Dishwasher tablets annoy me - I want some bog standard dishwasher
tablets.
I don' want the ones that have salt and rinse aid and lord knows what
else
in at 30pence a tablet :-(

You should be annoyed.
There is no way the tablets can replace the salt in the dishwasher.
The salt regenerates the ion exchange resin in the softener.
The dirty water with the "salt" function in it doesn't go anywhere near
the
resin.

We went through all of this a little while ago after I raised the same
point. The conclusion was that it isn't actually salt, but a replacement
water softening agent.

I just turn the softener on my DW down to '1' so there's a bit of
both.

But do you still put salt in?
If you don't you could ruin the ion exchange resin and then you would always
have to use a "salt" substitute tablet.
I suspect that is their intention.
