How to fix error E.04.15 on REMEHA Gas 220 Ace 300?
If your REMEHA Boiler displays error code E.04.15, it indicates that the flue gas outlet is blocked. To resolve this, check that the flue gas outlet is not blocked and restart the boiler.
What does error E.04.02 mean on a REMEHA Gas 220 Ace 300 Boiler?
If your REMEHA Boiler displays error code E.04.02, it indicates that the flow temperature sensor is open. This may be due to a bad connection, so check the wiring and connectors. If the wiring is intact, the sensor itself may be faulty and require replacement.
What does error E.04.12 on my REMEHA Gas 220 Ace 300 mean?
If your REMEHA Boiler displays error E.04.12, indicating a false flame signal, it could be due to several reasons. If the burner remains very hot, set the O 2. If ionisation current is measured but no flame should be present, check the ionisation/ignition electrode. A faulty gas valve or ignition transformer may also be the cause, so consider replacing these components if necessary.
Why does my REMEHA Gas 220 Ace 300 Boiler's heat exchanger temperature exceed the maximum operating value?
If your REMEHA Boiler's heat exchanger temperature exceeds the maximum operating value, ensure proper circulation by checking the direction, pump, and valves. Also, verify the water pressure, inspect the heat exchanger's cleanliness, confirm the central heating system is vented correctly, and check the sensors for proper operation and fitting.
What does error E.04.05 mean on my REMEHA Gas 220 Ace 300?
If your REMEHA Boiler displays error code E.04.05, it indicates that the flue gas temperature sensor is open. This could be due to a bad connection, so check the wiring and connectors. It may also be due to an incorrectly fitted sensor, so check that the sensor has been correctly fitted. If these steps don't resolve the issue, the sensor itself may be faulty and require replacement.
What does error E.02.04 mean on my REMEHA Gas 220 Ace 300 Boiler?
If your REMEHA Boiler displays error code E.02.04, which indicates a configuration error, reset CN1 and CN2. See the data plate for the CN1 and CN2 values.
What does error E.00.08 mean on my REMEHA Boiler?
If your REMEHA Boiler displays error code E.00.08, indicating the heat exchanger temperature sensor is open, check the wiring and connectors for bad connections. Ensure the sensor has been correctly fitted. If the issue persists, the sensor may be faulty and need replacement.
What does error A.02.06 mean on my REMEHA Boiler?
If your REMEHA Boiler displays error code A.02.06, it indicates a water pressure warning. The water pressure is too low, so check the water pressure.
Why is my REMEHA Boiler showing error H.03.02, indicating no flame?
If your REMEHA Boiler displays error code H.03.02, it indicates no flame during operation. This could be due to several reasons. First, vent the gas supply to remove any air. Then, check that the gas valve is fully opened and verify the gas supply pressure. Inspect the operation and setting of the gas valve unit. Ensure that the air supply inlet and flue gas outlet are not blocked, and check for any recirculation of flue gases.
How to troubleshoot error code E.04.13 on a REMEHA Gas 220 Ace 300?
If your REMEHA Boiler is showing error code E.04.13, it indicates a fan fault. Begin by checking the wiring and connectors for any bad connections. If the fan is operating when it should not be, check for excessive chimney draught. If these steps don't resolve the issue, the fan itself may be faulty and require replacement.
