0.000 ppm is exactly what it should be reading.
As to why you are not getting any waste water I really don't know
But if you are getting no waste then you should be getting no pure either.
Unless you are set up in such a way that the waste outlet is totally blocked and everything is being forced through the membranes, which will ruin your membranes in very short order of course.
You are obviously producing water, so I can only assume you are plumbed in incorrectly
If you have the pressure to produce water, you will most certaily have sufficient pressure to produce waste.
If we assume the water at the business end is A-ok, there are pleanty of reasons why the windows are covered in spots.
First time clean for one, your inexperience for another.
It really isn't that easy to use WFP, there is a skill to it.
Have several attempts to clean your windows, experiment!
Wash your frames thoroughly first, and then the glass.
Move all around the upstairs first.
Then go back over the windows cleaning just the glass, always finishing drawing down from top...to bottom.
Buy yourself a hand held TDS meter, you can then do checks on your water purity at any point in the process.
You can then check your purity before and after your R/O membranes, ditto your DI and then of course at the brush end.
Make sure any container you use to check the water purity is thoroughly washed and rinsed with pure water too.
But don't expect to get it right straight away! Take your time and put in several hours of serious practice first!
Your own house, your neighbours, some family members and so on, if they are getting freebies they can't complain if you leave a few spots here and there!!!
And as David has said, make contact with either Craig or Reuben, Ionics are very pro and shouldn't let you down, they'll give you all the advise you need.
Going on the BWCA course is a very good suggestion too, it'll fast track you through an awful lot of the problems you'll encounter
best of luck
