Piston espresso machine losing pressure mid-shot, piston sticking, or producing no pre-infusion? Piston machines create espresso pressure by hand — precision seals and smooth cylinder bores are essential. Our Westlands workshop rebuilds piston groups to like-new condition.

Piston Espresso Faults We Diagnose
- Pressure drops quickly during pull — worn piston cup seal no longer holding pressure against the cylinder wall.
- Piston sticking on downstroke — corroded or scored cylinder bore, or swollen piston seal from chemical damage.
- No pre-infusion pressure — blocked pre-infusion chamber or missing check valve in the piston assembly.
- Water leaking past the piston upward — upper cylinder O-ring failure allowing back-flow into the spring chamber.
- Handle cracked at base — stress fracture from repeated pulls; sourcing or fabricating replacement handles.
- Boiler not reaching pressure — scaled heating element or failed pressurestat.
Our Piston Repair Services
We hone cylinders to remove scoring, fit new cup seals, replace O-ring kits, and test pre-infusion pressure with a calibrated gauge. Food-safe silicone grease used on all rebuilt pistons.
