Go have a look at the connector that plugs into the circuit board.
The connectors should have a bow shape. Use a dental pick and make sure the connectors are bowed and springy.
Your connection at the ECO has to be good or the water heater would not have fired when switched on. Power from ECO goes to gas solenoids.
I found this issue several years ago and then again last month while snow birding at Quartzsite. I had the very same symptoms as you, red light and lockout.
