There is a tiny black plug which, if inserted into the hole on the very top left, will divert the water flow to the back. I believe the tiny black plug may be in the top right ready for you to take it out and put it in the top left drain. Now, my problem. After several years of having a daily flow of water I now have no water produced at all anymore. The humidity is quite high 79 and the setting is for 60. What could make it just stop taking the water out of the air?
