Rocket Espresso Giotto Pressurestat / Pressure Switch Restore accurate boiler pressure control to your Rocket Espresso Giotto with this replacement pressurestat (pressure switch). The pressurestat monitors and regulates boiler pressure by signalling the heating element to switch on or off — when it fails, your machine may overheat, fail to reach temperature, or cycle erratically, directly impacting espresso and steam quality. Compatibility Rocket Espresso Giotto Confirm your machine's pressurestat specification before ordering — contact us if unsure Symptoms of a Faulty Pressurestat Boiler overheating or not reaching operating temperature Pressure gauge reading too high or too low Machine cycling on and off erratically Weak or no steam output Heating element not switching off correctly 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 shot and steam quality. Is this the correct pressurestat for my Rocket Giotto? This pressurestat is listed for the Rocket Espresso Giotto. If you have a different Rocket model or are unsure of the correct specification, contact us with your machine's model and serial number before ordering. 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.
