just the noise of it kicking into life – There is a click, then about 10/15 secs gentle hum and it fills but then it just seems to freeze. No code comes up, it just doesn’t move on. If I then turn dial off and try again on new setting there is a brief hum/drone and it stops again, as though it tried to get going but stalled. The start light flashes at this point but doesn’t respond to pressing.
