Hi folks,

So our diesel heater decided it didn't want to work anymore.

It turns on and just blows cold air.

Neither the pump or glow plug icons are displaying on the control unit.

There are no error messages, I've changed the glow plug just incase and made sure the fuel pump works by manually turning it on for 20 seconds via the controller.

There is fuel in the line all the way to the heater.

Any help would be appreciated, as it bloody freezing.
