Heat bed is not heating as expected : CB2565

Hello, my heating bed has been failing to "heat as expected" and throws an error code of CB2565. My question is does this code need a complete bed replacement or is it usually an easy fix? Also, if i need a new print bed, will the replacement bed for the SE work, or do I need a KE bed. I'm still new to 3d printing and this is my first hardware issue since i bought this printer a year ago.
