Indesit washing machine error code 3 (F03)

On certain Indesit washing machines, if the on off light is flashing 3 times, with a slight pause, followed by flashing a further 3 times, or if it is didplaying 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. It’s inserted into a tube in the heating element and is filled with heat sensitive crystals that change their electrical resistance according to their temperature. By knowing what electrical resistance the crystals have at given temperatures they can tell the water temperature.

With this fault the NTC is either faulty, or there’s a dodgy connection to or from it or there’s a connection problem where it connects to the main PCB.

It’s not something you can easily fault find yourself unfortunately, apart from if there was an obvious broken wire.
