Hi, I have an aging ADG211 slimline dishwasher which has been functioning very happilt for many years. It's just started flashing a fault half way through a wash cycle, when it then stops and drains the wash. 3 lights come on flashing - power, wash and end, as is in the photo attached. These just blink constantly and the cycle stops. The water empties, so no blockage and the pump is working. The heater is also working fine. I suspect it may be overfilling a little as there is a small leak from the front door and when opening in the cycle it looks very full at the bottom - fuller than usual and then leaks around the door hinge when closing the door again.

Looking at the fault code list on this website it seems to indicate either pump failure or main board failure (I'm not sure which one is LED 1 - the power or the wash). However, it doesn't seem like either of these are the issue. I suspect the fill level sensor has got blocked with gunk. Does this sound reasonable? If so, where is this sensor located?

Many thanks for any help
