The 3-way solenoid controls water flow to the group head during extraction and releases residual pressure through the drain after the shot — a faulty solenoid causes dripping, failure to brew, or water not releasing after extraction.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: E131F4304\u003c\/li\u003e\n\u003cli\u003eOutlet: ø1\/8\" conical\u003c\/li\u003e\n\u003cli\u003eMax pressure: 10 bar\u003c\/li\u003e\n\u003cli\u003eSeal: RUBY seal, orifice ø1.5mm\u003c\/li\u003e\n\u003cli\u003eCoil: 483510S6, 9W, 220\/240V, 50\/60Hz\u003c\/li\u003e\n\u003cli\u003eFluid temperature range: -40°C to +140°C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Models\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWega Pegaso\u003c\/li\u003e\n\u003cli\u003eWega Atlas\u003c\/li\u003e\n\u003cli\u003eWega Polaris\u003c\/li\u003e\n\u003cli\u003eCMA espresso machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSymptoms of a Faulty Group Solenoid\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWater dripping from the group head when the machine is idle\u003c\/li\u003e\n\u003cli\u003eNo water flow to the group head when brewing\u003c\/li\u003e\n\u003cli\u003eResidual pressure not releasing after extraction (puck sticking)\u003c\/li\u003e\n\u003cli\u003eSolenoid clicking but not opening or closing correctly\u003c\/li\u003e\n\u003cli\u003eBurnt or failed coil (no click when energised)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdl\u003e\n\u003cdt\u003eWhat does a 3-way solenoid do?\u003c\/dt\u003e\n\u003cdd\u003eThe 3-way solenoid valve has three ports: it opens to allow pressurised water into the group head during brewing, then switches to release residual pressure through the drain line after the shot ends. This prevents the portafilter from being locked in under pressure and keeps the puck dry for easy removal.\u003c\/dd\u003e\n\u003cdt\u003eIs this compatible with my Wega or CMA machine?\u003c\/dt\u003e\n\u003cdd\u003eThis solenoid suits Wega Pegaso, Atlas, and Polaris models, as well as CMA espresso machines.
