Question

My machine is making unusual noises.

Answer

An espresso machine goes through more steps when brewing coffee than a drip-filter coffeemaker. It grinds beans, its brew group moves, the pressure is compensated during brewing and frothing milk: this creates not only a different taste of coffee but also produces other sounds.   

Small changes in the settings can already affect the sounds produced. If unusual sounds occur:

  • Change the coffee grind and coffee length and see if this works. 
    You can find the instructions for; How to change the coffee grind setting and the coffee length, under 'Related Articles' below.  

  • A stuck brew group or scale deposits in the water circuit can also cause unusual sounds. 
    Clean and lubricate the brew group. If this does not reduce the unusual noise, descale the machine. You can find the instructions for cleaning and descaling under 'Related Articles' below. 


Expert’s tip:

"If there are foreign particles in the bean container, e.g .pieces of wood, small pebbles or something similar, the grinder can also produce unusually loud noises. Clean the grinder to remove foreign particles. Empty the coffee bean hopper and use a vacuum cleaner to remove any residues from the grinder. Never pour water into the coffee grinder."
