Proper machine maintenance is critical to proper machine functionality. Most machine failures are caused by a lack of cleaning and maintenance. This is vital, as many manufacturer warranties do not cover cleaning/maintenance related breakdowns. To avoid this, it is imperative to keep a regular maintenance schedule. Listed below is a suggested maintenance rundown for most semi-automatic espresso machines:
Descaling
Descaling the machine should be done on a bimonthly basis using the product recommended by the manufacturer. Descaling is still required even if reverse osmosis, distilled, or zero water is being used. Refer to your machine manual for specific instructions for this unit.
Grouphead Cleaning
The grouphead should be taken apart on a monthly basis to remove scale buildup, remove coffee residues, and improve shot flavor.
Steam Wand Cleaning
Steam wands, steam tips, and nozzle attachments should be cleaned daily after the machine is finished being used for the day. Milk residues quickly build up on steam wands and frothing nozzles, so it is important to keep these clean to prevent blockages from forming.
Replacing Group Gasket
The group gasket will typically need to be replaced approximately every six months to a year. It is not necessary to replace the gasket until leaking at the grouphead occurs, but it is good to have a gasket on hand since the machine cannot be used with a broken gasket. Instructions can be found on page 25 of your user manual.
