Check the drum connector on the drum side and the machine side.Could be a bent plug.Have you tried a different drum to see if you get the same code?

i 've already check the drum side connector and machine side connector,i've already replaced a good drum assembly. but the problem is still there.

Well if you have swapped drums and have the same symptom its time to replace the main pcb and see if that works.Dont have a fuse table handy to see if one of the fuses controls the drum connection

So the country code was set wrong.Never crossed my mind that would cause that.Thanks for posting what you found.
