All your fuses are checked and good? What about other 12v functions, pump, loo flush, any 12v sockets?

Sounds like a flat battery or blown main fuse.
Check your battery with a multimeter, you're looking for 12.7 volts or more. Anything less it may need charging or replacing.
Check along the red wire leading from the battery into the van. There should be an in-line fuse close to the battery box.
