Daily Cleaning

Wipe and purge the steam wand after each use to prevent milk buildup, rinse portafilters and filter baskets, clean the drip tray, and backflush the group head to remove coffee oils and residue.

Weekly Maintenance

Soak portafilters, baskets, and shower screens in an approved cleaning solution, inspect group head gaskets and screens, and perform a deeper backflush to keep internal components clean.

Long-Term Care

Maintain proper water filtration to prevent scale buildup and descale the machine as needed based on water quality and usage to ensure long-lasting performance and consistent espresso quality.

For this single-boiler espresso machine, we recommend using a BWT Single Cartridge Water Filter or a comparable inline filtration system designed to reduce hardness, chlorine, and sediment. Regular filter replacement based on water usage and local water quality is strongly advised to extend the life of the machine and preserve flavor clarity.

• Voltage: 220-240 VAC
• Wattage: 5210 - 5350W
• Electrical: Requires a 230V circuit (dedicated circuit strongly recommended)

Summary: This machine runs on a 230V power supply, making it ideal for commercial cafés, high-volume service, and serious espresso setups where stronger electrical capacity is available. With a compatible-watt draw, it should be connected to a dedicated circuit to ensure stable performance—especially if you’re running other equipment nearby (grinder, fridge, hot water tower). This setup is best for fixed locations with proper electrical infrastructure, rather than most mobile coffee carts where 230V isn’t always available.
