What 1231
actually means.
On an M Series wall oven, 1231 means the control found the upper bake element's DLB circuit open, so the bake element in the upper cavity is not getting power the way the control expects. The same condition in the lower cavity is reported as 1232.

Before you book,
in this order.
Each step comes from Wolf's own guidance for 1231 on its ovens. Follow it to the end: the last card says whether this is a visit.
Turn the oven's circuit breaker off for about 30 seconds, switch it back on and try a bake cycle again.
If 1231 comes back, stop using the upper oven's bake modes and book a visit; note whether the lower oven still heats normally.
Still there?
It usually turns into bake and broil element repair. Book with the code and the model number.
What not to do
1231 is not a temperature sensor code. The oven may still light up and run its fans, but the bake element in the upper cavity is the circuit in question.
