Ariston LL64 error

Error messages:
Your dishwasher is equipped with a safety system which is able to detect any operating anomalies. These anomalies are reported by one or two wash cycle indicator lights "E" flashing rapidly.
Flashing Led diode below button with the image of wine glasses means faulty thermistor NTC. So, could be faulty: thermistor NTC (defective or not positioned), wiring, control board.

Please check if the pressure pump is clogged and the sparaying arms are rotating well. It is possible that the program seems to shut down due to an error. So start by clearing the inlet valve, check the flow to the pump and the spraying arms.

You did not mention what model number that you had but this is what I found after a little digging:

From http://servicetechhelp.com/discus/messages/2801/6823.html?1205974228 :

usual place for a leak is thro the door main seal but it is possible to get a leak thro the dispensor. only way to check is split door, put it to work and see if it leaks in dispensor area
