Siemens TZ800Z3 Cleaning and Descaling Cartridge Set, Black

The Siemens TZ800Z3 Calc’nClean maintenance set is designed for the EQ900 Plus series of fully automatic espresso machines. It streamlines maintenance by using dedicated cartridges for cleaning and descaling. One cartridge removes coffee oils and residue from the internal brewing unit, while the other prevents limescale buildup in the heating system. Users place the cartridges into the machine to run the Calc’nClean program. This replaces the need for manual dosing with tablets or liquid descalers, ensuring the appliance is cleaned according to the manufacturer’s specifications.

These cartridges are compatible only with Siemens EQ900 Plus machines equipped with an automated cartridge interface. Sensors inside the machine detect the cartridges, which then interact directly with the automated cleaning and descaling systems. Using the set regularly keeps the brewing circuits clean and prevents the buildup of deposits that can affect coffee flavour. Because the process is software-controlled, the machine uses the exact amount of cleaning agent required, removing the need for manual measurement and helping to maintain consistent performance.
