K1 Max lost power internally during a print job

Flagship K Series

I was printing a part using ABS filament. It had been in the Creality filament dryer for over two hours. After 80% part completion, the machine lost internal power. I checked the switch at the back and it is still turned on. Also, checked the incoming power and confirmed 110 VAC being supplied to the K1 Max printer.

What should I check???

Its sound like brown out, maybe ups in the future.

This has hapened to me with my k1. It turned out that the cable wasn’t in the printer all of the way.
