La Marzocco Linea Mini maintenance kit, major service

La Marzocco maintenance kit for the major service on a Linea Mini

Many years ago, I was looking for a complete maintenance kit for a major service on a Linea Mini. Unfortunately, then and now, I couldn't find one that included all the parts that should be replaced according to La Marzocco and my own experience over the years. I also have a “budget version” with a reduced range of parts and also a maintenance kit for the minor service is available in the shop.

This maintenance kit is for the "old" version of the Linea Mini. This can be identified by the serial number on the nameplate, which begins with "LM." This version also lacks a display on the front.

The kit contains all wear parts that need to be replaced during a major service on a Linea Mini. Depending on the type and intensity of use of the machine, the major service should be performed after approximately one year for commercial use and after three to five years for private use.

Over time, the components installed in machines have changed slightly. Therefore, different maintenance kit options are available, which must be selected according to the machine's configuration. Before purchasing, it's important to check which version is required.

Cool Touch steam wand:

Since 2021, all machines have been equipped with a Cool-Touch steam lance. Whether a Cool-Touch steam lance or the older version without Cool-Touch is installed can be identified by the rubber coating on the older version.

If an old steam lance without Cool-Touch is installed, this can be switched to the latest version from the Linea Mini R. The replacement is very simple, as only a cotter pin needs to be removed and then the lance can be replaced.

Portafilter seal:
– La Marzocco portafilter seal "reduced force" (H.3.018) -> Scope of delivery Linea Micra & Linea Mini R in conjunction with the combo portafilter (A.5.186) and bottomless portafilter (L111/X.01)
– La Marzocco portafilter seal (H.3.004) -> Scope of delivery Linea Mini & GS3 in conjunction with the Stainless steel portafilter with 2 spouts (L111/2NAC) and Stainless steel portafilter with 1 spout (L111/1AC)
– La Marzocco Silicone portafilter seal (H.3.007) -> Scope of delivery Linea Mini & GS3 in conjunction with the Stainless steel portafilter with 2 spouts (L111/2NAC) and Stainless steel portafilter with 1 spout (L111/1AC)

shower screen:
– La Marzocco Shower screen (F.3.040.01) -> This is the shower screen included with the machine
– IMS Competition Nanotech shower screen for La Marzocco (MA200NT) -> This is an “upgrade” shower screen that I personally like to use.

Vacuum valve on the steam boiler:
There are also different versions of the vacuum valve on the steam boiler. Since model year 2021, only the new SMA vacuum valve (B.2.029.01) If the old Vacuum valve” (L192.03) is mounted, this can either be overhauled analogously with the corresponding wear set, or with the new SMA vacuum valve (B.2.029.01) should also be replaced.

All parts included are original La Marzocco spare parts.
