Daikin h8 error

Hi, I've got a Daikin inverter a/c with an external model RX25HV1NB, which gives me an error code H8. I would appreciate if anyone can give me any troubleshooting tips before I change the external PCB. Note that it starts either in cold or hot modes and stops in a few seconds.On the external part the green and the next two red lights then remain on. Is there any way to check the current transformer or the thermistors?

H8 refers to a fault with the AC input current sensor system or the current transformer or an associated abnormality.

Dear frank, thank you for your reply, but this is where I am wondering what I have to check, is there something that usually causes such a malfunction?

If you mean is there a common fault... the answer is no I'm afraid.
