Rocket R58 Cinquantotto User Guide & Cleaning

← All How guides

The R Cinquantotto has independently controlled brew and steam boilers (2.38 L in total), a rotary pump, an E61 group with a Cronometro shot timer and a detachable touch-screen pod for settings. These steps follow Rocket’s user manual for the R-Cinquantotto.

Which models this covers: This guide is for the R Cinquantotto (R58) dual boiler with the detachable touch-screen control pod, as sold by CMB. Rocket’s newer R58 TUNE has a different control system and is not covered here.

Before first use: water, pod and start-up

1. Choose tank or mains water. For the tank, fill with fresh filtered water and seat it firmly. Plumbing in should be done by a qualified technician – we can install it.
2. Connect the touch-screen control pod as shown in Rocket’s manual, then switch on with the group lever down.
3. Let both boilers heat fully and the E61 group come up to temperature before your first shot.
4. Run a cup of water through the group and open the steam valve briefly to clear air.

Making espresso and setting temperatures

1. Set your brew and steam boiler temperatures on the pod – each boiler is controlled separately, so you can suit brew temperature to your roast.
2. The pod also runs the automatic on/off timer, so the machine can be hot when you get up.
3. Flush, dose, tamp and lock in. Raise the lever to brew and use the Cronometro timer to track the shot.
4. Dial in with grind size. Brew pressure on the rotary pump can be adjusted externally – ask us if you want it changed.

Steaming milk and hot water

1. Purge, then texture with the cool-touch wand just under the milk surface and lower it to heat. Close the valve before removing the jug.
2. Wipe and purge the wand after every use.
3. Draw hot water from the hot water valve for tea or cup warming.

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. Rinse thoroughly with water afterwards so no cleaner is left in the group.

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.
• Prevent scale instead: always fill the tank with fresh, filtered water. Don’t use distilled water – the machine needs some minerals for its water-level sensors to work.
• 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.
