What does the noise I can hear during the brewing cycle mean on my TrueBrew?

There are 3 main technical phases in each coffee cycle: grinding, internal movement of the brewing unit to prepare the infusion and the infusion itself. That differs from every standard drip coffee machine available on the market as True Brew is automatically grinding and dosing the coffee according to the size and style you selected. Grinding phase and each different movement of the internal mechanism can create some possible noise that is absolutely normal and natural for the correct execution of the brewing process
