    Either NTC, connections to it or to the Module OR worst case scenario of replacing both the heater/NTC and Module.

    Thanks Martin.. but would it cause machine to fill and drain whilst lights flash and timer advances?? I have had NTC fault before but the filling thing makes me think module

    That is precisely the symptoms of NTC based probs. 🙁

    Itsa precaution to stop plastic tank melting (fill and drain) in the event of heater switching on with no water.

    Read that somewhere…

    I hate to tell you this Neil but that is incorrect I’m afraid. 🙁

    The NTC is purely a temperature sensor and NOT a heater safety device. Most modern plastic outer drum type machines these days use heaters that has an integral ‘thermotemp’ type fuseable link or links. So should the NTC fail or the heater be energised when there’s no water in the tub (i.e through a faulty pressure switch or jammed module relay). The built-in fuseable links turn the power to the heater off and NOT the NTC…!

    (Early Hotpoint (95 series) machines (for example) had a replaceable fuseable link that slots into the Heater, as you no doubt recall. These days they’ve done away with that idea altogether in favour of integral fuses.)
