Our La Marzocco GB5 S started making a strange buzzing noise from the solenoid valve every time we engaged group one in Pineville. We reached out for professional coffee repair and the technician was able to pinpoint the issue as a scale-clogged valve that was struggling to open. He cleaned the valve and performed a full system maintenance check to ensure no other components were being affected by our local water quality. He was very professional and gave us some great recommendations on improving our water filtration system for the shop to prevent future clogs. The service was fast and our GB5 S is now whisper quiet and performing perfectly again. A fantastic choice.
