your machine is flashing a fault code up, i need more information, now what should happen is as the dial goes round the on/off light will flash, only stopping for a 4 seconds the starting over and over again, until you turn it off, you need to count the flashes between the 4 second stops and give me the number of falshes for me to be able to help. but i would clean your filter out first.
