Inside the machine

From boiler to cup

The boiler heats one supply of water. The steam knob draws from the space above it, and the brew group draws from below the surface. The lever changes what happens next.

Follow the water

Lift the lever and the piston rises past an inlet in the group. Boiler pressure pushes water up the pickup tube and into the chamber. On the way down, the piston passes the inlet again and traps water beneath it.

Water Piston Coffee Steam path

A pressure switch cycles the heater as the boiler loses and regains pressure. A separate thermostat cuts heat if the boiler gets too hot, and a relief valve can vent excess pressure.

The drawing simplifies the passages. See La Pavoni’s manual, sections 4.5 to 4.9, and the group and boiler fittings drawing.

Why the handle is so long

A force farther from the pivot has more leverage. At the other end of the lever, the piston rod moves through a shorter distance and receives a larger force.

ForceWater under the piston

Idealised lever with a 40 mm piston arm and 50 mm piston diameter. Piston force equals hand force times the ratio of the arms. Pressure equals piston force divided by piston area. The real linkage changes angle through the stroke. Flow and pressure in the coffee also depend on the puck.

Take the group apart

The piston seals against the liner, the shower screen spreads water over the puck, and a separate gasket seals the rim of the basket. Pull the layers apart to see where each piece sits.

Select a layer to read what it does and find its TAV2 callout.

The layers show how the assembly fits together. For service and exact hardware, use the Professional exploded drawing or the Lusso exploded drawing.

Parts index

From cap to feet

Look up a part by what it does, its name, its drawing callout or its manufacturer code. Callout numbers restart on each sheet.

Open the Professional drawing

The index follows drawings 2880078 and 2880081, dated August and September 2025. Check the data plate, market voltage and revision before ordering. The original sheets also include a wiring diagram for service technicians.
