Frequently asked questions

What is the part number?

The listed Gaggia thermostat reference is 421946504761. Compare this reference, the 107°C marking, mounting thread and connections with your original part.

Is this the brew or steam thermostat?

This is the 107°C brew thermostat. Do not confuse it with the 145°C steam thermostat, listed under references 421946504771, 996530054612 and DM1288. These serve different temperature-control applications.

Will it fit my Gaggia Classic E24?

Classic E24 is included in the supplied compatibility listing. Confirm your machine's exact version and required part number against its parts diagram before ordering.

Will it fix cold coffee or a machine that will not heat?

No heating, lukewarm coffee or unusually hot water with steam can warrant checking the temperature-control system, but these symptoms do not establish a failed thermostat. Have a qualified technician diagnose the thermostat, heating element, wiring and other controls before replacing parts.

How should it be installed?

A qualified coffee machine technician should install and test this part. Disconnect power and allow the machine to cool before servicing. Avoid overtightening the threaded mounting, and never bypass thermostats or safety devices.
