J. ERROR MODE
When the water heater encounters an error, the d
isplay will flash “Er” followed by a numerical code. The water heater shall enter a soft
lockout condition if the error is such that it can return to normal operation once the condition relieves itself (overheat conditions, NTC
open or shorts, etc.). The water heater shall enter a hard lockout if the condition indicates something more serious (flame, ignition,
condensate line, etc.) To clear a hard lockout Error Code, press the Power button. See Figure 50 B.
The following screen will display when the water heater encounters an error.

Error Code Error Code Description Possible Remedies
Er:10
Flame has Extinguished
5 (Five) Times
Press the Power button to clear the Error Code.
If Error happens again:
1. Monitor the gas pressure to the water heater while in operation. Ensure pressure is between 3.5 and
14” WC.
2. Check gas valve wire. Ensure connection is secure.
3. Check flame detection sensor. Ensure connections are secure. Normal operating settings are more
than 2.5DC before ignition, less than 2.5DC after ignition.
4. Check vent terminations. Ensure there are no blockages.
5. Assure that the flame is stable when lit.
6. If the problem persists, replace the main control.
Er:11
Ignition has Failed 5
(Five) Times
Press the Power button to clear the Error Code.
If Error happens again:
1. Monitor the gas pressure to the water heater while in operation. Ensure pressure is between 3.5 and
14” WC.
2. Check gas valve wire. Ensure connection is secure.
3. Check flame detection sensor. Ensure connections are secure. Normal operating settings are more
than 2.5DC before ignition, less than 2.5DC after ignition.
4. Check igniter transformer for proper connection.
5. Clean the spark igniter with steel wool to remove oxides. Ensure proper separation (3-4 mm).
6. Replace the spark igniter if damaged.
7. Assure that the flame is stable when lit.
8. If the problem persists, replace the main control.
Er:16
Operating Temperature
Sensor Detects Water
Temperature Greater
than 199
o
F (93
o
C)
This Error Code will go away when the DHW temperature decreases.
If Error happens again:
1. Check if dip switch High Fire setting is ON. Switches 6 and 7 should be OFF for normal operation.
2. Check if DHW pipe is blocked. Ensure there is enough water flowing to the water heater.
3. Check DHW sensor at DHW outlet. If resistance is zero, replace the sensor.
4. Check Operating Temperature sensor at the heat exchanger. If resistance is zero, replace the
sensor.
5. If the problem persists, replace the main control.
Er:20
Temperature High Limit
Overheat Switch
–
Closed is Normal, Open
is Fault
Press the Power button to clear the Error Code.
1. Inspect the High Limit Overheat switch. Ensure proper connections.
2. Check High Limit Overheat switch resistance. If resistance is not zero, replace the switch.
3. If the problem persists, replace the main control.
Er:28
Overheat Sensor Open
or Short
This Error Code will go away when CH temperature decreases.
If Error happens again:
1. Check overheat temperature sensor. Ensure connections are secure.
2. Check overheat sensor resistance. If resistance is zero, replace the sensor.
3. If the problem persists, replace the main control.
Er:29
APS/Condensate
–
Closed is Normal, Open
is Fault (Condensate
Drain Trap)
Press the Power button to clear the Error Code.
1. Check APS/Condensate and main controller connections. Ensure all are secure.
2. Check APS/Condensate resistance. If resistance is not zero, replace the switch.
3. Check APS/Condensate hose. Ensure it is connected and in good condition.
4. Check condensate line and termination for blockages.
5. Check exhaust vent for blockages.
6. If the problem persists, replace the main control.
