Hughes Power Watchdog EPO error code E6
Line 2 and neutral reversed (50 A units only) - the pedestal has a hot and neutral swapped on line 2. The Watchdog will not pass power; after the fix it must be unplugged and re-plugged to reset (manual). The current Power Watchdog FAQ's manual-reset list (E3/E4, E8) does not include E6 - a source conflict.
What to check, and in what order, is in the app. The flow RV surge protector / EMS fault lookup walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
