When the PID determines the boiler needs more heat, it sends a low-voltage DC signal (3–32V) to the SSR, which switches on the mains AC circuit (240V 25A) to power the heating element. SSRs have no moving parts and fail silently — a failed SSR is a common cause of a machine that no longer heats up.\u003c\/dd\u003e\n\u003cdt\u003eWhy is thermal paste included?\u003c\/dt\u003e\n\u003cdd\u003eThermal paste must be applied between the SSR and its mounting surface (heatsink or chassis) to ensure efficient heat transfer. Without it, the SSR overheats and fails prematurely. Always apply fresh thermal paste when installing a replacement SSR.\u003c\/dd\u003e\n\u003cdt\u003eWhat is the Crydom CSW2425P?\u003c\/dt\u003e\n\u003cdd\u003eCrydom is a leading manufacturer of solid state relays used in commercial and professional espresso machines. The CSW2425P is a panel-mount SSR rated at 240V AC output and 25A load current, with a 3–32V DC control input — the standard specification used across many La Marzocco machine variants.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"La Marzocco","offers":[{"title":"Default Title","offer_id":46750658887876,"sku":null,"price":150.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/6632\/8260\/files\/2026-09-20075738.jpg?v=1789855192","url":"https:\/\/bearcoffeemachine.com.au\/products\/la-marzocco-solid-relay-25amp-with-thermal-paste","provider":"Bear Coffee Machine ","version":"1.0","type":"link"}
