Cleaning & Descaling Guidelines
- Descaling frequency depends on water hardness and usage volume
- Hard water environments require more frequent descaling
- Only approved cleaning agents should be used to avoid damage
- Neglecting descaling can reduce heating efficiency and pressure stability
Troubleshooting by Coffee Machine Type
- **Espresso Machines:** Pressure inconsistency and scale buildup may occur without regular cleaning.
- **Capsule Coffee Machines:** Capsule misalignment or blocked piercing needles can affect extraction.
- **Bean-to-Cup Machines:** Grinder wear and milk system blockage require frequent inspection.
- **Commercial Brewers:** High-volume use accelerates wear on pumps, valves, and heating elements.
Preventive Maintenance Tips
- Monitor water quality and replace filters regularly
- Schedule professional servicing at fixed intervals
- Maintain cleaning and service logs
- Train staff on basic operational checks
- Avoid operating machines beyond rated capacity
