Sterra 8 — E15 UV Cold Water Tank ErrorUpdated 2 hours ago
The Sterra 8 features an automated ultraviolet (UV) sterilization module built directly inside the cold water reservoir. This module runs continuous cycles to keep your chilled water 100% pure, clean, and free of bacteria.
If your machine's touch panel is flashing the error code E15, the smart safety sensors have detected a fault within this cold tank sterilization system. To protect your health, the machine automatically pauses operation so that unsterilized water is never accidentally consumed.
🚨 Safety Notice: Do not attempt to open, unscrew, or troubleshoot the internal tanks of your Sterra 8 yourself. The cold water reservoir and its integrated UV components operate close to the cooling compressor and electrical grids, requiring professional tools and certified diagnostics to service safely.
