Coffee Technician Program Water & PM

• 80% of coffee machine issues come from poor water quality or neglected maintenance.
• Incorrect water treatment can reduce boiler efficiency by up to 25%.
• Scaling increases energy consumption and can destroy heating elements and valves.
• Every manufacturer (La Marzocco, Victoria Arduino, Rancilio, etc.) has strict water spec requirements to maintain warranty.

• Understanding hardness, alkalinity, chlorides, TDS, pH and how they affect metals and espresso flavour.
• How different filter types work: ion exchange, bypass, carbon blocks, magnesium filters, RO systems.
• How to design a correct filtration system for cafés using formulas, testing, and risk assessment.
• Preventive maintenance best-practice: boilers, valves, solenoids, pumps, gaskets, group assemblies.
• Hands-on diagnostics: identifying scaling, corrosion, electrolysis damage, blocked jets, leaking valves.

• How to test water on-site (hardness, alkalinity, chloride, pH).
• How to calculate filter capacity and when to replace filters.
• How to recognise early signs of failure: pump cavitation, steam boiler over-pressure, blocked flowmeters, vacuum valve failures.
• Correct lubrication, cleaning agents, descaling agents, and safety procedures.
• How to perform full PMs on commercial espresso machines using industry-standard checklists.

• Coffee technicians
• Baristas & café owners
• Roastery and wholesale support teams
• Anyone wanting to protect machines and improve espresso consistency
