Frequently Asked Questions

What does a pressurestat do in an espresso machine?

The pressurestat monitors boiler pressure and controls the heating element to keep the boiler within the correct operating range. A faulty unit can cause over-pressurisation, temperature instability, or complete failure to heat — all of which affect espresso and steam quality.

Is this a genuine Wega part?

Yes, this is a genuine OEM Wega replacement part (W10440).

Can I replace the pressurestat myself?

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