Winnebago EKKO Shore Power & Water Leak Fix - Expert Guide

Tools & Parts Needed

Immediate Solutions for Your EKKO Problems

Your shore power issue is likely a ground fault problem at the power source, not your RV, but this should be verified through proper testing. The red G light and 'OPEN GRD' error indicate the electrical pedestal or outlet you're using has a faulty or missing ground connection. Try a different power source immediately - this is a safety issue that prevents your converter from charging the batteries properly.

For the water leak above the driver's seat, this is typically caused by failed roof seals around the air conditioner unit or roof vents in that area. Water typically follows the interior structure and drips at the lowest point, which is often the cab area in many Class B designs.

Diagnosing the Shore Power Problem

The transfer switch indicator lights tell the story clearly. Green L and N lights show hot and neutral are connected, but the red G light means no ground connection. This creates an unsafe condition that prevents the converter from operating properly.

Test different power sources to confirm this diagnosis:

• Try another campground pedestal if available
• Test a different outlet at the same location
• Use a residential outlet (with proper adapter) to see if charging resumes

If the problem persists across multiple known-good power sources, you'll need to inspect the shore power cord and inlet for damage. However, given this is a brand new unit, a faulty power source is much more likely.

Tracking Down the Water Intrusion

Water leaks in the cab area of Class B RVs typically originate from several common failure points. The location above the driver's seat strongly suggests the leak is coming from the roof area directly above.

Most likely sources include:

• Air conditioner mounting gasket or shroud seals
• Roof vent seals (MaxxFan, Fantastic Fan, etc.)
• Antenna or solar panel mounting penetrations
• Roof membrane seams or edge sealing

Start your inspection on the roof directly above the leak location. Look for obvious seal failures, cracks, or standing water that shouldn't be there. Water can travel along interior framing before appearing as a drip, so the actual entry point may be several feet from where you see the leak.

Safety Considerations for Travel

The ground fault issue makes your RV unsafe to use with shore power until resolved. You should immediately disconnect shore power and not operate on shore power with a missing ground connection, as this eliminates important safety protections against electrical shock and fire. Always disconnect shore power before inspecting electrical connections.

The water leak, while frustrating, is less immediately dangerous but needs prompt attention to prevent interior damage and potential mold growth. If you must travel before repairs, place waterproof covering over the affected interior areas and avoid driving in heavy rain.

Next Steps and Warranty Coverage

Since this is a brand new unit with immediate problems, I'd strongly recommend returning to your dealer for warranty service. Both issues should be covered under your new unit warranty, and the dealer can properly document any problems for future reference.

Before making the trip back, call ahead and explain both issues clearly. Ask them to verify their service bay has proper electrical grounding so they can properly test your shore power systems. Many owners report that dealers sometimes have ground fault issues in their own service connections.

If you decide to attempt temporary repairs yourself, focus on finding a proper shore power connection first - this will restore your battery charging and generator starting capability. For the water leak, emergency roof sealant can provide temporary protection, but permanent repairs require identifying and properly sealing the actual entry point.
