Frequently Asked Questions

What does the control board do in a La Marzocco Mini?

The control board (PCB) is the electronic brain of the machine. It manages boiler temperature via PID control, coordinates the pump, solenoid valves, and steam functions, and communicates with the La Marzocco Home app via Bluetooth.

How do I know if my La Marzocco Mini control board has failed?

Common symptoms include the machine not powering on, erratic temperature readings, loss of Bluetooth/app connectivity, or the machine failing to heat despite the element being functional. A faulty PCB is often identified after ruling out the power supply and thermal fuse.

Is this an OEM part?

Yes. This is an OEM-specification control board sourced for the La Marzocco Mini, carrying part number LM-E1027.

Can I install this myself?

PCB replacement requires disassembly of the machine and handling of mains-voltage components. We recommend installation by a qualified technician. Contact us if you need a referral to a Sydney-based service technician.
