Guide :Humidifiers : HDC12 Humidifier
Left Tank won't empty
I just bought an Emerson HDC12 recently. I have made sure the unit is level front to back and left to right.
I have filled both tanks with water and run it successfully until the F light lites up telling me to refill my humidifier. However the left tank stays full and never loses any water at all.
I have switched the plungers between the tanks, I noticed the post for the left plunger is much lower so I stuck a spacer on the bottom of the plunger to offset the difference between the tanks, and lastly I am now trying the empty humidifier position. (Tying the float up stuck in the on position.)
