Ok. Where exactly is that ?

Where is the TDS meter installed or possitioned on your RO/DI unit ?

In that case, what Rebelson just said "it should be zero".

if you install your tds meter after the FIRST stage of filtration then obviously it's gonna have a higher reading than the second stage and so on...you must have the handheld one where you just dip it in the 'finished' product..
I have that same one Mark, and your description sounds correct 
I am assuming at some point your output did come out at zero? ..which is where you want it to be.
First you want to change out the cartridges on the bottom od the unit - the carbon and plain white filter looking ones, and the resin if yours has a resin chamber. If you TDS doesn't come down to zero, you may have to replace the membrane (the expensive cartridge), but try changing out the others first.
Many of our vendors carry these in stock

Input is 36 ppm ...from RO or tap water
and output is 6 ppm. .......form the DI correct

You can not have a output of .003 ppm TDS no TDS meter goes that low. You meter with that number must me in Siemens. Who's meter do you have ?
I need to know TDS of tap water, TDS of RO water to the DI, NOT the TDS of the waste water, which goes down the drain and TDS of the water leaving the DI. A RO will have two lines, one waster water and one clean RO water. The clean RO water goes to the DI input line. The "dirty" waste water should go down the drain.

What he's saying is the meter reads 003ppm which is 3ppm not .003ppm. The meter reads with 3 numbers.
