This is the OEM water level auto-fill control box for the ECM Giotto espresso machine, using the industry-standard GICAR 9.9.04.76G module. It monitors boiler water level and automatically activates the pump and fill valve to maintain the correct level — essential for consistent pressure, temperature stability, and machine longevity.

What Does a Water Level Regulator Do?

The water level regulator is one of the most critical components in any commercial or prosumer espresso machine. When the boiler water drops below the probe threshold, the GICAR control box triggers the pump and opens the fill solenoid to top up the boiler automatically. A failed regulator can cause dry boiler conditions, inconsistent steam pressure, or machine shutdown — making timely replacement essential.

Symptoms of a Faulty Water Level Regulator

• Machine continuously fills or never fills the boiler
• Low water warning light stays on despite full reservoir
• Pump runs constantly or erratically
• Steam pressure drops unexpectedly during use

Installation Notes
