I sold mine not that long ago. It is like ANY piece of equiptment we buy for our ayatems, "IT NEEDS TO BE CHECKED"!!!!! It does alot for you but you still need to make suree the filters are not needed to be replaced. And that the float switch is working properly. And that the probe is calibrated properly.
I agree, mine was sold btw. I think it's a good machine, but it requires a lot of attention. don't set it up and think you can forget about it.
