These units improve serviceability by moving most of the components for the electric portion of the water heater to the outside except the element and relay, which remain in a junction box in the rear. One module board controls both gas and electric. When replacing a 3E or 9E to a 4E or 10E some wiring changes are necessary. -

water leaking from pressure valve when boiler heats up on both gas and electric. replaced valve but still blowing off
Water leaking from the pressure valve on an Atwood Pilot 6 Gallon boiler when it heats up could be caused by high pressure or temperature inside the tank. The pressure-temperature relief valve is a safety component designed to release water if the pressure or temperature exceeds safe limits. This can happen if:
1. The water heater is overheating.
2. There is excessive pressure buildup due to a closed system with no expansion space.
3. The valve itself is faulty and not sealing properly.
Make sure the valve is not blocked or restricted and is not removed or modified.
