Honeywell Truesteam problems

Hello everyone. I have had this very persnickity unit installed for the past two years. It took multiple visits from three different HVAC companies to get it to work right. It worked well for one year. Last year not so much, despite thorough cleaning. This year not at all. Currently it shows a cleaning is required. I've cleaned and cleaned and cleaned and the cleaning required light will not go out. The green 'humidifying' light stays on, and the amber cleaning required light. Water drains continuously from the pipe in the bottom. I opened it without draining just to see what I would find. The reservoir was about three quarters full of boiling hot water. But the unit is not blowing steam. I thoroughly cleaned it again, and made sure the drain at the bottom was clean. Now it has the red service light on as well. I am reluctant to call an HVAC company again to service it because nobody seems to have experience with these units and I spent so much on it so far. I'll try to fix myself now, or the unit is going in the trash. Any ideas? Thank you.

 

This is the only product from Honeywell that I don't like.. This has been the most pain unit by most people on here.. I've never serviced this unit in person so I would be no help. Sorry... :-(

I'd suggest to retire this unit, and get a simple bypass unit or if you have to stay with steam, do the Aprilaire 800.
