The dough mode and turbo mode will both be deactivated if the temperature is above 60°C / 140°F. If you want to use either of these modes, you first need to make sure that the contents of the bowl are no hotter than 60°C/140°F. If they are, you just need to wait a short time until the temperature has cooled down. How long this takes will depend on what kind of food is in the bowl.
