While your home machine doesn’t need the maintenance of a professional espresso maker, there is some recommended daily maintenance. - Remove the grounds from the filter basket after every shot. Rinse and wipe it out before making a new shot. - Dry the portafilter before loading it with more grounds or before putting the machine away for the day. - Attach the filter basket to the group (group heads are the portion of the espresso machine that attach to the portafilter), and run fresh water through it to rinse out any leftover coffee grounds. Espresso machines need deep cleanings as often as once a week if you’re using them daily. Read through the owner’s manual to learn how and which components to clean in this deeper maintenance process.
