Remedy

Ensure flame rod is touching flame when unit fires. Check all wiring to flame rod for damage.

Remove flame rod and check for carbon build-up; clean with sand paper.

Check inside burner chamber for any foreign material blocking flame at flame rod. Measure micro amp output of sensor circuit with flame present.

Replace flame rod.

Flush heat exchanger. Refer to instructions in manual. Replace heat exchanger.

NOTE: The LC code is the only error code that will allow the unit to keep running. The display will alternate between the LC code and the temperature setting. The controller will continue to beep. The LC code will reset if power is turned off and then on.

Clean inlet water supply filter.

On new installations ensure hot and cold water lines are not reversed.

Check for bleed over. Isolate unit from building by turning off hot water line to building. Isolate the circulating system if present. Open your pressure relief valve; if water is flowing, there is bleed over in your plumbing.

Ensure you have at least the minimum flow rate required to fire unit. Ensure turbine spins freely.

Measure the resistance of the water flow control sensor. Check for DC shorts at components.

If any of the above diagnostic codes are seen flashing on the display, call for service.

WARNING

Failure to remedy faults may result in severe burns, scalds, and/or death.
