the temp, control valve is getting to hot!!! there for only let so much hot water go thru, did you take the inner parts out when soldering this in, if not you might have damaged it, and if so need to replace the cartdrige

The thermostatic stop is set too low. Havent set a grohe before but most other thermostatic shower valves work similar. pull off the handle(however a grohe handle comes off . . ) there should be a notched ring or stop which keeps the handle from going all the way hot. pull out the ring and turn it a few teeth hotter put back and reinstall handle try water temp and adjust again if necessary.

he probably put it together wrong.
there is usually a blue gasket inside for testing purposes, if that is not removed, the valve will not turn off.

The problem might be fixed by removing the cartridge and cleaning it thourghly and resetting temp stop.Yes the cartridge could be bad but new parts are readily available. Depending on water quality conditions in you area it may be difficult to disassemble so it may be a good idea to have a plumber do it for you. Thank you.
