MK4 Error 13309

I am getting an error message of #13309 with my Prusa MK4 pre-assembled printer. The error is "Overcurrent detected on xBuddy heatbed port, disconnect the device." This occurs early in the print, soon after the first layer. 

The printer has been working fine for the last week or so, then started consistently getting this error. The connections from the heatbed port and the xBuddy board look okay. The xBuddy board doesn't have any noticeable damage.

Is there anything else I can try?
