That's most likely the main (top) PCB. In some cases they can be reset or adjusted. If its an early machine, there is a screw on the board to adjust it. If its an X4 Pet Eco, and an 1100w, its probably a circa 2017-19 model and they can be reset only with a tool.
However, if its just started doing it, I'd suggest its maybe 30% likely it will reset and 70% likely it will need a new board.
Check if its still under warranty. They have five years.
