Rebalance a scaling Hansgrohe Ecostat Select by swapping the OEM thermostatic cartridge — restores TMV2 approval and 38 °C set-point.

Isolate hot and cold at the built-in EasyFit valves or dedicated isolators. Drop the pressure by opening the outlet fully.

Swap the thermostatic cartridge

Undo the temperature handle grub screw, remove the escutcheon and pull the cartridge with the OEM extraction tool — needle-nose pliers will crack the Hansgrohe plastic housing.
