Here i found something for you

My drain line was plugged and my resevoir and humidifier were not draining.

My resevoir has a wire in it, which I suspect detects high water and a problem.

Everything drains fine now, but I still have the flashing red light on my thermostat.

I did reset my thermostat. I sort of regret that now, since I might have change installer settings.

Thanks
