    Can anyone point me toward a fitting guide on how to change the DHW thermistor? Ive fitted a new Diverter and head a few months ago and all has been well up until i started to display H£ fault this morning :(

    I am presuming its the dhw thermistor on a ideal isar?
    - isolate the power supply and the cold mains and open hw taps
    - remove front and bottom covers, followed by securing bracket (underneath boiler - fitted with 4 screws)
    - the thermistor is fitted in the r/h manifold, remove securing clip and prize out using a flat blade screwdriver.
    -re-fit in reverse order using silicone grease on the thermistor o-ring
