Astoria has used different brewing groups, boilers, pumps, valves and electronic controls throughout its machine range. One component may be suitable for several Astoria models, while another component with a similar appearance may fit only one particular machine version.
Before ordering, check:
If no part number is visible, compare the old component carefully with the product photographs, measurements and technical information. Electrical, hydraulic and pressure-related components should never be selected solely because they look similar.
The Astoria Argenta range was produced in different machine configurations. The brewing system, controls and electrical parts can therefore vary between versions. Browse the available Astoria Argenta parts and confirm the exact machine version before ordering.
The Astoria Divina category contains components for the brewing group, boiler, pump system, valves and electrical controls. Use the dedicated Astoria Divina parts category to narrow the selection, then compare the original part number and specifications.
The Astoria Gloria is available in different control and brewing configurations, including lever-operated, manually controlled and volumetric versions. These versions do not necessarily use the same brewing-group, dosing or electrical components. View the available Astoria Gloria parts.
The Astoria Perla range also includes different machine versions. When selecting Astoria Perla parts, check whether the component is related to the brewing group, hydraulic circuit, boiler, steam system or electronic controls.
The Astoria Plus 4 You uses a more specialised heating and electronic control system than many traditional Astoria machines. Heating elements, temperature components, electronic controls and boiler parts must therefore be selected using the exact part number and machine configuration. Browse the Astoria Plus 4 You parts.
The Astoria Pratic and later Pratic versions have been produced in several configurations. Parts for the brewing group, dosing controls and electrical system may differ according to the machine version. View the dedicated Astoria Pratic parts.
The Astoria Sabrina uses volumetric controls and is available in different control-panel configurations. When selecting electronic, dosing or touch-panel components, compare the full code on the original part. Browse the available Astoria Sabrina parts.
The brewing group is exposed to heat, water pressure and mechanical wear. Common service components include portafilter gaskets, shower screens, diffusers, jets, springs, solenoid-valve seals and gaskets between the group and boiler or frame.
Water leaking around the portafilter is often associated with a worn group gasket, but it may also be caused by:
Slow or uneven water distribution may be related to the shower screen, diffuser, jet, flow restriction or group solenoid valve. Inspect the complete water path before replacing individual components.
For additional parts, view our categories for:
Before ordering a portafilter, check its diameter, ear orientation, ear thickness and locking position. A portafilter with a similar basket diameter is not necessarily suitable for an Astoria brewing group.
Astoria machines can use solenoid valves for the brewing group, automatic boiler filling and other functions within the water circuit. Complete valves, coils, valve cores and seals must be selected according to their function and technical specifications.
When replacing a solenoid valve, check:
A brewing group that does not discharge correctly may have a blocked valve, valve core or discharge pipe. This does not automatically mean that the electrical coil is defective.
Browse our category of solenoid valves for espresso machines for complete valves and related components.
Depending on the Astoria model, the hydraulic system can include a rotary pump, pump motor, flowmeters, non-return valves, expansion valves, inlet valves, level probes and various pipes and fittings.
A machine that does not fill or build pressure does not automatically require a replacement pump. The cause may also be:
When selecting a replacement pump or motor, check the rotation direction, shaft connection, flow capacity, voltage, frequency and mounting arrangement. Browse our espresso machine pumps and pump components.
Astoria espresso machines have been produced with different boiler sizes, heating-element powers and electrical configurations. The model name or number of brewing groups alone may not be sufficient to identify the correct heating element.
Before ordering a heating element, check:
If the boiler does not heat, the heating element is not necessarily defective. The pressure switch, safety thermostat, contactor, level control, wiring or power supply can also interrupt the heating circuit.
Browse our espresso machine heating elements. Check whether the element requires a separate flange gasket and replace damaged or compressed seals during installation.
Steam and hot-water valves contain wear components such as valve shafts, seals, O-rings, springs, bushes, knobs, steam tubes and complete valve bodies.
Leakage from a closed valve is often related to a worn seal or valve seat. Difficult operation may be caused by contamination, scale, a damaged shaft, a worn bush or incorrect assembly.
Astoria models may use similar valve bodies while having different shafts, knobs, steam tubes or connections. Compare the original part number, shaft length, thread and seal dimensions before ordering.
Additional components can be found in our category of steam valves and steam-valve parts.
The automatic boiler-filling system can include a level probe, electronic level regulator, inlet solenoid valve, non-return valve and water-supply components. If the boiler does not fill, overfills or fills intermittently, the complete circuit should be checked before the electronic controller is replaced.
Possible causes include:
The level probe and boiler body form part of the detection circuit. Poor electrical contact or contamination can therefore affect boiler-level detection.
Professional Astoria machines may use dosing devices, level regulators, contactors, switches, touch panels, displays and electronic control boards. These components are often specific to the machine version, supply voltage and number of brewing groups.
An electronic unit with the same housing is not necessarily interchangeable. Check:
For additional electronic components, browse our category of espresso machine dosing devices.
The boiler-pressure system can include a pressure switch, manometer, anti-vacuum valve and safety valve. These components perform different functions and should not be selected only by thread size or visual appearance.
For a pressure switch, check the electrical rating, pressure range, connection and adjustment specification. For a safety valve, the set pressure, connection, certification and application must match the requirements of the machine.
Never modify or substitute a boiler safety component without confirming the correct technical specification. Repairs involving pressure vessels, safety valves or high-voltage components should be carried out by a qualified technician.
This category contains both original Astoria components and compatible replacement parts from other manufacturers. An original component is supplied according to Astoria specifications. A compatible part is intended as an alternative to one or more stated original part numbers.
Compatible does not mean that a component fits every Astoria machine. Compatibility should be confirmed using:
A compatible gasket or mechanical component can be a suitable alternative when all relevant specifications match. Electrical, pressure-related and safety-critical parts require particularly careful verification.
Some Astoria CMA components are also used on specific Wega espresso machines. Shared components may include certain group gaskets, valve parts, boiler fittings and electrical components.
This shared use does not apply to every machine or every part. Do not assume compatibility based only on appearance or the relationship between the brands. Confirm the Astoria or Wega part number and the models stated on the product page.
The Astoria range includes traditional pump-driven espresso machines, lever-operated machines and models with volumetric or electronic controls. Components from these systems are not automatically interchangeable.
Lever-operated versions use different brewing-group components from pump-driven models. Manual and volumetric machines may share mechanical parts but use different dosing controls, flowmeters, touch panels and wiring.
Always identify the full machine version before selecting brewing-group or electronic components. The designation printed on the machine, serial plate or original controller is more reliable than the general model family alone.
Regular cleaning cannot prevent every technical fault, but it helps keep the brewing group, solenoid valves, steam system and water circuit in good condition.
Common maintenance tasks include:
Do not replace components or descale a commercial machine without considering its water treatment, boiler condition and manufacturer instructions. Incorrect descaling can release deposits that subsequently block valves, flow restrictions or pipes.
Record the complete machine model, version and serial number. Also note every code printed on the original component. Clear photographs of the part, its electrical or hydraulic connections and its installed position can help distinguish between similar versions.
