I posted this once before and got an answer of using white vinegar. (I'm talking about cleaning out the top of the machine.) Well, that didn't seem to do the trick. After all, this thing has been up on "screech" production-wise for how many months already? Seems this is a good machine, just needs proper cleaning once in a while. So far, I haven't done a very good job of it.
Water has started tasting like something I don't want to describe. Probably has "wee beasties" in it, too. That is something I am trying to AVOID in the first place by drinking distilled water.
The company is a little difficult to get ahold of by phone, so I e-mailed them and they said HYDROGEN PEROXIDE--a 3% solution.
Lo and behold it works.
Just wanted to post this in case someone else had the same model and was running into the same problems.
