limescale on the heating unit. The buildup becomes an insulator causing the heating unit to overheat. Overheating the heating unit can lead to premature machine breakdown.

Impact of Hard Water on Your Laundry

Hard water makes your clothes look dingy due to mineral deposits. This is because of the film and soap scum created by the minerals. The reaction of minerals and soap causes scum. 

Why Is Washing Machines With Hard Water Filter Important?

A washing machine with a hard water filter is important because it passes the hard water through a filtration process, which removes all the minerals from the laundry water. 

The filtration process safeguards your machine heating system from damage; however, it is important to note that there are specifically no washing machines with an inbuilt hard water filter. 

The filter comes separately, and you attach it to the water tap before your washing machine’s faucet connector.

How To Protect Washing Machine From Hard Water

If you only have hard water for your laundry, there are several ways you can protect your washing machine from hard water. That will include using a hard water filter, regular care during and after every wash, and routine maintenance when there is an accumulation of limescale on your machine’s heating system. 

  1. Hard Water Filter

You fix a hard water filter on the tap just before the washing machine’s water inlet connector. It is specially designed to filter the hard water minerals components and salts. 

The tiny appliance makes sure your laundry water is soft before it gets into your washer. You can order that online from stores like Amazon. 

The filter will come with a manual on how to fix it on your water tap. An example is the Purifit and Water Science CLEO, all available on Amazon.

2. Special Hard Water Softening Powders And Tablets

Many companies have come up with special chemical combination powders and tablets for protecting your washing machine from hard water. They come with specific instructions on how to use them, but mostly, you will combine them with your laundry. 

The chemicals protect your washer’s heater system from limescale which causes machine breakdown. You can order these online or get them from your local supplier.

3. White Vinegar

White vinegar is a magical liquid. It has got many uses at home. One of those is to protect your appliances from hard water. It is an alternative to harsh powders and tablets that may be dangerous when handling. 

When running a wash, pour a cupful of vinegar into the washer. Dilute the vinegar with water and add in detergent. 

Vinegar controls the accumulation of limescale as a result of hard water. The simple solution also kicks of smell and bio-film from your washer.

4. Routine Washing

Another way to protect the washing machine from hard water includes routine maintenance. It involves a detailed but straightforward few steps here;

Step 1: 

Pour in a cupful of vinegar or lime solution and run a hot water cycle.


Unplug your washer from the power source. Detach the fabric softener tray and wash it thoroughly in hot soapy water mixed with detergent. Use a cleaning solution to work on the bleach dispenser. 

Clean up the drum and fix back both the fabric softener tray and the bleach dispenser. Plug on the empty washer and run a hot water cycle again. 

Step 3:

Use a special washing machine powder like washer magic to clean the outside. Wipe the washer with a clean, dry cloth.

How Do You Soften Hard Water In A Washing Machine?

If you live in hard water areas and you don’t have a hard water filter installed on your tap, you can soften water directly in your washing machine. That can go a long way to protect your washing machine from limescale accumulation on the heating unit. The accumulation causes overheating, which can be irreversibly damaged.  

Here is how to protect the washing machine from hard water by softening hard water in a washing machine.

  • Using a commercial hard water softener is the best and guaranteed way to remove and neutralize the minerals present in the laundry water hard. They come in powder and tablet form. The water softeners will prevent the accumulation of limescale and get rid of odors from your wash drum. 
  • Add half a cup of white vinegar into your laundry when doing the last rinse. The vinegar’s acidic nature will dissolve calcium in the hard water and make the water soft.

If you find yourself using hard water on your clothes, you can put half a cup of baking soda in your wash drum together with your laundry. Set the washer at your desired wash cycle and run it until the cycle is complete. 

The softened water will clean your clothes and rinse them effectively. Note that the baking soda will not filter the minerals out; therefore, this is meant to rinse the soap scum off your clothes.
