I have run into a problem with the Honeywell steam humidifiers. I have had this same problem twice now and Honeywell seems to have no answers. I am having a problem with the reverse osmosis filter not allowing the water flow to the humidifier. There is plenty of water pressure to the filter and all water goes to the overflow (which seems to be a terrible design to me). I have even capped the overflow off to try and get the water ther but had no positive results. Honeywell answer was give it 45 minutes to fill as they could not understand there is no water flowing to the humidifier. Any positive feedback will be greatly appreciated.
