    got a hpt wd420 there was a code which meant the stat on the dryer unit had gone, so changed that, but when i put it on a wash the dryer elements heat up and so blow that stat, anyone know why the dryer element would be coming on,no earth faults?

    Have you got a wiring diagram, I can probably fish one out for you if you think it might help.
