E6: Over Temperature.
Outlet Water Temperature has exceeded 140°F (60°C) for 3 sec.
The main cause of overheating in this water heater is purging all of the air out of the plumbing and high temperature cold
water coming into the water heater. Southern states in the summer time can get extremely warm water right out of the
ground. When these conditions occur ensure that your water flow is proper.

Thanks John,
I've been researching it all day, I did read that same article.
I then purged all lines and heater itself, no luck.
I just filled my fresh water tank, ran water with coach water pump, repurged lines tried again. still no luck.
Any other ideas?
Thanks
