CA Air in the water circuit (commissioning).
Water flow above maximum value specified
(

9.24GPM).
▶ Disconnect the appliance and purge hydraulic
circuit.
1)
▶ Install water flow restrictor.
1)
▶ Check water pressure does not exceed 150 psi.

- Vent blockage during operation (Flue vent outlet
or air vent inlet). Insufficient combustion air.
- Air flow insufficient for start-up (Before flame
ignition).
- Flue outlet vent blockage (exhaust pressure
above siphon water column). Excessive flue vent
pressure. ▶ Remove blockage from the exhaust/intake vent.
▶ Check room air inlet requirements. See chapter
4.6.6.
▶ Reset the appliance.
C3 Flow sensor does not detect water recirculation. ▶ Check pump and connections.
▶ Check recirculation circuit for any blockage.
E0 Internal failure on ECU. ▶ Reset failure by long press (3sec.) on ON/FF
button.
▶ If the problem persist replace ECU.
1)
E1 Hot water temperature sensor detects overheating
(> 194 °F). ▶ Let the appliance cool down and try again.
▶ Check sensor resistance.
1)
E3 Flue gas temperature sensor detects high
temperature (> 194 °F). ▶ Let the appliance cool down and try again.
1)
▶ Check sensor resistance.
1)
E4 Temperature inside the cabinet is above 194 °F. ▶ Check for flue gas leakage inside the cabinet.
▶ Let the appliance cool down and try again.
1)
▶ Check sensor resistance.
1)
E5 Copper heat exchanger gas temperature sensor
detects temperature above 392 °F, the appliance
is locked. ▶ Descale appliance.
1)
E7 Internal error ▶ To unlock, reset the appliance by touching the
ON/OFF button for 3 sec.
▶ If the problem persist replace ECU.
1)
E8 Error during ionization test. ECU internal error. ▶ ECU may need to be replaced.
E9 Thermofuse open.
Temperature above 237 °F. ▶ Replace thermofuse cable.
EA Flame not detected.
Ionization loss 9 consecutive times. ▶ Check the gas supply pressure.
▶ To unlock, reset the appliance by touching the
ON/OFF button for 3 sec.
▶ If the problem persist check the ignition electrode
or the ionization electrode.
▶ Check Air/Gas flow adjustment.
EC Partial ionization loss 5 times. ▶ Check the gas supply pressure.
1)
▶ To unlock, reset the appliance by touching the
ON/OFF button for 3 sec.
▶ If the problem persist check the ignition electrode
or the ionization electrode.
EE Modulating gas solenoid valve disconnected. ▶ Check valve connection.
