The electrical side of the water heater would not work and after some troubleshooting I isolated it to the rocker switch in the main control panel. After hunting for a replacement, I decided to take Bill Knight's (WDK450) advice (from an older post) and clean the external and internal contacts with DeoxIt and coat the contacts with NO-OX-ID. The switch works like a champ. What surprised me was how little corrosion (oxidation) it took to start causing problems...see the attached before and after pictures.
