The control area may detect an obstruction or unintended contact. A cloth should not remain there as a cleaning or safety barrier.
What the observation means
Touch-sensitive panels need the clear conditions described in the manual. Water across several sensors can produce a different response from a deliberate single selection.
A useful next step
Remove the cloth safely, stop cooking if necessary and clean only as instructed. If the panel remains erratic once cool, clear and dry, record the message. Do not press harder or cover the sensors to silence an alarm while continuing to cook.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
