Control panel NE216 (Chausson Flash 02) won't turn off

[Cest-si-bon]

I have a Chausson Flash 02 and the control panel won't turn off, it's a NE216 panel. All buttons work and turn off singularly, but the main switch, top right will not turn off which means I have to turn everything off before I leave the motorhome, I can't turn it off with the main power switch (even pressing for a few seconds). It was working fine.

Does anyone know if I can reset it?
