Common questions

Why does water treatment matter for coffee equipment in the UAE?
Hard water is the main cause of boiler and element failure in espresso machines and brewers. Scale builds on heating elements, insulates them and makes them overheat, and it blocks valves and jets. It also changes how coffee tastes. Filtration or softening sized to your water is part of a proper installation, and most manufacturers expect it for warranty cover.

How does the AV differ from the MP?
The AV stops shots automatically by volume; the MP uses a mechanical paddle for manual control of flow.

Is it dual boiler?
Yes, 1.5 L coffee and 3.5 L steam.

What does IoT do?
It connects to an app for settings and monitoring.

Does it need three-phase?
No, 220 V single phase.
