The WE I've been running at my desk just had the bed heater fail on it. I pulled the side panel and checked the wiring harness and everything looked good. The bed fuse seemed a bit warm, if that helps any.
Total print time on the machine was 17 days 12 hours 1 minute 4 seconds, with 70 prints on the machine.
Replacing the bed did not correct the problem. I will try tearing into the machine to see if I can find it.
