Green flashing lights , what does it mean ?

my indesit IDL500 starts to fill up with water after about 3minutes the 2nd and 4th green light comes on and the machine stops

The user guide says this combination of lights means the filter is clogged - see page 9 of the guide.

hi from italy, my problem was the 2 nd and 4 th light blinking. the book ways clogged filter. the heating element was burned open. if you ohm this out you should find 100 ohms. if its open the machine will call in the water,start then go into alarm and drain the water. the element cast me here 28 euro and you will need 2 new clamps. the element goes on ariston,indesit hotpoint,scholets not like the old days ralph

green is on but idl500 dosnt do anything

I have an Indesit IDL 500, the machine will start fine but after about 20 mins the Ist and 2nd button start flashing. Can you help?
