Brewing Performance

With 19 bars of pressure and a fast 25 second heat up time, the Crux 17642 espresso coffee machine can produce premium tasting espresso similar to what you would get from your favorite coffee shop. The espresso comes out smooth and full-bodied with a nice crema on top. The single and double shot volumes are programmable, allowing you to customize the brew size.

The Science Behind Espresso Extraction

Understanding the science of espresso extraction can greatly enhance one’s appreciation of the Crux 17642’s capabilities. Espresso is created by forcing hot water through finely-ground coffee at high pressure. This process, known as extraction, pulls flavors, oils, and aromatics from the coffee grounds. The 19 bars of pressure mentioned in the Crux 17642’s specifications is significantly higher than the minimum required to make a true espresso, which stands at 9 bars. This ensures a richer and more intense flavor profile, characteristic of premium espresso shots.

Ease of Use

Operation is simple with one-touch buttons for espresso and lungo. The buttons can be programmed for your desired shot volumes. Cleaning is also easy since the water tank and drip tray conveniently detach. The capsules are inserted into the top of the machine. Used capsules are ejected into a holding tank that needs to be emptied occasionally.

Performance - Pressure for Perfect Espresso

With 19 bars of pressure, the Crux 17642 espresso coffee machine extracts the ideal aromatics and flavors from Nespresso pods to create exceptional espresso drinks. The fast heat-up system is ready for coffee brewing in just seconds. Choose between single or double shot volumes.

Brewing Capabilities

The Crux 17642 espresso coffee machine is compatible with Nespresso Original capsules to brew your preferred espresso, lungos and other coffee styles. It cannot use ground coffee or other capsule systems.

Coffee Quality

The 19 bars of pressure and fast heating system extract bold and aromatic espresso with a rich crema layer on top. The resulting coffee has an intense, robust flavor.

Water Tank

The 24oz (710ml) water tank allows brewing 3-4 shots before refilling. For daily use, the tank should be refilled every 1-2 days.

Pressure & Temperature

It generates 19 bars of pressure and uses a thermoblock heating system to quickly achieve optimal brewing temperature.

Innovation

The Crux 17642 espresso coffee machine’s rapid water heating allows coffee brewing to begin in just 25 seconds, much faster than competitor models.

Advanced Cleaning Features

The Crux 17642 espresso coffee machine not only prioritizes brewing quality but also emphasizes ease of maintenance. Its removable components, such as the 24oz water tank and drip tray, are dishwasher safe, simplifying the cleaning process. Furthermore, the machine’s intelligent descaling alert system is a standout feature. It notifies users when it’s time for a descaling cycle, ensuring the machine’s longevity and consistent coffee quality. This automated alert system reflects the machine’s user-friendly design, catering to both novice and experienced espresso enthusiasts.

Noise:

The Crux 17642 espresso coffee machine produces approximately 65-70 decibels of sound when brewing. This is comparable to other domestic espresso machines. The noise comes mainly from the internal pump which provides the 19 bars of pressure for espresso extraction. While not silent, the noise level is reasonable and less than many full-size automatic machines. The pump sound is a low hum that runs for about 30 seconds when pulling a shot. For most home kitchen use, the noise should not be disruptive. However, some users may prefer a quieter machine if making early morning coffee while others are sleeping nearby. Considering its affordable price and small size, the moderate noise output is understandable.

Safety

The housing is BPA-free plastic and the machine meets electrical safety standards.

Power

It has a 36 inch power cord and consumes 1450 watts. There is no auto shut-off feature.

Maintenance

Descaling every 2-3 months is recommended. No other regular maintenance is required besides rinsing and wiping.

User Feedback Analysis:

Reviews of the Crux 17642 espresso coffee machine show a range of customer experiences. Positive feedback from satisfied buyers praise the convenience, ease of use, and portability of the machine. Many like the fast heat up time, compact size that saves counter space, and quality espresso it brews from Nespresso capsules. Customers mention it’s an affordable option compared to higher-end Nespresso makers while still delivering delicious coffee drinks.

However, a common complaint from critical reviewers is water leaking from the machine. Several users reported defects causing internal water lines to disconnect and spill water within the housing. This points to potential quality control issues with a subset of units that slipped through before shipping. Thankfully, the water leaks out of the exterior vents rather than onto the counter. But it still results in a non-functional device that requires replacement.

Beyond the water leaks, some reviews suggest improvements like making the espresso hotter, reducing the noise during brewing, and using a larger used capsule container. The machine appears louder than some buyers expected for home use. And the espresso it brews may not be piping hot for those who prefer extra high temperatures.

In summary, when functioning properly the Crux 17642 espresso coffee machine earns praise for being an affordable, compact, and easy-to-use single serve espresso maker. But quality control problems causing internal water leaks disappoint a number of customers who receive defective units. Addressing these manufacturing issues would improve overall satisfaction and ratings.

  1. Drip coffee maker: Also known as American-style drip coffee makers, which brew coffee by sending hot water through ground coffee beans.
