The Aquahot quit working, and on inspection a circulation pump had gone bad. Very common problem, pump replaced under warranty. Took it to my friend Rudy Legett who replaced the pump with one of the new Buehler pumps, much better quality. Now both pumps are Buehlers.
Some smaller things. Added a small slide tray in the front bay so I can have easier access to my tool box. Moved the subwoofer from the dinette to behind the fireplace (lots of space there!). Added a wine rack where the subwoofer was.
