Frequently Asked Questions

What does the water level regulator do?

The water level regulator (auto-fill control box) 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 Rocket Espresso part?

Yes, this is a genuine OEM Rocket Espresso replacement part (A199907550).

Can I replace this myself?

Water level regulator replacement involves working with mains voltage electrical components. This repair should only be carried out by a qualified technician. Our Sydney-based team can assist — contact us to book a service.
