10 year old water heater needs to be replaced.
Plumber who is also in the barony came and looked. Did stuff. Thermocouple was not the only issue. Wonky valve added to problem. The SIMPLE fix is to replace the whole thing. The model of the heater is generic and old and the whole assembly that would need to be replaced is going to be very difficult to find. So we go with replacing whole unit, get it back under warranty and know that I won't have to deal with it again for hopefully another 10-12 years
