How often should it cycle on and off? Mine is cycling ever minute to ever minute and a half. I just bought this from a guy and he said his wife used it more than he did, but see got good hatches out of it. I think he said it had been 3 or 5 years since he used it. Some one had put a hole in the corner of the dome where I think a water bottle suppose to go in. I put some duct tape over the hole since I read your post to see if it helps. I should have a new wafer in the mail box I didn't check today. I'll put the new one in if it came and see what that does.
Every one please send me your post you think can help this newbee.

I plugged my roll-x in and let it come up to temp. It cycles on for 10-12 seconds and then cycles off for 30 seconds. It holds a steady temperature on a mercury thermometer. My guess is it would cycle on/off in less time once it had run for several hours.
The only way to tell how much water you need is to have an accurate hygrometer that reads the humidity.
The hole in the top is for a water bottle. You can order one online from McMurray Hatchery. It's part # 2L23
