Replace Grohe 47483000 thermostat

The Grohe 47483000 thermostat from a built-in unit you replace by pulling the tap button.

Then you loosen the nut around the thermostat with a 34 wrench.

Then you pull (sometimes with a little wiggling) the thermostat loose.

It may happen that the thermostat does not come out in its entirety (bottom part remains stuck).

You should remove that as well.

Once this is out you can clean it well and install the thermostat.
