Maintenance Tips

• Clean brew funnels, sprayheads, and decanters daily to remove coffee oils and maintain consistent extraction quality.
• Descale the internal tank regularly (especially in hard-water areas) to prevent lime scale buildup and maintain stable brew temperature and 3.9 GPH performance.
• Remove and clean sprayhead holes frequently to ensure even water distribution and avoid weak or uneven coffee.
• Wipe exterior stainless steel daily with a damp cloth and mild detergent; avoid abrasives to protect finish and controls.
• Sanitize all coffee-contact parts (funnels, decanters, lids) daily to maintain hygiene and prevent flavor contamination.
• Flush hot water through the system regularly to reduce internal residue and coffee oil buildup.
• Check warmer plates for spills and clean to prevent burnt residue and maintain proper heating performance.
• Inspect water inlet line (if plumbed) for leaks, scaling, or pressure issues affecting brew consistency.
• Ensure funnels are properly seated before each brew cycle to prevent overflow or spray misdirection.
• Follow preventive maintenance checks (gaskets, sprayhead alignment, internal tank inspection) to extend equipment life in commercial use.
