Best Washing Machines For Hard Water [Our Top Picks]

Besides washing detergents, washing with hard water can have several effects on both your clothes and washing machines. 

Hard water can cause your fabrics to become stiff and cause tears in fibers. It also leads to scale deposits on your washing machine, which reduces the life of your machine. 

You need the right kind of washing machine that can withstand hard water and remain effective for longer. 

There are several washing machines that are designed to withstand the effects of hard water. This article will highlight the best machines that work well with hard water.

What is Hard Water?

Hard water is water that contains dissolved minerals. Hard water gets its minerals from the soil and rocks, especially where the water is collected. Most of the salts present in hard water are calcium and magnesium. It is worth noting that the hardness of water comes in degrees. Depending on where you live, you should expect the water to have a degree of hardness. Soft water is water that has less calcium and magnesium minerals.

Most of the calcium and magnesium salts in hard water are mainly bicarbonates, sulphates, and chlorides. In most cases, you may also find iron. Ferrous iron contained in hard water is oxidized and will leave stains that are reddish-brown in white fabric. 

Hard water that is mainly associated with calcium bicarbonate is termed temporarily hard. This is because boiling is enough to break down the bicarbonate bonds to form calcium carbonate, which is insoluble in water. However, boiling is not sufficient to remove hardness from the other salts present in hard water. 

This is permanent water hardness. When hard water reacts with soap, it forms an insoluble scum. Scum is a gelatinous curd that arises from the reaction of long-chain fatty acids with calcium and magnesium ions in the hard water. However, some modern detergents are designed to minimize the formation of scum.

Effects of Hard Water on Your Laundry

Hard water takes a toll on your laundry if you don’t find ways to manage the stain-causing salts. You can use these as signs to determine whether you have hard water in your supply. Most people report that hard water causes skin irritation when used in laundry. 

This may be caused by bacteria build-up associated with limescale. However, the characteristic that gives away hard water when you are doing your laundry is that it does not form lather with detergents and soaps easily. 

Shampoos are ineffective because of the salts present. Hard water also gives your fabrics a stiff texture, and you may feel that they seem dirty even after thoroughly washing them. 

Hard water is known to discolor fabric, especially bright colors. Doing laundry with hard water may cause your fabric to tear easily. 

Generally, hard water makes it much more difficult for you to clean your laundry because it does not lather easily with most soap brands. 

The scum that is produced causes damage to your clothes and can lead to permanent stains. In some instances, the scum might require you to rewash your clothes. 

Once your clothes have dried, you may realize that they are stiffer and may cause skin irritation if you had washed them with hard water. 

Hard water also damages darker fabrics because it encourages premature fading. The high iron levels found in hard water will make the clothes have streaks or spots that are reddish-brown and almost impossible to get rid of. 

If the hardness of your water is at extreme levels, the salts present will make the fibers of your clothes weaker and prone to tear. If you wash your clothes regularly with hard water, you may notice that you require repairs or replacement frequently.

Effects of Hard Water on Washing Machines

Hard water is quite destructive to most home appliances. Washing machines are particularly exposed to damage from hard water. The first problem that you will encounter when using hard water with your washing machine is that you will require more water and detergent to wash the clothes. 

This is because hard water contains chemicals that interfere with the proper working of your detergent—all this works to increase the energy that is required to clean your clothes. 

Having to use more electrical power every time is one of the contributing factors that cause the laundry machine to have a reduced lifetime. 

Hard water is also responsible for the build-up of limescale in different parts of your washing machine. This may attract expensive repairs. 

Limescale build-up will greatly lower the efficiency of your washing machine by increasing the energy expenditure. Most of the limescale accumulates on the heating component, which will now be covered in a layer of limescale. 

Limescale is a poor conductor of heat, and a lot of energy will be wasted in heating the limescale up that then indirectly heats the water. 

The heating element of your washing machine will be overworked, increasing the likelihood of burning out. The degree to which limescale accumulates in washing machines will depend on the hardness of the water that you use. 

Water that has extremely high levels of calcium and magnesium salts will increase the rate at which limescale accumulates on the heating element and other parts of your washing machine. 

The limescale will continue to build up, and you may be required to do periodic descaling to improve the efficiency of your washing machine. All this makes laundry tiresome, forcing you to look for better alternatives.

Can Ordinary Washing Machines Handle Hard Water?

Ordinary laundry machines perform quite poorly when used with hard water. However, there are tips and tricks that you can use to make this a little easier. One way of doing this is by picking the right kind of detergents to use with hard water. 

You can also choose to buy water softeners that you will add to the clothes as you wash them. An ordinary washing machine can perform better if you use the right amount of softener or a detergent that has this property. 

All kinds of ordinary washing machines will soon get covered in limescale, requiring you to descale them once every few months. This is especially the case when you have a machine with the heater component installed for spin-drying. 

If you’re going to use an ordinary washing machine with hard water, it is recommended that you do monthly descaling.

One of the biggest issues that you will face when using an ordinary washing machine with hard water is that other components of the machine will get clogged and, in extreme cases, cause failure. 

Limescale will gradually accumulate in areas like the pump mechanism, lint screen, and washing tub, among other moving components of your washing machine, and cause friction and damage.  

Using hard water with an ordinary washing machine also poses a risk of damage to the valves, waterline, and the hose that supplies it. The salt component of hard water also increases the rate of rusting that poses a danger to any metallic parts of your washing machine. 

When the supply hose of your washing machine gets clogged, the water flow rate will be highly reduced, and this also increases the likelihood of water damage to your property. 

Even though it is quite possible to use an ordinary laundry machine with hard water, this has been shown to highly reduce its lifespan from an average of eleven years to about seven years.
