How to descale a La Marzocco Linea Mini or Micra

This guide covers descaling for La Marzocco's home range — Linea Mini, Linea Micra, and the GS3 for the well-resourced. LM machines are dual-boiler saturated-group machines using stainless brew boilers and a specific water-treatment philosophy that LM publishes itself. The article walks through the LM-recommended approach using Cafetto descaler (the safe, biodegradable choice that won't damage the dual-boiler architecture or the saturated group), how to handle the steam boiler separately from the brew boiler, and why LM owners should be more disciplined about water filtering than other brands — the saturated group is more sensitive to scale buildup than an E61 group because the boiler-to-group thermal connection is direct rather than indirect. The article also covers when an LM has crossed the line where home descaling isn't enough and the boiler needs a workshop strip-down (which Coffee Parts can arrange through its national service network). Cross-sells include Cafetto descaler, LM in-tank water filter cartridges, the LM steam tip range, Coffee Parts silicone gaskets where applicable, and BWT plumb-in filter kits for owners ready to graduate from tank-fed to fully plumbed setups.
