Coffee is big business in Australia. McCrindle reports that three in four Australians (75%) enjoy at least one cup of coffee per day, and of those, 28% have three or more cups per day. More than four in five Australians (84%) spend money on coffee in an average week and more than one in four (27%) confessed that they can’t survive one day without it!

The bottom line is that there is potential to sell a lot of coffee, and to make sure you keep your customers coming back for more, consistent taste and quality are of paramount importance.

  • Coffee machines are expensive pieces of equipment, so you want it to last as long as possible. Maintaining your machine should make it last longer, ensure that it runs smoothly, and you may not need to service it as often. It should also reduce the likelihood of major problems and make servicing easier.

    Stale coffee left in your machine will affect the flavour of your fresh coffee. If you clean your machine regularly, your coffee will taste better. Clearing out the build-up of coffee oils reduces the bitterness of the coffee.

It is recommended that you clean your machine on a daily-basis. If you don’t clean your machine regularly, it will degrade from a build-up of oil and mineral residues.

What are the components I need to clean?

  1. Portafilter – filter basket with a handle that holds the coffee grounds and locks into the group head.
  2. Group head – permanent metal attachment at the front of the machine to which the portafilter attaches, it directs hot water out of the machine into the portafilter’s filter basket.
  3. Shower screen – sits inside the group head and disperses the water to ensure it spreads evenly over the filter basket, which is holding the coffee grounds.

Steam wand – used to heat and froth milk for use in various coffee drinks

  1. Soft cloth
  2. Group head brush
  3. Backflush detergent

With special care and attention as you are working with extremely hot water.

Step 1: Clean the portafilters

  1. Place half a scoop of detergent in each filter basket.
  2. Insert portafilters into the group head and dispense water from the group for 30 seconds.
  3. Remove portafilters and rinse using the water tap on the espresso machine to remove external oil and soap.
  4. Remove the basket and wipe it clean, ensuring that both the group handle and the basket are free of oil.
  5. Use a soft cloth to wipe the group head seals (warning: very hot).

Now move onto cleaning the internal parts of the machine by backflushing, which will remove any oils or grime which build up in the internal piping of the group heads.

Step 2: Backflush

  1. Place half a scoop of detergent in each blind filter basket.
  2. Insert portafilters into the group head and lock them securely.
  3. Activate the group heads for 10 seconds, and then deactivate for 10 seconds.
  4. Cycle the group heads on and off 3 times.
  5. Remove the blind portafilters and dispense water from the group head for 10 seconds.
  6. Rinse out the blind portafilters.
  7. Insert clean portafilters into the group heads and repeat the backflush process without chemicals to rinse the insides of the machine.

Step 3: Clean the group heads

  1. Remove the shower screen, rinse under running water and wipe dry. If you need to unscrew the shower screen, make sure you put the screws somewhere safe, so you don’t lose them.
  2. Use a soft cloth to wipe the group head seals to remove any ground coffee (warning: very hot).
  3. Reattach the shower screen to the group heads (if applicable, screw in until just tight).

Step 4: Clean the steam wands

After steaming milk, wipe the wands down with a damp cloth and open the steam tap to let a small amount of steam out to prevent milk from drying on the inside of the steam nozzle or the exterior of the wand.

Step 5: Clean the drip tray

The drip tray needs to be detached, emptied, washed, drained and reattached.
