La Marzocco Coffee Machine Repairs
La Marzocco has made espresso machines in Florence since 1927, and its dual-boiler designs are still a fixture in Melbourne cafés. Our technicians repair La Marzocco machines on site, from worn gaskets and dented dispersion screens to scale lodged in the flow restrictors, so service can carry on with the minimum of fuss.
- Repaired at your café: the technician works on the La Marzocco in place, keeping it connected to water and drain.
- Quote, then work: you agree the cost first, then genuine La Marzocco parts go in under our warranty.
- Getting there: 4 to 24 hours within 30 km of Caulfield South, otherwise 24 to 48 hours.
Repair or buy new? A La Marzocco is built to be rebuilt, so gaskets, screens, valves, elements and scale damage are nearly always worth repairing. Replacement is worth weighing only when an old machine needs a whole boiler and its electronics at once, or no longer suits how busy you are. If that is where you land, have a look at the machines currently in our shop.

A brand made to be maintained
The Bambi brothers founded La Marzocco in Florence in 1927, and the company introduced ideas such as the horizontal boiler and the dual-boiler layout that many espresso machines now use. A machine like the Linea Classic AV can stay in service for a long time, provided it gets regular care. Most of the work we do on La Marzocco is wear-and-tear maintenance rather than outright failure.
Parts that wear, and how you can tell
The group gasket
If the portafilter handle has to swing further across before it stops leaking, the gasket has shrunk or hardened. La Marzocco suggests changing it every 6 to 12 months on a busy bar. Standard black rubber and orange silicone versions exist; silicone generally lasts longer.
The dispersion screen
This screen spreads water evenly over the coffee and keeps grounds away from the brew boiler. Dents, warping or a layer of old coffee oil spoil the shot, and it should also be replaced every 6 to 12 months. It is held by a small screw that should be snugged gently, because over-tightening makes it hard to remove next time.
Bayonet ring leaks
Drips around the bayonet ring can mean a dry, brittle gasket or a portafilter that is not engaging properly. Brand-new machines often feel tight at first; an older machine that suddenly leaks needs checking.
Scale in the flow restrictors
Water held at temperature and pressure without being drawn off changes chemistry and drops scale, often in the tiny flow restrictors. Shots slow or stop at one group. We clear or replace the restrictors and look at the boilers for further build-up.
Water and boiler care
Water outside La Marzocco’s specification shortens the life of elements, valves and boilers and affects the taste in the cup. Use a suitable filter, test the water from time to time, and consider draining and refilling the steam boiler every month or two so concentrated water does not sit inside.
How a visit runs
Book online or call 1300 529 505; we confirm within one business day. The technician inspects the machine on site, explains what is worn and quotes before replacing anything. Genuine parts not on hand are ordered and fitted on a follow-up visit, then the machine is tested and the work warranted.
La Marzocco FAQ
Should I switch to silicone gaskets?
Many cafés do, because silicone holds its shape longer. We can fit either and talk you through the difference.
Is a slow group always scale?
Not always. A choked screen or a grind that is too fine can do the same, so we rule those out first.
