The water level regulator monitors the boiler water level via a probe or sensor. When the level drops below the set threshold, it activates the pump and opens the fill valve to top up the boiler. Without a functioning regulator, the boiler can run dry, causing heating element damage and machine failure. Is this a genuine Bezzera part? Yes, this is a genuine OEM Bezzera replacement part (7661034.01). Can I replace this myself? Water level regulator replacement involves working with mains voltage electrical components.
