Creality 3D Ender 5 Pro Bed overheating


I have recently bought a Creality3D Ender5 Pro printer, and after about month or so it started to overheat the bed.

Meaning: the moment I switch on the printer it starts to heat the bed, and does not stop until I switch off. The display shows me, at the temperature setting is at 0°, and that it is heating to the maximum temperature.

I have checked all the cables, but haven’t found anything.

Does anyone have any idea what could be causing this, and what to do about it?

Kind regards,
