Try placing a book under the front of your AquaCure and turning on the gas production. If the overfill warning turns off and the gas production starts, you can leave the book under the front of your machine for a day or two. If the overfill light is still on, you’ll need to remove the tower and pour out a small amount of the lye solution.
To avoid overfilling in the future, please read below.
Bubbles can become stuck in the tubing inside the AquaCure, including the viewing tube. This can cause false water level readings and lead to overfilling. Try tipping the machine forward 45º and watching the viewing tube to ensure the solution inside has pushed all the way through. Then tip the machine backwards 45º until the viewing tube is drained. Repeating this a couple of times will purge any bubbles from the lines.
Because the tubes are quite narrow, it does take a few seconds for the water level to rise after adding water to the AquaCure. Tipping the machine forward will help push the water into the viewing tube more quickly.
