How to descale a Lelit espresso machine (Mara X, Bianca, Elizabeth)

This guide covers descaling for Lelit's home range — Mara X, Bianca, Elizabeth, and the Anna and Glenda entry models. Lelit's lineup mixes heat-exchanger architecture (Mara X), dual-boiler (Bianca, Elizabeth), and single-boiler (Anna, Glenda), which means descaling procedure varies meaningfully across the range. The article walks through Cafetto descaler dosage and process for each Lelit architecture, with model-specific notes: the Bianca's flow control paddle needs to be bypassed during descaling (never draw descaler through the paddle), the Mara X's HX setup means the steam circuit comes along for the ride automatically, and the Elizabeth dual-boiler needs the brew and steam boilers handled separately. Lelit's customer base in Australia has grown rapidly over recent years and Coffee Parts services more Lelit machines now than ever — the brand's parts availability and workshop familiarity is strong. The article addresses descaling frequency for Lelit's commonly Australian-water-affected models, when to escalate to a workshop strip-down, and which Lelit-specific parts are worth keeping in the kitchen drawer. Cross-sells include Cafetto descaler, Lelit-specific gaskets and OEM parts, Coffee Parts silicone gaskets where dimensionally compatible, and BWT in-tank filter cartridges sized for the Lelit reservoirs.
