Cilma Roca York - YCSA 26 T

Hi, I have a Cilma Roca York - YCSA 26 T that stopped working. Do you know any common faults of this type of chiller?

Also, do you know where I can purchase spare parts for it in Bulgaria. It is possible that the problem comes from its compressor and it needs to be replaced. Do you have any ideas how much a compressor for this model costs?

Any help will be appreciated!

What alarm cod displayed ?

Yeah read alarm code on YCSA controller.It has 2 digit alarm code.
