Fault codes are listed in order of hierarchy. For example, if during cooking the oven experiences an F1 and F2 fault, the oven will report only the F1 fault because the software will halt all actions upon discovering the F1 fault.
Fault codes F1 - F5 and F7 will terminate a cook cycle upon discovery.
