Maintenance Tips

• Daily sprayhead cleaning (critical): Remove and clean sprayhead holes to maintain even water distribution. This ensures consistent extraction and prevents weak or over-extracted coffee.
• Deliming routine (1–3 months): Use a deliming spring in the sprayhead tube to remove mineral scale buildup that slows flow, reduces brew volume accuracy, and strains the heating system.
• Clean brew funnel daily: Wash with mild detergent to remove coffee oils that cause bitterness, odor, and slow drainage.
• Wipe exterior & warmers daily: Keep warming plates, splash areas, and control panel clean to prevent residue buildup and overheating issues.
• Flush hot water faucet weekly: Run water through the faucet to prevent mineral blockage and maintain steady flow for tea or hot water use.
• Descale internal tank periodically: Hard-water scale reduces heating efficiency, increases recovery time, and causes inconsistent brew temperature.
• Check water supply (20–90 PSI): Stable pressure is essential for correct batch volume and consistent performance in high-volume brewing.
• Inspect warmers and auto shut-off: Ensure warming plates cycle correctly and shut off when idle to prevent energy waste and overheating wear.
• Keep brewer level: Ensures accurate decanter fill levels and even distribution across brew cycles.
• Use energy-saver mode during idle times: Reduces tank temperature stress and extends heating element lifespan.
