Indesit washing machine flashing 3 times

On certain Indesit washing machines (and Hotpoint), if the on off light is flashing 3 times, with a slight pause, followed by flashing a further 3 times, or if it is displaying F03 you have an error code that is explained as follows –

NTC fault – check Thermistor and module connections

The NTC is the thermistor, which is a modern-day thermostat. However, as this fault is exactly the same as the Hotpoint error F03 please read the advice on that article Hotpoint WD washer dryer flashing lights – error code F03
