It may indicate pan detection or another state defined by the model. The exact symbol and sequence matter more than the general fact that it flashes.
What the observation means
A removed, undersized or unsuitable pan can prompt a response without establishing an electronic fault. Other warnings may use different flashing patterns.
A useful next step
Check the manual and compatible cookware guidance. Record whether the flashing follows one pan or affects all suitable pans. Do not repeatedly raise the setting to force heating, and do not assume a code found for another brand has the same meaning.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
