Don't cut any of the food whilst it is on the appliance. Only use wooden, plastic or non-stick utensils. Never use metal utensils as they can damage the non-stick coating of your appliance.
After following the instructions in the user manual for starting the appliance, make sure that your electrical socket is working by plugging another appliance. If it still does not work, do not try to dismantle or repair the appliance yourself, instead, take it to an approved repair centre
