Good evening,
I am the owner of a James COOk compact 2008 since early January, and as the good days come back I live in the south west and prepare the vehicle to leave and those there that the problems begin, I switch the heating and realize that after 5 minutes the code arrows crossed out, we can hear the gas oil pump of the smoke coming out under the vehicle, same for the boiler, I took it apart under the sink and there is liquid but when I activate the red valve nothing happens so I think that the circulation is not as much in the radiators as on the boiler. If someone had an idea or if it had already happened to him I would be very grateful.
And then I say to myself I'm going to make the refrigerator work at the connection box, I mount it to the maximum, no compressor start, I changed the fuse behind the bench like that and I don't have any error message that appears.
For a start I accumulate them or maybe I forget to do something.
Thank you for your attention to my message.
