I have just replaced the group head on my machine and now it reaches 69 c and stops. Light around power button continues to flash. Setting is still at 93c. Any ideas on why the temp is not being reached. I could have made a mistake re assembling after replacing group head but do not know where to start checking. Any advice much appreciated.

I advise that you go back into the device, look at the connections, any connections that you had removed to complete the replacement.
