The heating and hot water are not working in our van. No lights coming on for them at all and there are 0 amps showing on the control panel. Everything else working: fridge etc

Any ideas?

There may be a power supply fuse on the 12v habitation fuse board that is faulty , or it could be the 12v fuse that is under the wiring cover on the boiler that needs replacing.

If it’s anything like ours - if the input voltage from the mains or solar are outside certain parameters it won’t work
If you unplug mains does it work- similarly if you disconnect solar
We have had this on a few sites where the mains voltage was a bit low

Looks to me like the controls are between settings.

It might be worth waiting for the OP to return before spending too much time on this.
