Maintenance Tips

• Clean brew funnels and sprayhead daily to prevent coffee oil buildup and ensure even extraction from the Peak Extraction™ sprayhead system.
• Wipe external stainless steel surfaces daily with a soft cloth and mild detergent—avoid abrasives or pressure washing to protect the finish and electronics.
• Run regular hot-water flush cycles to clear residual coffee oils from internal lines and maintain consistent brew quality.
• Descale the internal tank periodically (more frequently in hard-water areas) to prevent lime scale and protect heating performance.
• Inspect sprayhead holes and clean them to prevent clogging and ensure uniform water distribution across the coffee bed.
• Sanitize brew funnels, decanters/servers, and all coffee-contact parts daily to meet food safety standards.
• Check funnel lock mechanism and ensure it operates smoothly to prevent premature removal during brewing cycles.
• Inspect water inlet lines and fittings regularly for leaks or scale buildup that can affect flow rate and brew consistency.
• Keep ventilation areas clear and ensure the unit is installed on a level, stable surface to maintain proper thermal performance.
• Follow preventive maintenance every ~6 months, including internal inspection, tank draining, and component cleaning for long-term reliability.
