Bosch HBL8451UC 800 Series 30 in Single Convection Wall Oven E013 Error Fix: Oven Maximum Temperature Exceeded

Error code E013 on the Bosch HBL8451UC 800 Series 30 in Single Convection Wall Oven means: Oven Maximum Temperature Exceeded. The oven cavity temperature has exceeded the maximum safe operating temperature (typically above 600°F in normal bake mode). The control has shut off the heating elements as a safety precaution. Check the oven temperature sensor — if it is reading incorrectly, the oven may be overheating. Check the control board relay — a welded (stuck-closed) relay can cause the heating element to run continuously. Check the door gasket for excessive heat loss that causes the control to over-compensate.
