A multimeter will tell you all you need to know about an element, along with Ohm's law. For instance, you know the voltage is 230V and you know the wattage of the element is 3000 watts. Ohm's Law (Voltage squared divided by the watts) tells you the resistance of the element in this case will be around 17.6 Ohms. If it isn't the element is faulty.
