ECM Classika PID User Guide & Cleaning

← All How guides

The Classika PID is a compact single-boiler machine: you brew first, then switch to steam. These steps follow ECM’s Classika PID user manual.

Which models this covers: For the ECM Classika PID (sold by CMB as the Classika II with PID, with or without flow control). The single-boiler workflow is the same for both options.

Before first use and daily start-up

  1. Fill the tank with fresh, soft water. Check the pump/hot water and steam switches are down and the steam/hot water valve is closed.
  2. Switch on. If the boiler is cold the display shows UP and Fast Heat Up starts; heating takes about 10 minutes.
  3. When the display shows FLU, put a tall cup under the portafilter and run a flush until it shows rdY/Go. You are ready to brew.
  4. Leave the portafilter in the group while heating so it stays warm.

Making espresso

  1. Dose and tamp, lock in the portafilter and lift the group lever to brew. Lower it to stop.
  2. The PID is set to 93 °C for coffee from the factory; you can change it on the display (see ECM’s manual).
  3. Dial in with grind size. Brew pressure can be set between about 8.5 and 12 bar on the expansion valve – ask us if you would like it changed.

Steaming milk and hot water

  1. Brew your coffee first. Then flick the steam switch up – the heating lamp comes on and the display shows the steam temperature.
  2. Open the steam valve for about 5 seconds, twice, 20 seconds apart, and wait for the heating lamp to go out – this gives drier steam.
  3. Purge the steam wand into the drip tray, then put the tip just under the surface of cold milk and open the steam valve. Lower the tip to heat once the milk is textured. Close the valve before lifting the jug away.
  4. Release a little steam into the drip tray afterwards to keep the steam holes clear, and wipe the wand with a damp cloth straight away.
  5. Draw hot water from the hot water valve into a cup with a heat-insulated handle – it is very hot.

After steaming: refill the boiler

  1. Switch the steam function off.
  2. Open the steam/hot water valve slightly and flick the pump/hot water switch up. The pump refills the boiler while hot water and steam run into a large container.
  3. Close the valve and switch the pump/hot water switch off. This also brings the boiler back to brewing temperature for your next coffee.

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 seconds, then stop. Water and coffee oils flow back out through the group into the drip tray. Repeat 4–5 times until the water runs clear. 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. ECM’s manuals suggest a cleaner backflush after roughly 90–140 shots, and note that using detergent too often strips lubrication from the group’s moving parts – so every 2–3 weeks is plenty at home, with water-only backflushes in between. You can set the CLn reminder on the PID display to prompt you.

  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.
  • ECM recommends water with a hardness of no more than 4 °dH. Use a water filter or softener cartridge where your water is harder.
  • Depending on use, refresh the boiler water every 1–2 weeks (about 0.8 L) by drawing hot water from the hot water valve.
  • 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.
