Hello @Sergii_Kozhukh :wave:
Welcome to the Creality Forum…! Creality-Logo

I had a similar issue with my Ender-3 that showed the same type of error. It turned out that some wires looked connected, but they were actually loose. Whenever the moving parts shifted the wires around, the error would come back.

I found it by accident when I moved the wire harness and the error suddenly went away. It might be worth checking the wire harness going to the heated bed.
