Hard Water Descaling Needed?
Georgia minerals cause code LC over time.
We perform pressurized lime and mineral removal flushes in under 60 minutes to restore maximum heating performance.
Schedule Descaling ServiceLikely Cause: Gas valve turned off, low gas supply pressure, dirty igniter rod, or electrical wiring fault.
Resolution: Verify gas line valves are fully open. If the unit still does not spark, our plumbers inspect ignition assemblies and gas manifold pressure.
Likely Cause: Venting termination blocked by debris, insect nests, or condensate blockage in the vent run.
Resolution: Clear external vent termination. If error persists, internal blower fans and venting runs require certified inspection.
Likely Cause: Hard water minerals have built up inside the primary copper heat exchanger.
Resolution: Unit requires a full chemical descaling flush with food-grade solution to restore heating efficiency and prevent warranty voiding.
Likely Cause: Flame rod sensing issues, insufficient gas pressure during high demand, or faulty grounding.
Resolution: Clean flame sensors and test operating manifold pressures under full faucet load.
