Before you book,
in this order.
Each step comes from Samsung's own guidance for tESt on its ovens. Follow it to the end: the last card says whether this is a visit.
Find the Demo mode steps in your model's user manual.
Turn Demo mode off as the manual describes.
Book a visit only if the oven still will not heat once Demo mode is off.
Cleared?
The oven came through without a new part. If the same message returns during a later bake, or the oven stops heating partway through, book it as a fresh problem.
What not to do
tESt is not a self-test result; nothing has been diagnosed or broken.
