    Chiron FZ15W fault help

    I currently have the fault code “ 700709 - flow sensor malfunction, coolant through tool “

    Does anyone know a remedy to this or where the flow sensor is located so i can inspect it ? Thanks.

    Should be easy enough to follow your high pressure coolant line from the pump all the up to the what I'm guessing is the top of the spindle. A liquid flow sensor would be something slightly substantial wouldn't you think? Of course there would be a wire coming out of it too. If you have the manuals they should give you a wire or connection number that you could look for that should be physically attached to the wire near any of it's connection ends. The documentation for your high pressure unit may be where you find it also. It wouldn't be unheard of to have the flow sensor as part of that unit instead of something supplied by the Chiron factory. (If your HP unit is from a different manufacturer.)
