Problem solved. There are two of those relay boxes that Richard was talking about, one in the closet under the main breaker and one in the Aquahot bay directly above the Aquahot. After a bunch of troubleshooting with Gurus and Newell we narrowed it down to a bad relay in the bay.

When I went to remove that relay from the bay wall low and behold what did I find? One of the 12v wires had broken right at the spade so 5 minutes later I was back in business. For an electrical novice it was quite a learning experience.
