Re: Indesit WIDL 102 door lock light
Just in case it helps, I have the same machine and have had both symptoms you describe. The issue with the top vertical LED coming on, but the door lock light remaining unlit and the click missing happens when I don’t close the door with a sharp bang. I presume it’s a faulty switch there or a very sensitive one that needs the door fully locked into place.
With the flashing lights, that worried me as I thought main PCB failure, but it turned out to be softener that had run behind the front facia and onto the PCB with the control button microswitches on it. I presume it was causing some voltage signals to be sent simultaneously and erratically to the main PCB and was confusing it.
A thorough clean with isopropyl alcohol, including removing the dials and cleaning the contact squares and wipers beneath, restored normal operation, as well as finally sorting out the start cycle button, which usually required pressing hard and fiddling with to get the machine going – it just needs a light press now.
