building wiring fault with unit only

BillP · ‎2021-06-28

Since a little while now, there is burning odor coming out of the unit and the building wiring fault light is lit on whenever i unplug my USB cable from the unit to my comp usb port. Nothing plug on the unit has a wiring fault problem, the light even lit with nothing is plugged in the back-up ES 750. it seems one of the plug in the unit is having a problem, since when i plug anything in this particular plug the red building wiring fault lit turn off.

I am quite concerned about that burnt odor coming out, since nothing different has been plug the in unit since i bought it not long ago.

Thanks for any help with this..
