The level regulator is connected to the level probe, which is typically located at the top of the boiler, although in some models (like certain Cimbali machines), it may be found on the flange side. When the water level drops below the level probe, the level regulator detects this change and opens the water inlet solenoid valve. Once the water touches the level probe again, the regulator closes the valve and stops the pump, effectively maintaining the desired water level in the boiler.
The water level in the boiler can be adjusted by raising or lowering the level probe inside the boiler. This allows for fine-tuning of the water level based on the specific requirements of your espresso machine. It’s important to keep the level probe clean and free of lime scale, as a buildup of scale can cause the level regulator to malfunction, preventing proper operation of the machine.
Some espresso machines also use a dosing device in conjunction with the level regulator to control the amount of water dispensed, ensuring precise and consistent water levels for every shot.
