I wouldn't mess around with trying to fix it myself if the item is still under warranty. If you are smelling burning, and safety mechanisms aren't working, I'd be very careful about continuing to use it.

Do you still have your invoice? At only 2 months old, the unit shouldn't be malfunctioning like that. Best thing to do would be to take it back and exchange it for a new one. If the place you bought it from won't take it back, then call Honeywell directly. Honeywell should cover either fixing it or exchanging it under warranty.

Maybe the hose is blocked. Take the hose off the supply side, and blow into just enough to add pressure to it and see if that works.

You will need a multimeter to check if the humidifier is receiving 24 volts from either the furnace control board or transformer. If you have 24 volts to the solenoid, but does not open, then the solenoid valve will need to be replaced.

I have same problem with no water flow on identical humidifier but was able to fix it. Removed the inlet to the solenoid valve and found (1) a small taper mesh filter inside (2) a small diameter orifice that was clogged. Cleaned the miniature filter and used a sewing needle to open the orifice and now works perfectly.
