F&P smartdrive machines do not have heating elements. The temperature sensor (called a thermistor) is fitted to the water chamber attached to the inlet valves & measures the water temperature entering the machine and sends the reading to the controller which will then regulate the hot & cold valves to give the correct mix. Put the hoses on the correct taps & run machine it may work ok. If the error comes up again change the thermistor. They are not very expensive & easy to change.
