9 times out of ten this means that you have a faulty water pressure switch. It could also be a limit switch, or air pressure switch. Make sure the filter is cleaned, and all valves are in the correct position. Once you are CERTAIN that water is flowing through the heater, you will need to short each individual component to find the faulty one.

SOURCE: Error code LO
Is the heater installed indoors?? if so you'll need a vent pressure orifice kit.
if not check your water press. (below 18 PSI on filter) Place filter on "recir" if it fires and stays on . it's the pressure.
check to see if all connections a set tight hi-ltd switch wire harness etc.

Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.

If communication between the ignition board and the display board is not established
within 3 s of power-up an error will be displayed. After communication is
established, if it is lost for 30 s, the error will be displayed. The error code will
be cleared upon a valid data exchange between boards.
