There’s a side of coffee that rarely gets attention: the inside of the machine.
In Episode 1 of the Caffenu Technician Series, we partner with Brewfix to explore the role technicians play in maintaining performance, consistency, and long-term machine health.
From installation to after-sales support, their work goes beyond repairs. It’s about keeping machines operating as they should over years of daily use. When maintained correctly, coffee machines can last decades, but that longevity depends entirely on consistent care.
Inside the machine, small issues build over time. Coffee oils, residue, and scale don’t just affect hygiene they directly impact flow, temperature, and extraction. The result? Changes in taste, crema, and overall coffee quality.
One of the most common issues technicians encounter is temperature loss. Often mistaken for mechanical failure, it’s typically caused by scale build-up, something that can be resolved through proper descaling and routine maintenance.
The same applies to brewing performance. A neglected brew unit, worn grinder blades, or incorrect grind size can shift extraction dramatically, leading to weak, bitter, or inconsistent coffee.
These aren’t isolated problems. They’re connected.
And more often than not, they’re preventable.
This is where technicians step in, not just to fix machines, but to extend their lifespan and protect the quality of every cup.
