When switch on the machine it doesn't make the self test and when start the case it gives an alarm (Alternate O2 Screen), so should I replace the mixer or just one valve?

You have to go through the troubleshooting procedure in the service manual. Try zeroing the pressure transducers or check the alt O2 switch...could be simple and not the mixer. The service menu has extensive tests/info for the machine that should point to the problem.

My analysis that there is something wrong in the mixer that's way the machine asks to open the alt O2,is this could be right?
