The HWO130 is a Heritage Professional single oven: 4.8 cu. ft., Four-Part Pure Convection, Glass Touch controls and SoftShut hinges that ease the door closed. Its manual shows codes as a letter and two numbers, and C33 is the one owners meet most, usually after broiling with the door propped open.
Dacor’s Heritage manual is explicit that C33 can come from an open door during broiling and that the oven must cool before the code resets. If C33 appears with the door shut, the cooling system is the next place to look.
