Re: indesit idl535 lights 1+3 flashing
check the thermal fuse in the circulation pump windings
it may have faiuled due to thermal and mechanical stress
i found this today 3 in a row all thermal fuses
one had loose tags and when i moved the connections on it
it worked then not
so check the sensors
and other mechanical parts for jams
the pump for blockage and the circulation motor
for windows fuses
