Salt Indicator Light Flashes Permanently On Indesit IDE 750 dishwasher

I think I have the answer.

On Yahoo Answers Blue Rizla Girl put up the idea that the sensor is some form of hydrometer. (i.e. floats in salty water sinks if not salty enough)

Based on this thought I postulated that the sensor is some form of hydrometer float in a tube with perhaps an optical sensor.

If this is correct why is it not working?

Is it because the float is stuck at the bottom of the tube, perhaps by some food debris? If so how can we fix it?

This is what I did on my Hotpoint FWD60:-

I took the salt filler cap off. There was no salt in the reservoir as it has been a problem for months, and I was only refilling it when dishes were not coming clean.

I poured 2 litres of hot water into the salt reservoir.

I then put the empty machine on the intensive 65 degree wash, half load and with the reservoir cap still OFF.

When finished I filled up with salt and HEY PRESTO the salt light is OFF!!!!

Just hope it stays that way until the reservoir really needs refilling.

While I was down on my hands and knees I took the opportunity to clean the filters in the sump. They do get full of bits!

I also flushed the sump by dashing a couple of cups of hot water into it and then bailing it out with a small yoghurt pot. I repeated this until the water in the yoghurt pot and the sump no longer had any signs of bits in them. (Dashing = vigorously pour)

I was amazed at how many bits I got out, especially considering I had given the machine a good clean in the past 6 weeks.

I even got part of a paper label!

So there we have it, try it out and report back.

Funnily enough I'm just looking at this site to try and get a copy of the operating instructions for our IDL 730 as I've only seen and read them once ... then we lost them !
I do remember though, when I read the instructions, that they stressed that when you filled up with salt it would take several cycles before the lidght would stop flashing.
Maybe that had something to do with your problem ??

I've had the same problem on my Indesit (IDL-730, IDL730) and after pouring in salt until full for ages, without the light going out, I finally decided to do the reverse.
I left it to run down the salt over a couple of months, until well empty (not ideal, but I was getting desperate!), and then finally refilled it.
Problem solved - salt error light was no longer on
All I can figure is that a blockage had set in and casued the issue. Leaving it to clear over time sorted it.
Hope this helps in your situation.

Which type on salt did you filled the salt try?
