EQ6 Message Restart device

Hello dear forum ,

I have a Siemens EQ6 coffee machine and am actually very satisfied so far. Now I get but more often the message device restart. This message comes when then always shortly after switching on.
Machine is decalcified 1x a month, cleaning program after request, BE weekly 2x thoroughly cleaned also the spring area.

All 3 seals have just been replaced and running rails of the BE as well as seals and springs are greased.

In the service menu under errors I found the following:
Ceramic valve timeout 3Pump
timeout 1Overtemperature
43Temperature
at shutdown 1Inadequate
pump 36CV
recalibrations 1No

error log filed.

What is wrong with my machine? Can you help me here?

Thank you very much!
