Maintenance Tips
- Clean brew funnels, sprayheads, and servers daily to prevent coffee oil buildup and maintain consistent high-volume extraction.
- Sanitize all coffee-contact parts (funnels, ThermoFresh servers, lids) daily using approved food-safe sanitizer to prevent contamination and flavor carryover.
- Wipe exterior stainless steel surfaces daily with a soft cloth and mild detergent; avoid abrasives or pressure washing to protect controls and finish.
- Descale internal tanks on a scheduled basis (more frequently in hard-water areas) to maintain stable brew temperature and protect heating elements under heavy load.
- Clean sprayhead holes regularly to ensure even water distribution and consistent extraction across large batch volumes (up to ~18.9 GPH).
- Flush hot water through the system daily to reduce coffee oil buildup in internal lines and preserve flavor consistency across multiple recipes.
- Inspect funnel locks and safety components to ensure secure operation during BrewWISE automated cycles and prevent accidental removal during brewing.
- Check water inlet lines and fittings regularly for leaks, scaling, or pressure issues that can affect brew consistency and recipe accuracy.
- Keep ventilation areas clear to prevent overheating during continuous commercial operation and high-output brewing cycles.
- Follow preventive maintenance kit schedules (e.g., Bunn PM kits) for seals, gaskets, and internal inspections to maximize uptime and reliability in high-volume environments.
