Does anyboby know what a J1 fault is on a Jaguar 28?

As soon as I power up my boiler I get J1 fault.

does it actually stay in the display? its normal that it flashes J1 on power up then goes to normal display. Its just a boiler identification code. Is the boiler working?

No.

Pump doesnt do its 30sec run on power up, no heating ot hot water.

Gonna have to call an engineer me thinks.

Real fault codes on the Jaguar start with an "F"?

Regardless, check the water pressure and set it to 1.5 Bar.

After that does the pump run at all when there is a demand for DHW?

If not then it sounds like a PCB fault.

Systen pressure is fine and no fault codes showing.

I have cheked the board fuses and the gas valve controller fuse, they are all okay.

I don't seem to be getting voltage from the board to the fan or pump.

Overheat limit switch has been checked and is okay as well.
