Detailed Description

The Strada X 1 Group Espresso Machine has a stainless-steel coffee boiler dedicated to the brewing group and a separate stainless-steel steam boiler for steam and hot-water delivery. Independent temperature and pressure control allows the brewing system and steam system to operate for their respective tasks.

Main Components

• Main switch: Turns the machine’s electrical system on or off.
• Brewing group: Receives the portafilter and directs brewing water through the coffee bed.
• Electronic brew paddle: Starts and controls water flow for espresso preparation.
• Steam wand lever: Activates steam delivery for milk texturing and other hot-drink preparation.
• Steam wand: Delivers steam from the steam boiler.
• Hot-water wand and mix valve: Provide hot water for beverages and rinsing.
• Hot-water switch: Controls hot-water dispensing.
• Group display: Shows brewing information and machine data.
• Programming jog wheel: Provides access to available machine settings and programming functions.
• Precision scale and drain-tray grate: Support beverage weighing and collect liquid during brewing and rinsing.
• Water pump: Supplies water to the boilers and develops brewing pressure. The brewing system uses a magnetic-drive gear pump, while boiler filling uses a rotary positive-displacement pump arrangement.
• USB connection: Provides a connection point for the applicable machine software or service functions.

The coffee boiler uses electronic temperature control and is designed to maintain stable brewing conditions. Brewing pressure is produced mechanically by the pump and can operate through manual or programmed pressure profiles. The steam boiler is automatically filled and heated, with pressure controlled by the machine’s temperature and pressure systems.

Water Quality and Supply

Use potable water within the recommended quality range. The manual specifies total dissolved solids of 90–150 ppm, total hardness of 70–100 ppm, pH of 6.5–8.5, total alkalinity of 40–80 ppm, total iron no higher than 0.02 ppm, free chlorine no higher than 0.05 ppm, total chlorine no higher than 0.1 ppm, and chloride below 30 ppm. Use suitable filtration or softening equipment when the incoming water does not meet these limits.

Flush the supply line and any treatment equipment before connecting the machine. Water must be available whenever the pump operates; running the pump without water can introduce air into the coffee boiler and damage the pump.

Positioning and Initial Checks

1. Inspect the shipping package for visible damage before opening it.
2. Remove the machine from its packaging and place it on a level, stable counter.
3. Confirm that the machine, accessories, and rating-plate information are intact and appropriate for the available electrical supply.
4. Remove packaging materials from the work area and keep them away from children.
5. Make sure the drain tray, drain box, and reservoir are correctly positioned.

Reservoir Configuration

The one-group installation guide describes a water-reservoir configuration. Open the fill cover, add filtered water, slide the reservoir fully into position, and replace the drain box. Confirm that the reservoir contacts the level indicators at the rear of the machine and that the drain box is fully seated.

Electrical Connection

1. Have a qualified electrician verify grounding, circuit capacity, protective devices, and compliance with local codes.
2. For the 220–240 V version, provide a supply capable of delivering 230 V AC at 10 A.
3. Ensure the strain-relief connectors are secured before making electrical connections.
4. Connect the machine to the correctly rated supply.
5. Keep the power cable fully extended to reduce overheating risk.

First Startup and Boiler Filling

1. Open the water supply or confirm that the reservoir contains sufficient filtered water.
2. Turn the main switch to position 1. The steam boiler begins its automatic filling sequence.
3. When the steam boiler reaches its programmed water level, filling stops automatically.
4. The pump fills the coffee boiler when the machine starts. During first installation, air must be removed from the coffee boiler and group assembly.
5. Remove the group’s upper plastic cap and handle to access the bleed screw.
6. Loosen the bleed screw carefully and allow air to escape until water flows beneath the screw head.
7. Tighten the screw without excessive force to protect its sealing washer.

Initial Flushing

1. Fit a portafilter into the group and lock it in place by rotating the handle from left to right.
2. Activate the brew paddle and flush water through the group for at least two minutes.
3. Run the steam wand for at least one minute while avoiding contact with the steam and hot surfaces.
4. Open the hot-water control long enough to dispense at least one liter.
5. Allow the machine to reach operating temperature before preparing beverages.

Operation

Brewing Espresso

1. Fill the selected portafilter basket with ground coffee.
2. Tamp the coffee evenly and wipe loose grounds from the rim.
3. Lock the portafilter into the brewing group.
4. Place the cup or cups on the drain-tray scale area.
5. Move the electronic brew paddle to begin water flow.
6. Monitor the display, beverage weight, and pressure during extraction.
7. Return the paddle to its stop position when the desired extraction is complete.
8. Remove the portafilter only after brewing has stopped and pressure has released.

Steam and Hot Water

Use the steam wand lever to activate steam for milk or other hot drinks. Wipe the wand immediately after use and release a short burst of steam to clear residue from the nozzle. Use the hot-water switch and valve to dispense hot water, taking care to avoid splashing and burns.

Pressure Checks

During initial heating, coffee-boiler pressure can rise as the water expands. The expansion valve limits the coffee-boiler pressure and should prevent it from exceeding 13 bar. During brewing, the coffee-boiler pressure is normally around 9 bar, while the gauge may show a broader operating range from 0 to 12 bar.

The steam boiler is factory-set at approximately 1.4 bar. Its normal operating range is approximately 1.3–1.5 bar, although the installation guide allows operation between 1.3 and 2 bar.

