When it comes to coffee, a lot things are subjective. Well, almost everything except the fact that you cannot do without regular espresso maintenance. Every time you pull a delicious shot of espresso your machine accrues layers of oils, milk proteins, mineral deposits and espresso debris. This should be cleaned. So, you want to know how to maintain espresso makers? Try my daily and 3-month espresso makermaintenance routine.

Daily espresso maintenance

It’s the end of the day and you have enjoyed a cup (or two) of your favorite brew. Before you retire to bed, back flush the machine. What does back flushing mean? Here is the breakdown:
• Run the grouphead then scrub off all loose coffee with a machine brush.
• Put a spoon of detergent in your blind filter. Insert it into the group.
• Run the machine on for ten seconds then off for another ten seconds. Repeat this 4 times.
• Leave the blind filter in the group for about 5 minutes. This will be the opportune time to clean steam wands, portafilters or even rub it into a shine. Don’t be tempted to skip this step. These 5 minutes allow the detergent to loosen and ‘eat off’ the debris; something that not even hot water can do.

Every 3 months

Your espresso machine needs a minor service after every 3 months. Don’t worry. This won’t take you long. You will need to:

• Replace the group gaskets.
• Replace the shower screens (here I’d recommend that you upgrade to an IMS or VST screen if you don’t have them)
• Test temperature and group flow rates as well as the switches.
• Check group-head and boiler water quality.

Follow this routine and your espresso machine will run smoothly. In addition to this, it may be a good idea to call in a professional to check it for you. Nothing should stop you from enjoying good coffee.
