We have an Ariston AFA 370x that has had a problem for a long time that it stops midcycle, beeps, at which time the 2nd and 4th green LED's start flashing. If the cycle was then restarted, most times it would then complete. Now however the day has come where none of the cycles will complete even if restarted. What do the 2nd and 4th warning lights flashing mean? Any help would be much appreciated ....
