There should be a way for you to add water to your incubator without ever touching the lid. The easiest way is to create a small hole in the side of your unit above the water channel (if you have two water channels, do one for each). Then you can run a piece of aquarium tubing down through the hole and to the top of your water channel. Be sure to keep it away from your heating element, and secure it somehow so it won't move around. Then you will be able to insert a plunger and add water as necessary. Then after you've done this, take a little while before your next setting to try it out with the bator running for a couple days, your goal here is to see if you can get it steady for the appropriate days. I.e. lockdown humidity levels. Doing this should make it easier to handle situations in the future. Hope this helps.
