Marquis euphoria spa won’t turn on

[Umair]

Hey hi,
We have a marquis euphoria spa. Very new to the whole thing and mostly following the guide which was super complicated.
Anyway I think I messed up something because after keeping the spa on for half an hour I smelled some sort of burning and then the spa shutdown.
I tried to turn it on from the main switch but the breaker (main power line) does not turn on.
I opened up the spas backside to see what could have gone wrong. But there are no visible signs of burning. I also opened up the control box and heater section (650-0519) but no fuse seems to be blown.

Does anyone have any idea what could have gone wrong ?

Thank you in advance for your help

Hi,
The problem is now fixed.

I opened up the control box and unplugged all grey wires coming into the control box (light, pump and ozone).
I then plugged them back in, restarted the spa and it worked fine.
