Gaggia Classic/cleaning and maintenance
From Whole Latte Love Support Library
Descaling should be done, at minimum, on a bimonthly basis using the product recommended by the manufacturer. Watch our video to see the correct procedure for descaling your machine.
The grouphead should be taken apart on a monthly basis to remove scale buildup, remove coffee residues, and improve shot flavor.
Backflushing is the process used to clean out the shower screen, brew group, and three-way valve. The cleaner will remove the old coffee oils and deposits, as well as prevent coffee from building up on the shower screen.
For deep cleaning and maintenance of the Classic boiler, watch our video on how to perform a full tear-down. Get the job done right in thirty minutes.
Steam Wand Cleaning
Steam wands and nozzle attachments should be cleaned daily once the machine is finished 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 about 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.
Recommended Cleaning Products
The compatible descaling products for this machine are either Gaggia Decalcifier or Durgol Swiss Espresso Descaler. The best product for cleaning grouphead components and filter baskets is a backflushing powder like Urnex Cafiza.
