Er3--is this an error message?
I bought this humidifier a couple of weeks ago, and now the digital panel just reads "Er3" instead of the humidity level, Hi/Lo etc. I cannot find in the accompanying manual what this means. Unplugging it and plugging it back in did not work. Then I tried emptying it out and refilling--it briefly went back to normal display but then back to the Er3 again. What do I do?
