Maintenance Tips

• Daily sprayhead cleaning (critical): Remove and clean sprayhead holes so all outlets stay open. A clear spray pattern ensures even saturation of coffee grounds and consistent brew strength.
• Deliming routine (daily in hard water areas): With the sprayhead removed, insert the deliming spring into the spray tube and work it back and forth to break scale buildup that restricts flow and causes weak or uneven brews.
• Flush after deliming: Run a brew cycle with an empty funnel to flush loosened mineral deposits and keep internal water paths clean.
• Clean brew funnel daily: Wash with mild detergent to remove coffee oils that cause bitter taste and slow drainage.
• Wipe exterior surfaces daily: Use a damp cloth and non-abrasive cleaner; avoid pressure washing or harsh chemicals near switches.
• Check brew temperature consistency: Low temperature (below ~195°F) usually indicates scale buildup or heater inefficiency and requires descaling.
• Inspect water supply (20–90 PSI): Stable pressure ensures correct batch volume and prevents under/over-brewing.
• Descale regularly (1–3 months): Prevents mineral buildup in tanks and spray system, maintaining speed, volume accuracy, and flavor quality.
• Keep brewer level: Ensures proper siphoning and accurate batch delivery.
• Preventive maintenance: Periodically inspect seals, sprayheads, and tubing to avoid leaks and downtime in high-volume use.
