thank you all for the info. I submitted a ticket with Ultimaker.

I am a librarian and we offer 3D printing services. We've had an Ultimaker S5 for a few years now, and have recently had this issue. When I turn the system on, the print bed will increasingly get hot and not stop increasing regardless of whatever temperature I set it at in the system settings under print bed on the machine. It's gone as high as 140 degrees, and all without actively being in a printing mode. I believe this caused issues with our print head during a print, causing it to back up and ruin the entire print head. We are unable to use the S5 system at the moment. Does anyone know if there could be a fault of some sort in the machine? Any assistance appreciated.
