MacMaxe 3/2 Way Solenoid Valve – CEME V397VN25PR44 – 110-120V 60Hz – Replacement for Breville Espresso Machines

3-Way Solenoid Valve Setup Instructions Port Functionality and Operation: Port 1 (Water Inlet - Common Port): This is the water inlet port in both the energized and de-energized states. Water always enters through Port 1, which is clearly marked on the plastic connector. Upper Connector (Normally Open - Water Path when Solenoid is Off): When the solenoid is not energized (off), water flows from Port 1 to the Upper Connector. This is the default state, where water exits through the upper connector. Port 2 (Normally Closed - Water Path when Solenoid is On): When the solenoid is energized (on), water is redirected from Port 1 to Port 2. The Upper Connector is closed, preventing any water flow through it in this state. Port 2 is also marked on the plastic connector for easy identification. Correct Operating Mechanism: 1. When the solenoid is off (de-energized): Water flows from Port 1 to the Upper Connector. The connection between Port 1 and Port 2 is closed. 2. When the solenoid is on (energized): Water is redirected from Port 1 to Port 2. The Upper Connector is closed, stopping water flow through it. Important Notes for Proper Installation: 1. Port Markings: Port 1 and Port 2 are clearly marked on the plastic connector, making it easier to correctly identify the inlet and outlet connections. Be sure to connect the system properly based on these markings to ensure correct operation. 2. Bottom Plastic Connector Swivels: The bottom plastic connector swivels and must be correctly adjusted according to your system setup. Incorrect positioning may prevent the valve from functioning properly. Ensure the alignment of the swiveling bottom connector is correct before installation. If the order of connections is mixed up, the solenoid valve will not work as intended. 3. O-Ring Installation: Place the O-rings (included in the package) on the connectors that will be inserted into the ports. These O-rings are essential for creating a proper seal between the connectors and the ports to prevent any leaks. Ensure that each O-ring is properly seated on the connector before inserting it into Port 1, Port 2, and the Upper Connector to secure a leak-proof fit. Flow Summary: Solenoid Off: Water flows from Port 1 (inlet, marked on the connector) to the Upper Connector. Solenoid On: Water flows from Port 1 (inlet) to Port 2 (outlet, marked on the connector), and the Upper Connector is closed.

• If you can't pour a shot before it buzzes and stops, you likely need a 3-Way Solenoid Valve to fix the issue. If you're buzzes after a shot but otherwise works, the 2-Way Solenoid Valve is the solution, as it handles pressure relief after brewing.
