A reset can remove a useful message without resolving the cause. Preserve the display and circumstances first unless immediate safety requires stopping the appliance.
What the observation tells you
The evidence includes the exact characters, which indicator flashed and what was happening at the time. Guessing afterwards can send an enquiry toward the wrong issue. A return to a normal-looking screen also does not prove that the cabinet recovered.
A useful next step
Follow only the documented owner reset if appropriate. Avoid repeated power cycling or service-menu experiments. Include the warning record and subsequent temperature behaviour so an assessment can consider the whole sequence.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
