I am now on my 3rd water heater, everything has been replaced, except for the gas line that feeds the heater itself. The installer did use a tool to check for leaks on the gas line though. The heater is an AO Smith 50gal with power vent and a honeywell control module. They keep having the same issue, FVS Fault detected, or the 8-1 blinking code. I have had professionals install the heaters each time, but they can't figure out the issue. Please help!
