Fault Code E19
This display indicates that the line voltage frequency is out of range. This could happen if the unit is being
powered from a small gasoline powered generator that is not functioning correctly or overloaded.
Remedy:
Inspect power wiring to unit and repair as necessary. If connected to line voltage, notify electric utility
company. If connected to alternate power source such as generator or inverter, make sure the line volt-
age frequency supplied by the device is 60 Hz.
Fault Code FLU
This display indicates that there is excessive flue pressure. This code will reset automatically after the
high pressure condition is resolved. The second line indicates the status of the pump.
Remedy:
1. Assure that the flue is not blocked.
2. Check the switch wiring by applying a jumper in place of the switch. If the code clears with the jumper
in place, REPLACE the flue switch and connect the wires to the new switch BEFORE running unit.
Do not use a jumper to remedy this error. A faulty switch MUST be replaced. Failure to do so
could result in serious injury or death.
Fault Code LEO
This display indicates that there is a low water level in the main tank. This code will not allow the unit to
run until correct water level is restored. The second line indicates the status of the pump. Note: While the
water level is low, the pump will be off.
Remedy:
1. Assure that there is adequate pressure and flow from the cold water inlet by slightly opening the drain
valve near the tank.
2. Assure that the DHW system has all air removed through a high point hot water source, i.e. sink or
shower.
3. Check wiring.
4. Check probes. Replace if necessary.
