Check whether the 10A fuse on the circuit board is open. Check the 15V ouput line form the power (source circuit board.) Input voltage measurement of a C.B.A. Check voltage supply from circuit board to remote controller. Check for open or short circuit.
Check maintenance monitor no. 15
Check inlet water temperature Check if high-limit switch is triggered or improperly connected.
Check the resistance through the thermistor. Check for open or short circuit,or improper connection. Check the resistance through the thermistor. Check for open or short circuit,or improper connection. Check the resistance through the thermistor. Check for open or short circuit,or improper connection.
Check remote controller and circuit board. Check connection of remote control cord and cord to circuit board.
Remove the cause of excess current, then replace the 10A fuse. If there is AC 120V supplied to the power source circuit board, but there is not
DC 15V out of it, the power source circuit board needs to be replaced. Check for improper or damaged connections between the two boards, and for an open circuit on the circuit board. If voltage is abnormal, replace circuit board. If there is an open or short circuit, or a ground fault is detected, replace the cord.

A blinking 10 indicates there has been a loss of gas input, but combustion will continue. In order to reset the unit, the power must be disconnected and then reconnected.
If the overheat prevention device (Thermal fuse) has fused, it has been exposed to temperatures in excess of 363F.First fix the cause of the high temperature exposure (hole in
heat exchanger, etc.) and then replace the overheat prevention device
(Thermal fuse).
If there is a voltage abnormality, replace the circuit board.
Compare to temperature characteristic list on pg. 17. Check for open or short circuit or for an improper connection. Compare to temperature characteristic list on pg. 17.

If the flow monitor indicates higher than the minimum, the circuit board will need to be replaced.
OK if K > 28.5/Flow Rate (GPM) + inlet water temp (°F), where K = 136°F for 127°F or lower temperature setting, K= Set Temp (C) + 18°F for 127°F or more
setting. Also check thermistor temperature characteristics.
Make Sure there is no flame left over in the burner. Check for short or open circuit. Reset unit by turning power off and on. Replace high-limit if code remains.
less than 122°F using
thermistor characteristics
If abnormal combustion is detected,the error code will flash and combustion stops.
This error code can be reset by turning the water heater OFF on the operation panel. Remove the cause of the abnormal combustion.
If an open or short circuit or a ground fault exists, replace Remote Control cord.
If this error code is displayed and the water heater has been in use for 10 years, the unit has reached the end of its life cycle and should be replaced.
Check for abnormal combustion. Check flue and air inlet for blockage or obstruction.
Check for abnormal combustion. Check flue and air inlet for blockage or obstruction.
Check remote control cord for a short or open circuit, or for a ground fault.
Check for abnormal combustion. Check flue and air inlet for blockage or obstruction. Check for melting or improper
connection of the overheat prevention device (Thermal fuse).
Check maintenance monitor No.48. If the fan has increased its speed by 108 -
109 %, the error code will flash but combustion continues. If the fan has increased
its speed by 110 %, the error code will flash and combustion stops.
