Basement flooded to two feet (good times!). Technician is here - boiler will turn on but is not heating the water. Per technician, could be one of several sensors, he will have to try to fix the first, see if it works and if not fix the second (etc.)
Any thoughts on which sensor would be most likely to go in flood situation?
