What Type Of Dishwasher Is Best For Hard Water?

Dishwasher Is Best For Hard Water

We admit that there are hundreds of dishwasher brands on the market. But not all can match your needs to get a good dishwasher for hard water.

You will be considering unique features such as the ability to clean dishes with well water. There are three qualities that you will weigh before buying a dishwasher for hard water;

1. Advanced Filtration System

A dishwasher with a strainer system is excellent. It removes particles and compounds for hard water use. Your priority is to leave no spots and film on your dishes. Get a machine with an ultrafilter system to get rid of water contaminants.

2. Stainless-steel Drum

The ideal material for a dishwasher drum/tub is stainless steel. Some other materials will resist high water temperatures and allow slow condensation. Stainless steel dries faster and is an exemplary heat resistor. The qualities ease the more rapid dissolving of hard water minerals.

3. Rinse Aid Function

A perfect dishwasher should rinse your utensils off the soap and hard water deposits. The Rinse Aid Function is an added benefit in dishwashers. It is a technology for stripping off chemicals. It ensures your tableware is spotless and crystal clear.

Now you know the ideal dishwasher for hard water!

Benefits Of Hard Water Dishwashers

Benefits Of Hard Water Dishwashers

Hard water is detrimental to human health. And to all household appliances, including your dishwasher. The residues, salts, and scum buildup create an extra layer on the tub. That dwindles its performance.

Also, your utensils will likely come out with a cloudy layer. You will witness your clear glasses and bowls turn opaque. It will be a matter of that you will be struggling to descale your unique dishes. Luckily, hard water dishwashers have helped countless households to overcome these woes. In a nutshell, here is what you will reap upon purchasing a hard water dishwasher;

1. Longer Lifespan

Studies reveal that hard water damages dishwashers. It shortens its lifespan from 10 to seven years. That’s an immense loss bearing in mind the cost of the unit. Beware that some models cost up to $3500 or more! A regular dishwasher lasts a few years in places with no soft water.


  • Advanced filtration technology.
  • Rinse action technology.
  • Durable stainless-steel interior.

If you are lucky to get the above qualities in your appliance, you will get a long-lasting washer.

2. Saves You Money

Indeed, dishwashers do break down due to hard water use. Replacing the washer is not a cheap affair. It is also expensive to maintain a regular dishwasher. Professional descaling and heating coil replacement are costly.

A Hard water dishwasher remains unaffected by chemicals and deposits. And as we mentioned earlier, it can live in your kitchen for ten years or more. So, if you can afford it, go for a hard water dishwasher and save your dollars.

3. Clean Dishes

Have you ever dined on spotty and cloudy dishes? Of course, it didn’t go well as you kept figuring out that the dinner plates and cutlery weren’t clean. The disgusting opaque, and spotty appearance signifies that the faucet water is hard. And if it is happening in your home, you need to change the dishwasher.

Buy a unique dishwasher to get one that strips your utensils from dirt. The ideal machine should not leave scum, residues, and opaque layers on your dishes.

A unique dishwasher should clean, sterilize, and dry your utensils. That’s a must-have quality if you live in hard water regions. So, a hard water dishwasher cleans dishes with an extra touch.

4. High Performance

Most Dishwashers for hard water have a wide variety of washing cycles. That’s an excellent indicator of performance. Also, the machine has embedded technology. It doesn’t need boiling water to dissolve minerals.

Your delicate dishware is safer in the tub as the cleaning process is gentle. Also, you do not have to put up with residues on your dishes. The water settings are enough. And come with a rinse aid that ensures your fragile dishware is dry and spotless.

5. Extra Features

Dishwashers for hard water have more features than regular ones. The most common high-tech functionalities include CrystalDry. The feature cleans dishware up to 60 percent dryer. Another feature is PureDry technology, which can clean your utensils up to 162 F degrees.

Dishwasher performance varies in cycles. Generally, there are the basic ones. These have limited operations. Those with 14 to 16 cycles have more processes and are better. You are battling with loads of hard water deposits and chemicals to clear.

How Can I Make My Dishwasher Work Better With Hard Water?

How Can I Make My Dishwasher Work Better With Hard Water

Buying the ideal dishwasher for cleaning with hard water is crucial. Hard water diminishes the heating appliance by crusting it. The chalky minerals corrode the interiors, especially those that are not rustproof. Once you get your perfect washer for hard water, you still need to have a duty to perform. Make the washer function better and last longer. Here are several ways to help your dishwasher performance with hard water;

Use A Descaler

Running your dishwasher with vinegar is an excellent practice. It deep cleans the interior and boosts performance. Vinegar is a standard household solution that clears hard water stains. It peels off calcium deposits from the tub walls and the racks. Pour vinegar into a cup and insert it on the top shelf. Run a regular cycle to clean your dishwasher interiors.

Fit A Water Softener In Your Home

Our recommendation to households with hard water challenges is a softener. Fit your home with a water softener to safeguard your appliances. Your dishwasher will no longer crust or corrode. It is also healthy for consumption as it has less fluoride.

Use Detergents With Softeners

When selecting dishwasher detergent, consider those with high phosphate levels. Phosphate is a hard water softener. It also improves dishwasher performance and gives you sparkling results.

Add Rinse Aids

Rinse aids assist your dishwasher in cleansing limescale deposits on your tableware. The cleansers remove chemical residues from your dishwasher as you rinse your utensils. That leaves the tub clean and free from chemicals that cause crusting.

Use Suitable Detergent And Levels

Wrong may cause your appliance to underperform. Excess detergent in your dishwasher creates extra foam/suds. The extra suds dwindle your appliance’s performance and reduce its rinsing capacity. You will end up running many rinsing cycles, which is uneconomical.

How Long Does A Dishwasher Last With Hard Water?

Laboratories experiments have revealed that hard water has dense concentrations of essential minerals. The significant components are magnesium and calcium. Though the elements are necessary for the human body, fluoride is more harmful. Also, the impact on appliances is devastating.

Your dishwasher’s lifespan gets affected by 30-50%. Manufacturers give your dishwasher a lifespan of 10 years. That is while operating it with soft water. The same appliance will live seven years if your household uses hard water.

Is Hard Water Bad For Your Dishwasher?

Hard water is harmful to your dishwasher. And other appliances too. The mineral deposits cause crusting on the element and interior layer. That results in corrosion. The effect on your dishwasher is a reduction in lifespan. There are other costly maintenance processes. You have limited choices but to use what your county/state provides. But you can lessen the salts that affect your dishwasher. Use recommended softeners.

  1. Use hard water softeners.
  2. Descale your dishwasher with vinegar.
  3. Use the proper detergents.
  4. Add rinse aids when running the dishwasher.
  5. Buy a dishwasher with advanced technology for hard water cleaning.
