Features to Consider in the Best Coffee Maker for Hard Water
On top of the features, you might find in the regular coffee maker, a coffee maker for hard water will have some extra features to help eliminate limescale deposits for improved working efficiency and durability.
Furthermore, the table below breaks down these features for easier understanding.
| Coffee Maker for Hard Water | Construction Material | Water Filtration System | Power Saving Mode Timer |
| Nespresso Vertuoplus Coffee and Espresso Maker | Plastic | N/A | 9 min |
| Cuisinart Thermal Coffee Maker | Stainless Steel | Charcoal | N/A |
| Hamilton Beach Programmable Coffee Maker | Stainless Steel | N/A | 2 hours |

| Braun BrewSense KF6050WH Drip Coffee Maker | Stainless Steel, Plastic, Glass | Charcoal | 2 hours |
Self-Cleaning Feature
Even if the coffee maker has an advanced filtration system, there are chances of debris, dust, and limescale deposits seeping through the filtration system and getting into the carafe. Therefore, it is important to consider the self-cleaning feature as it will save you the hassle of manual and regular cleanups.
For instance, the Hamilton Beach Programmable Coffee Maker comes with a self-cleaning feature that ensures that you can use the machine regularly without worries of manual cleanups.
Water Filtration System
The effectiveness and efficiency of a coffee maker for hard water are mainly affected by how much dust, debris, and limescale it can filter out even if the machine has an automatic descaling feature.
Even if the coffee maker might have a self-cleaning feature, the mineral and impurity deposits can be overwhelming to the point that the machine will need to auto clean after every brewing cycle.
An effective water filtration system like the charcoal filtration system in the Cuisinart Thermal Coffee Maker can help to significantly reduce the limescale deposit entering the carafe.
Ease of Disassembling and Cleaning
Regardless of how advanced the self-cleaning feature is, the limescale deposits can be overwhelming if the water hardness levels are high, and you will need to clean the machine manually.
In most cases, you have to disassemble the coffee maker to access the internal components for cleaning. It is advisable to go for a coffee maker machine that is easy to disassemble, clean, and then reassemble.
Fortunately, the disassembling and assembling of the Mr. Coffee Programmable Coffee Maker is straightforward, and you don’t have to worry, even if you are a beginner. Typically, you can remove the water tank of this machine and then clean it in a dishwasher.
Cleaning Alerts
Most coffee makers for hard water that comes with a self-cleaning feature will need you to press a button to run it. Considering that you can’t see the internal components of the coffee maker, the limescale residues might be building up quicker than you expect.
That means you want to know the ideal time to start the self-cleaning feature. Going for a coffee maker with cleaning reminder alerts such as the Braun BrewSense KF6050WH Drip Coffee Maker is advisable.
Auto-Descaling Feature
In most cases, a coffee maker beeps a sound or displays an alert to remind you to run the self-cleaning feature when there is a limescale buildup. Considering that this feature varies with coffee maker models, you might not be familiar with the alert for that model.
That means the coffee maker might alert you to run the self-cleaning feature and end up not running it. You can avoid this problem by going for a coffee maker with an automatic descaling technology such as a Nespresso Vertuoplus Coffee and Espresso Maker.
The machine will detect the limescale deposits and then start the descaling mode with this feature. The main benefit of this feature is that the machine will clean itself when the residues reach a certain level, minimizing the chances of an extreme buildup of minerals and impurities.
Build Quality
The build quality of a coffee maker plays an important role in its usability and durability. For example, the construction materials of a coffee maker will determine whether you can clean it in a dishwasher or not.
Considering that the machine will be brewing hot coffee, the construction materials also need to meet food-grade standards. For instance, the stainless steel construction of the Cuisinart Thermal Coffee Maker ensures it is dishwasher safe.
Unlike plastic construction, stainless steel construction is also sturdy, and the machine can serve you for years without breaking down. It is also straightforward to remove an accumulation of limescale on stainless steel using water and white vinegar solution.
Coffee Capacity
Like any other coffee maker, capacity is vital when choosing a coffee maker for hard water. In most cases, the size of a coffee maker will depend on your family size and the number of coffee cups you might want to prepare at a go.
For example, if you have a large family or are simply a coffee lover, you can go for a 12-cup coffee machine such as the Hamilton Beach Programmable Coffee Maker. Keep in mind that a large coffee maker will take longer to complete a brewing cycle.
Form Factor
When choosing a coffee maker for hard water, you should consider its overall size in external dimensions. Typically, the physical size of a coffee maker will determine how much kitchen counter space will take.
For instance, the slim and compact form factor of the Hamilton Beach Programmable Coffee Maker allows it to fit almost anywhere in your kitchen. Also, the swing-open brew-basket design will enable you to keep this coffee maker even in the cabinet.
Power Saving Mode
The power-saving mode helps shut off a coffee maker after a certain period of inactivity. However, this feature varies between coffee maker models, and some will take longer before shutting off than others.
The Mr. Coffee Programmable Coffee Maker takes around four hours of inactivity to turn off, whereas the Nespresso Vertuoplus Coffee and Espresso Maker takes about nine minutes of inactivity to shut down.
Energy Efficiency
Usually, a coffee maker keeps coffee warm. Various coffee maker models achieve this using different techniques, and some are more energy-efficient than others. For instance, the Cuisinart Coffee Maker improves energy efficiency using a double-walled insulated thermal carafe instead of a warmer.
