Frequently Asked Questions

What does the solid state relay do in the Lelit Bianca?

The solid state relay (SSR) acts as an electronic switch between the PID temperature controller and the boiler heating element. When the PID determines the boiler needs more heat, it sends a low-voltage control signal to the SSR, which switches on the mains AC circuit (230V 25A) to power the heating element. SSRs have no moving parts and fail silently — a failed SSR is a common cause of a Lelit Bianca that no longer heats up.

What is the Carlo Gavazzi RF1A23M25?

Carlo Gavazzi is a leading manufacturer of solid state relays used in commercial and professional espresso machines. The RF1A23M25 is a panel-mount SSR rated at 230VAC output and 25A load current — the OEM specification used in the Lelit Bianca PL162T.

Should I apply thermal paste when replacing the SSR?

Yes — thermal paste should be applied between the SSR and its mounting surface (heatsink or chassis) to ensure efficient heat transfer. Without it, the SSR overheats and can fail prematurely. Always apply fresh thermal paste when installing a replacement SSR.
