For the past two days, I’ve frequently encountered the error “Heatbed temperature malfunction [0300-8009 214115]” on my relatively new A1 printer. While I can dismiss the error and continue printing without any noticeable issues, it still concerns me as it might indicate an underlying problem.
I searched the Bambu Wiki but couldn’t find any information about this specific error code.
Has anyone else experienced this issue or knows how to resolve it?
Hi, I have the same problem. Did you find any solutions?
I submitted a support ticket to Bambu, and they sent me a replacement heatbed to install myself. I haven’t installed it yet, but I will as soon as I have time.
does it says the heat bed cable may have an open circuit if it does go open a support ticket asap an they may send u a new heat bed if it doesnt say it {may have a open circuit
go to the wiki}
i had the same issue, and it only got worse after a while. Keep an eye on the bed temperature on the display and watch whats it’s doing. Mine would climb slowly then jump all over the place like up to 100C and then drop down and never really stabilize. I had filled out a support ticket, but decided to just do a return since I was still in that window (from Amazon). The replacement has been fine. So yes, there is a problem that needs to be address. Probably a new heatbed.
