What is the milk system tube
The milk system tube feeds milk from a container or pouch into the coffee machine's milk frother, or carries the resulting foam into the cup. It is part of the automatic milk frothing system, and its tightness and patency directly affect the quality and amount of foam.
Signs of wear
As the tube ages, its wall can harden, crack or lose flexibility, leading to air being drawn in, uneven foam, milk dripping outside the system, or complete failure of frothing. Dried milk residue inside the tube also worsens hygiene and can affect the taste of the drink.
Why timely replacement pays off
A damaged or leaking tube causes the coffee machine to draw in less milk, produce foam irregularly, or report a milk system error. Timely replacement prevents further wear of the supply components and keeps the quality of milk drinks consistent.
