Before first use: tank or mains water

  1. Run from the tank with fresh, soft water, or plumb into the water line. Plumbing should be done by a qualified technician (we can do this); Quick Mill specifies 4–8 bar inlet pressure and a reducer above that.
  2. Switch on with the group lever down and allow about 12 minutes to heat.
  3. Run water through the group and purge the steam wand.

Making espresso

  1. Set brew temperature on the PID.
  2. Flush, dose, tamp and lock in, then lift the lever to brew.
  3. Dial in with grind size. Brew pressure on the rotary pump is adjustable – ask us if you want it changed.

Steaming milk and hot water

  1. Purge the steam wand into the drip tray, put the tip just under the surface of cold milk and open the steam tap. Lower the tip to heat once textured, and close the tap before lifting the jug away.
  2. Wipe the anti-burn wand with a damp cloth and purge it straight away.
  3. Use the hot water tap for tea or warming cups (where fitted) – the water is very hot.

Daily cleaning (2 minutes)

  1. With the machine hot, take the coffee basket out of the portafilter and fit the blind filter (the basket with no holes) supplied with your machine.
  2. Lock the portafilter into the group and run the pump for about 10–15 seconds, then stop. Repeat several times until the water runs clear – Quick Mill suggests 10–15 short runs. This is a water-only backflush, no cleaner needed day to day.
  3. Brush the shower screen and group gasket with a group head brush and wipe away any visible coffee, without taking parts apart.
  4. Rinse the portafilter and baskets in warm water and wipe them dry.
  5. Wipe the steam wand with a damp cloth straight after each use and give it a short purge to clear milk from the tip.
  6. Empty and rinse the drip tray before it gets full, and keep the water tank clean and filled with fresh water.

Every 2–3 weeks: cleaner backflush

For home use, a backflush with espresso machine cleaner every 2–3 weeks keeps the group fresh. Quick Mill’s manual also suggests brushing the group gasket at least once a week and soaking the baskets and portafilter head in very hot water from time to time to lift coffee oils.

  1. Heat the machine up fully and brush the shower screen and gasket.
  2. Fit the blind filter and add a small scoop (about 3–5 g, or the amount on the pack) of espresso machine cleaner such as Cafetto Espresso Cleaner or Cafetto EVO.
  3. Lock the portafilter in and run the pump for about 10 seconds, then stop and let the cleaner soak for 10–20 seconds. Repeat several times.
  4. Remove the portafilter, rinse the blind filter and portafilter, then backflush again with water only until no cleaner foam or smell remains.
  5. Run some fresh water through the group without the portafilter, refit your normal basket and pull one shot to discard.
  6. While the cleaner is out, you can soak the metal portafilter head and baskets (not the handle) in hot water with a little cleaner for 10 minutes, then rinse well.

Water and servicing

  • Descaling: leave this to us. Your machine should only be descaled by a qualified technician as part of its service. Call 1300 357 575 to book.
  • Quick Mill says to run the machine on soft, clean drinking water, and to use a water softener where your water is hard. Very pure water (such as distilled) can stop the level sensors working, so use filtered water.
  • Book a service every 12 months for home use, or every 6 months for cafés and busy commercial sites, so seals, gaskets and valves are checked before they wear.
