Error Code
Error Code Description
Possible Remedies
Er:30
Recirculation Sensor
Fault
This Error Code will go away when inlet water temperature decreases.
If Error happens again:
1. Check recirculation water temperature sensor. Ensure connections are secure.
2. Check sensor resistance. If resistance is zero, replace the sensor.
3. If the problem persists, replace the main control.
Er:31
Water Inlet Sensor Open
or Short
This Error Code will go away when inlet water temperature decreases.
If Error happens again:
1. Check inlet water temperature sensor. Ensure connections are secure.
2. Check sensor resistance. If resistance is zero, replace the sensor.
3. If the problem persists, replace the main control.
Er:32
Water Outlet Sensor
Open or Short
This Error Code will go away when outlet water temperature decreases.
If Error happens again:
1. Check DHW outlet temperature sensor. Ensure connections are secure.
2. Check sensor resistance. If resistance is zero, replace the sensor.
3. If the problem persists, replace the main control.
Er:33
H/X Temperature Sensor
Open or Short
This Error Code will go away when outlet water temperature decreases.
If Error happens again:
1. Check operating temperature sensor. Ensure connections are secure.
2. Check sensor resistance. If resistance is zero, replace the sensor.
3. If the problem persists, replace the main control.
Er:35
Exhaust Sensor Open or
Short
This Error Code will go away when exhaust temperature decreases.
If Error happens again:
1. Check exhaust temperature sensor. Ensure connections are secure.
2. Check sensor resistance. If resistance is zero, replace the sensor.
3. Check exhaust vent for blockage.
4. If the problem persists, replace the main control.
Er:37
Abnormal Supply
Frequency
Supply frequency is too high to operate. This Error Code will go away when supply frequency returns to
normal operating range.
If Error happens again:
1. Ensure appliance is properly wired to a power source meeting the requirements on the rating plate.
2. If problem persists, replace the main control.
Er:38
Error Appears When
Control Stores Data, but
Data is not Saved
Press the Power button to clear the Error Code.
Replace the main control.
Er:40
Gas Leakage is Detected
in 10 Minutes, or three
times within One Hour

Each Time)
IMPORTANT:
If you smell gas, STOP! Follow the instructions on page 2, this manual, and call a
qualified service technician or the fuel gas utility.
Press the Power button to clear the Error Code.
If Error happens again:
1. Check the water heater cover. Ensure it is secure.
2. Check gas connections for leakage with a soapy solution. Fix any leaks.
3. Check condition of the burner assembly.
4. If the problem persists, replace the main control.
Er:41
Fan Speed too High with
Flame On
Press the Power button to clear the Error Code.
If Error happens again:
1. Check the vent connections for blockages.
2. Check the burner assembly.
3. Check fan operation. If fan appears to be operating normally but RPMs are too low or too high,
replace the fan.
4. If the problem persists, replace the main control.
Er:42
Jumped Wire
Disconnected
Press the Power button to clear the Error Code.
If Error happens again:
1. Ensure the jumped wire is properly connected.
2. If the problem persists, replace the main control.
Er:43
Burner Overheat Switch

Press the Power button to clear the Error Code.
If Error happens again:
1. Check burner overheat switch connections. Ensure connections are secure.
2. Check switch resistance. If resistance is not zero, replace the switch.
3. If the problem persists, replace the main control.
Er:44
APS Fault
(Intake or Exhaust)
Press the Power button to clear the Error Code.
1. Check APS and main controller connections. Ensure all are secure.
2. Check APS hose. Ensure it is connected and in good condition.
3. Check condensate line and termination for blockages.
4. Check exhaust vent for blockages.
5. If the problem persists, replace the main control.
Er:45
APS
– Closed is Normal,
Open is Fault
(Condensate Drain Trap)
Er:61
Fan Speed Feedback
Signal Abnormal
This Error Code will go away when the condition is remedied.
If Error happens again:
1. Check the connections to the fan. Ensure all are secure.
2. If the fan does not rotate during the ignition sequence, check for 120V power at the fan connection. If
120V power is present at the control, replace the fan. If the blower does not have 120V power, check
power at the control. If 120V power is not present at the control, replace the control.
3. If the problem persists, replace the main control.
