PlumbingDiagnostics & Troubleshooting4HighInstaller or Plumber$ implied
A newly installed Rheem water heater repeatedly shows a false leak detection error (A107) that prevents the unit from heating water, despite no actual leak and disabling the SOV.
Existing workarounds (SOV disable, sensor unplug) still don't clear the error or allow heating; the controller firmware ignores hardware bypasses.

Workarounds Described
- disabling SOV by setting 'SOV installed? - NO' and it still errors
- unplugging the cable to the SOV and manually opening it
- ignoring the code initially until it stopped working
Implied Software Gaps
- A diagnostic mode that allows temporary override of safety shutdown when sensors are known to be faulty
App Concept
LeakSense Bypass Tool
A hardware dongle or firmware override that plugs into the water heater control board to suppress false leak detection errors while maintaining actual leak monitoring. It lets installers temporarily disable the A107 error for diagnostic testing or until a replacement sensor arrives, saving hours of frustration.
Key Features
- Plug-and-play dongle that mimics a 'no leak' signal to the controller
- Toggle switch to re-enable genuine leak detection
- LED indicator showing current leak status from the real sensor
- Compatible with Rheem A107 error-prone models
Target Users: Plumbers and water heater installers working with Rheem (or similar) water heaters that have false positive leak detection errors.
Revenue Model: $49 one-time hardware dongle, or $19 for a firmware download (if controller supports USB)
