Heated Bed Underheat Error Code: 515-5

Hi there
does anybody know this problem? I have a sporadic issue, that the bed target temperature (th eblue one…) drops suddenly to zero and in consequence the printer stops working with this mentioned message. I can then manually set the temp again and it resumes to work or stop/restart the printer and it will work again. this is very tiring, as the print interrupts mostly when nobody is watching it.

any solution for this issue?

Hi, how did you solve the problem, I have the same problem
