Limescale buildup in the coffee machine leads to longer brewing times and poorer heat transfer. This is often followed by reduced water dispensing, which together results in lower quality and an altered taste of your coffee.
Limescale builds up in the machine over time and can eventually clog the fine pipes. Limescale also promotes corrosion of the materials in the coffee machine. Both can damage the machine.
Limescale buildup leads to higher energy consumption in your coffee machine and is therefore harmful to the environment.
