Maintenance Tips

• Daily sprayhead cleaning (critical): Remove and clean sprayhead holes to ensure even water distribution and consistent extraction. Clogged sprayheads are the main cause of weak or uneven coffee.
• Regular deliming: Use a deliming spring in the sprayhead tube to remove mineral scale buildup and maintain proper flow rate and brew volume stability.
• Clean brew funnel daily: Wash thoroughly to prevent coffee oil buildup that causes stale flavors and slow drainage.
• Wipe exterior surfaces: Clean splash zones, control panel, and base with mild detergent—avoid pressure washing or harsh chemicals.
• Monitor brew performance: Uneven spray pattern or slower brew time usually signals early scaling inside the water path.
• Descale on schedule (1–3 months): Frequency depends on water hardness; prevents heating inefficiency and temperature loss.
• Check water supply (20–90 PSI range): Stable pressure ensures correct batch volume and consistent SmartWAVE turbulence performance.
• Inspect funnel and seals: Ensure proper seating to prevent leaks and maintain full extraction efficiency.
• Run periodic water-only cycle: Flush internal lines to reduce residue buildup and keep system clean between peak service periods.
