Whilst I’ve never had a issue with our Humidifier, I do know its a hot subject on here. 

There’s a similar post from a few months back that might help. 

Seems it could be two issues. Something missing from the original set up or a fault.

Good luck.

I got it working yesterday . I tried the article but had no joy so i then  looked at the mechanism that is the water and took part of it off . There is like a thin grill filter that appears the suck the water up . This had some type of glue like substance in it(like a label was removed from the inside of it and never cleaned) . I washed that with warm water  to remove this and it fixed the problem .
