I’m having a rather strange problem with my Ender 3 V2 that’s causing me to leave it unplugged and as a result underused.

I used to have my printer set up in my garage but one day noticed that the circuit breaker was tripping overnight resulting my refridgerator to turn off (not ideal.) I kept removing devices until I determined that it was caused by my 3d printer despite the PSU being completely flipped off at the back! This is obviously strange behavior and not ideal for a device that is outside of it’s warranty period.

So I’m not sure how to proceed here. Firstly, what type of issue would cause this device to trigger a circuit breaker even when the PSU is turned off? Secondly, is there some way to fix this device that isn’t a major PITA? Has anyone else experienced this as well?
