What should I do if the cooktop displays a flashing symbol on the element display?

A flashing symbol indicates the touch control zone is wet, very dirty, food has boiled over, or an object is lying on top of the touch control zone. Clean the touch control zone or remove the object and lightly touch the corresponding touch key. If the display still does not light up when you turn the element off and on again, disconnect the appliance at the circuit breaker, wait 20 seconds, and reconnect it. (Page 21)
