Rocket Espresso Appartamento Espresso Machine

Before proceeding, check the box and machine for any signs of damage or tampering. If significant damage is found, stop and contact Seattle Coffee Gear at 866-372-4734 before continuing.

Placement and Installation

Place the machine on a flat, dry, stable surface. The base should be approximately 100–105 cm above the floor. Leave at least 10 cm of clearance on each side and behind the machine for ventilation. Do not install near heat sources, outdoors, or in damp rooms. Operating temperature must be between 5°C and 36°C.

Filling the Water Tank

Lift the water tank chamber cover and fill the tank with clean, filtered water up to the MAX line (approximately 1.9 L). Rocket recommends placing a softener bag in the tank. Water hardness should be between 4–7 °f (French) / 2–4 °d (German). Do not use distilled water. Reposition the cover firmly after filling.

First Start-Up

1. Make sure the coffee dispensing lever is in the vertical (OFF) position.
2. Turn the main switch from O to I to power on.
   
   Appartamento: the indicator light glows steady green.
   
3. Open the steam knob — you'll hear the pump begin filling the boiler
4. When the pump stops, close the steam knob. Boiler heating begins.
5. Wait for the boiler pressure gauge to reach approximately 1 bar.
6. Open the steam knob for 5 seconds to release any vacuum inside the boiler, then close it again. This step is critical — skipping it can cause milk to be drawn back into the boiler.
7. Wait for the gauge to return to 1 bar.
8. Fully raise the coffee dispensing lever and drain one cup of hot water from the group head. This purge step is only required on first use.
9. Lower the lever to stop flow.

The machine is now ready. Allow 15–18 minutes of warm-up time before pulling your first shot — a fully heated group head and portafilter make a significant difference in espresso quality.

Installing the Portafilter

Insert the portafilter into the group head and rotate the handle left to right until it sits firmly at 90 degrees from the front of the machine. Leave the portafilter locked in the group head whenever the machine is not in use — this keeps it heated and prevents the group head gasket from drying out prematurely.

Pulling Your First Shot

1. Select the single or double portafilter basket.
2. Fill with ground coffee, tamp evenly, and remove any grounds from the basket rim.
3. Lock the portafilter into the group head and place your cup(s) under the spout.
4. Raise the coffee dispensing lever to start extraction. Lower it to stop.
5. Maximum extraction time is 100 seconds — the machine stops automatically after this.
6. Remove, empty, and rinse the portafilter, then re-lock it in the group head.

It is recommended to run one water-only pull through a new portafilter before your first actual shot to clear any manufacturing residues.

Brush the brew head filter daily. Every week, after backflushing, add a small amount of espresso cleaning detergent to the blind basket. Dissolve the detergent in hot water and insert the portafilter into the unit head. Open and close the unit dispensing for about 10 seconds. Repeat several times. Backflushing should be performed weekly under most use cases. For heavier use cases, 6+ drinks a day, use detergent when backflushing more often, around every 20 drinks.

Machine Requires Cooling Flush After Idle

The Appartamento is a heat exchanger machine. After sitting idle at temperature, the water in the group head can overshoot brew temperature. Run a short cooling flush (2–4 seconds of water through the group) before pulling your shot when the machine has been idle for 10+ minutes.

Steam Pressure Low

Allow additional heat-up time after startup — the Appartamento needs 20–30 minutes to fully stabilize. If steam pressure is consistently weak, check that the steam knob is fully closed when not steaming.

Shot Channeling or Uneven Extraction

Check grind distribution and tamping technique. Ensure the portafilter basket is clean and the shower screen is free of buildup. The Appartamento's dual pre-infusion system helps, but good technique is essential.

Water Leaking from Group Head

The group head gasket may be worn. The E61 group gasket is a standard part — replacement is straightforward. Contact SCG for part sourcing.
