Definitely not an electrical smell.
My theory is: The electronics module is flaking due to power issues or something and one element stops heating. The water does seem to be hotter after resetting, even days after.
And also the smell would go away. But weeks later the smell would come back. Beginning to think we don’t use enough hot water. Just 2 in the house, showers every AM, dishwasher, clothes washer. I don’t remember the size of tank i bought, could be a 40g.
I did recently reduce the temp on the tank from 140. Gonna crank that back up to see if it changes anything.
