(ESM) ERROR CODE INDICATES CORRECTIVE ACTION*
E01 with an alert Icon flashing. Dry-fire, electrical power on with the tank not
completely full of water. 1. Turn off electrical power at breaker, add water.
2. Turn on electrical power at breaker.
3. See “Water Heater Start-Up” on page 10.
E02 with an alert Icon flashing. Water temperature exceeded high limit. 1. Turn off electrical power at the breaker.
2. Press the reset button (see Figure 10A).
3. Turn on electrical power at breaker.
4. If error returns call a service technician for assistance.
E03 with an alert Icon flashing. Upper thermistor sensor failure.
(Note: Upper thermistor sensor is part of
the ET) 1. Turn off electrical power at the breaker.
2. Replace Electronic Thermostat (ET).
3. Turn on electrical power at breaker.
E04 with an alert Icon flashing. Upper element circuit failure.
(Note: Lower element is still operable) 1. Turn off electrical power at the breaker.
2. Check element circuits for resistance of 5-25 ohms (replace if required).
3. Check wires at elements and Electronic Thermostat (ET) for damage.
If this 4 flashes condition continues, replace Electronic Thermostat (ET).
4. Turn on electrical power at breaker.
E05 with an alert Icon flashing. Lower element circuit failure.
(Note: Upper element is still operable) 1. Turn off electrical power at the breaker.
2. Check element circuits for resistance of 5-25 ohms (replace if required).
3. Check wires at elements and Electronic Thermostat (ET) for damage.
If this 5 flashes condition continues, replace Electronic Thermostat (ET).
4. Turn on electrical power at breaker.
E06 with an alert Icon flashing. Electronic Thermostat (ET) failure
(Internal processor). 1. Turn off electrical power at the breaker. Now turn on electrical power to
see if error clears. If error has not cleared, replace Electronic Thermo-
stat (ET).
2. Turn on electrical power at breaker.
E07 with an alert Icon flashing. Lower thermistor sensor failure. 1. Turn off electrical power at the breaker.
2. Check electrical connections at Electronic Thermostat (ET).
3. Replace Lower Thermistor Sensor.
4. Turn on electrical power at breaker.
E08 with an alert Icon flashing. Energy Smart ® Module (ESM)
failure.
1. Turn off electrical power.
2. Check wires at the interface module for damage.
3. If this 8 flashes condition continues, replace module (ESM).
4. See “Overriding The Interface Module (ESM)” by unplugging from the
Electronic Thermostat (ET) on page 12. NOTE: Electronic Thermostat
(ET) will continue to be operate, hot water will still be available.
5. Turn on electrical power at breaker.
E09 with an alert Icon flashing.
E10
E11
E12
Electronic Thermostat (ET) error. 1. Turn off electrical power.
2. Check wiring at Electronic Thermostat (ET) for damage.
3. Turn on electrical power at breaker.
4. If this code flashes condition continues, replace the Electronic
Thermostat (ET).
IMPORTANT: Before attempting to adjust the ther-
mostat, read the “Water Temperature Regulation”
section page 10.
The Electronic Thermostat (ET) is designed so
that it may control the water heater without the
Energy Smart
® Module (ESM) being operated,
see page 12.
