Ender 3 V2 Causing Circuit Breaker to Trip (Even when PSU is flipped off!) (lemmy.zip)

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?

One with an internal fault. Where do you live in the world? Are you in Europe or the UK where you have RCDs in your breakers?

Unplug the PSU from the wall and everything else for a while and then check the connectivity between all the pins that go to the wall outlet. Do it with both the switch on and off.

Ah, should note that I'm in the US. I'm also not on the 230V mode and I'm using the 115V power mode, which is standard for my region.

You'll need something that can check conductivity.
