My Rocket R Cinquantotto started having a major issue where the dual boilers weren’t maintaining their individual temperatures correctly and the PID was throwing errors. I live in Mooresville and was worried about finding a technician who understands the technical complexity of this high-end home machine. The technician was incredibly professional and performed a full diagnostic to find a failing solid-state relay and a clogged vacuum breaker. He replaced the parts and also updated the firmware to the latest version while the machine was open. It is rare to find such high-quality coffee machine repair for premium residential gear in the Charlotte area. The service was fast and my Rocket R Cinquantotto feels much more stable now than it has in months. Highly recommend for any serious home barista.

The rotary pump on my Rocket R Cinquantotto started making a loud vibrating noise that was affecting my morning espresso ritual in Ballantyne. I reached out for coffee repair help and they were able to fit me into their schedule much faster than I expected. The technician diagnosed a worn pump motor and replaced it with a genuine Rocket part immediately. He also checked the group head and replaced the gasket with a high-quality silicone version which makes engaging the portafilter much smoother. It is refreshing to deal with a professional who treats home espresso machines with the same respect as commercial ones. If you own a Rocket R Cinquantotto and need maintenance this is definitely the place to go. My espresso machine is back to being silent and powerful.

I brought my Rocket R Cinquantotto in from Concord for a two-year professional maintenance check-up and a general internal cleaning. The technician was very knowledgeable and discovered that my steam boiler was starting to show signs of scale buildup because of my local water quality. He performed a full professional descaling and also rebuilt the E61 group head with new internal valves and springs. The turnaround for the coffee machine repair was fast and the communication throughout the process was excellent. It is great to have such a skilled technician nearby who can handle the complexity of the Rocket R Cinquantotto. I highly recommend their services to any espresso enthusiast looking for top-tier maintenance for their equipment.
