Replacement 175° C. Thermal Cutout Switch for the 35 Liter Brewzilla and Gen 4 Brewzilla. This is what shuts your unit off if you mistakenly turn it on without water in the boiler. If this goes bad, your unit may display an E3 or E4. This switch is mounted directly to the bottom of the boiler and if the boiler bottom gets too hot the bi-metal switch will activate and cut power.
This can be used with all 3.0 or higher Robobrews or Brewzillas, although earlier Robobrews had spade connectors, and you will have to adapt the screw connectors on this switch to fit the earlier Robobrew spade connectors.