Expansion Valve Adjustment

Adjustment should be performed only by qualified personnel because the valve can release very hot water.

1. Remove the left glass panel to access the expansion valve.
2. Use appropriate heat protection and identify the brass, hexagonal valve.
3. Turn the valve clockwise in small increments to increase pressure.
4. Turn it counterclockwise in small increments to decrease pressure.
5. Replace the glass panel after each adjustment and recheck the pressure during heating.

Volumetric Pump Adjustment

The volumetric pump is factory-set at approximately 3 bar. If adjustment is required, a qualified technician should remove the left glass panel, loosen the pump adjustment locknut, and use the adjustment screw while observing the pressure gauge. Clockwise rotation increases pressure; counterclockwise rotation decreases it. The adjustment should be made with the machine operating and coffee present in the portafilter.

Cleaning and Maintenance

Group Cleaning

1. Place approximately one tablespoon of espresso-machine detergent into the supplied blind filter.
2. Lock the blind filter into the portafilter and attach it to the group.
3. Turn the brew paddle on and off about ten times, using intervals of approximately ten seconds.
4. Remove the portafilter and rinse the group with a normal filter by running hot water through it several times.

Filters and Portafilters

1. Mix two or three teaspoons of machine-cleaning detergent with approximately half a liter of water in a heat-resistant container.
2. Heat the solution until boiling, then fully submerge the filters for about 30 minutes.
3. Rinse the filters thoroughly with clean water.
4. Run hot water through a group with the filters installed.
5. Prepare and discard one espresso to remove any remaining cleaning flavor.
6. Wash portafilters under hot water with a suitable brush. A neutral detergent may be used when needed.

Drain System and Exterior

• Remove and clean the drain-tray grate at least twice each week.
• Pull out and clean the drain collector and drain box, removing accumulated coffee grounds.
• Wipe stainless-steel surfaces with a soft, non-abrasive cloth in the direction of the finish.
• Clean painted, printed, plastic, and side-panel surfaces with a damp soft cloth and, when necessary, warm water with mild soap.
• Do not use alcohol, solvents, or aggressive chemicals on painted, plastic, or printed components.

Wands, Diffuser Screen, and Display

• Clean the steam wand immediately after use, then release a short burst of steam to help clear the nozzle.
• Wipe the hot-water nozzle periodically with a damp cloth.
• Remove the diffuser screen by unscrewing its diffuser screw when coffee residue builds up.
• Soak the screen and screw in a hot solution containing two or three teaspoons of cleaning detergent in approximately half a liter of water for about ten minutes.
• Rinse the parts completely, reinstall them, and flush the group several times.
• Clean the portafilter support with a non-abrasive soft cloth after using the straight-in release lever, if fitted.
• Clean the display only with a damp soft cloth or mild soapy water. Do not use alcohol or harsh chemical products.

Cleaning Schedule

• After each use: Steam wand
• Daily: Portafilters, filters, diffuser screen, and diffuser screw
• At least twice weekly: Drain grille and drain collector
• Monthly: Hot-water nozzle
• Yearly recommendation: Fully drain the steam boiler using its dedicated drain cock, with the work performed by qualified personnel

After Extended Inactivity

If the machine has been idle for more than eight hours, flush each group with water for at least two minutes, run each steam wand for at least one minute, and dispense at least one liter through the hot-water outlet before preparing beverages.

For longer storage, disconnect the machine from the water supply and electrical supply. To depressurize the steam boiler, set the machine to off using the encoder control and then press down the steam lever. Use appropriate care because steam and water may remain hot.

Troubleshooting and Corrective Guidance

• The machine does not fill: Check that the water supply or reservoir is available, the supply valve is open, and the inlet line is not blocked. If the pump has operated without water, stop the machine and have it inspected.
• Air remains in the coffee boiler after installation: Repeat the group-bleeding procedure until water flows steadily from below the bleed screw, then tighten the screw without over-tightening.
• Coffee-boiler pressure rises above the permitted limit: Stop normal operation and have the expansion valve checked and adjusted by qualified personnel. Do not handle the hot valve without suitable protection.
• Steam pressure does not reach its normal range: Confirm that the machine has sufficient water and adequate heating time. Persistent problems require authorized service.
• Water or coffee drains slowly: Clean the diffuser screen, diffuser screw, filters, portafilter, drain grille, and drain box. Remove accumulated coffee grounds.
• Steam quality or beverage flavor changes: Clean the steam nozzle immediately after use, flush the machine after extended inactivity, and verify that water treatment remains within the specified quality range.
• The machine operates incorrectly or leaks: Switch it off, disconnect the electrical supply, close the water valve, and arrange qualified service. Do not attempt to repair internal components.

Decommissioning and Disposal

1. Turn the main switch to the off position.
2. Disconnect the machine using the circuit breaker or other approved electrical isolation device.
3. Remove the power connection and disconnect the pump motor power cord.
4. Close the water supply upstream of the filter or softener.
5. Disconnect the water lines, pump connection, and reinforced drain hose.
6. Move the machine carefully, using appropriate handling equipment and avoiding crushed fingers or dropped components.
7. Send the machine to an appropriate equipment-disposal or recycling facility so its materials can be separated and recovered where possible.
