What TURN THE MILK FROTH ADJUSTMENT KNOB TO START CLEANING
actually means.
The Smeg milk container has a froth dial with a CLEAN setting. Once a milk drink is done, the display asks you to put the dial on its CLEAN mark, and hot water and steam then clear the tubes.

What to do when TURN THE MILK FROTH ADJUSTMENT KNOB TO START CLEANING shows on the coffee machineKind of codeMilk system
The milk system could not draw, heat or foam the milk as it should: a tube pinched or not pushed fully onto its connector, a frother or valve clogged with dried milk, a skipped cleaning cycle, or a steam valve and seal that no longer hold. Taking the milk parts apart for a rinse where the manual allows, and running the milk cleaning cycle, clears most of it; steam hissing from the wrong place or a frother that stays cold is a visit.
