Question about Emerson HDC12 Humidifier
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.) I won't know if this works until that right tank empties again. I can let water out of the left tank if I push up on the plunger so it is not geetting stuck in there by vacumn (I think). This unit is supposed to drain the right tank before the left but I thought they both were supposed to drain before the float fell enough to shut off the humidifier. Anybody have any ideas on what to try next? Thanks
Eureka! Solved my "left bottle not emptying" problem. The problem was not with the bottle but that the top of unit which houses the on/off switch was not seated properly. It takes only a very slight difference in water level for the float to activate the switch, therefore if the top is raised even 1/4" the unit will shut off before the water level is low enough to allow the left bottle to drain.

I had the same problem from day 1 with my MoistAir HD14070.
I inserted a piece of 4' square ceramic tile under each front wheel. This raised the front slightly more (unit is setting on carpeted floor) and gave the unit a more firm base to sit on. Works like a charm now.
Hope this helps someone.

I've had the same problem. My solution has been to remove the plunger on the left tank. (Kind of defeats the purpose of changing the tanks without spilling water all over the place.) I really like the humidifier and this problem is minor compared with other humidifiers I've had in the past.
