A word to take heed! Check the PH of your AH liquid. Most checks are done with litmus paper however electronic testers are available. If the PH goes acidic, the interior of the tank and the electric elements are subject to degradation. This seems to be the central problem in this thread, tanks or elements failing. The PH needs to be around 9 plus or minus a little.

I hope this helps.
