Why does my REMEHA Boiler show a 5x Error of unintended Flame Loss occurrence?
- D
  David CollierAug 26, 2025
  If your REMEHA Boiler shows a 5x Error of unintended Flame Loss occurrence, it could be due to: * Low ionization current: Vent the gas supply to remove air. * Gas valve issues: Ensure the gas valve is fully opened and check its operation and setting. * Gas supply problems: Check the gas supply pressure. * Blockages: Verify that the air supply inlet and flue gas outlet are not blocked. * Flue gas recirculation: Ensure there is no recirculation of flue gases.

What causes a low ionization current in my REMEHA Quinta Ace 65?
- S
  Sabrina SnyderAug 26, 2025
  If the measured ionization current is below the limit in your REMEHA Boiler, consider the following: * No flame during operation: Vent the gas supply to remove air. * Gas valve issues: Check that the gas valve is fully opened, and check the operation and setting of the gas valve unit. * Gas supply pressure: Check the gas supply pressure. * Blockages: Check that the air supply inlet and flue gas outlet are not blocked. * Flue gas recirculation: Check that there is no recirculation of flue gases.

How to resolve flue gas temperature exceeding maximum value in REMEHA Quinta Ace 65 Boiler?
- M
  Marie SandersAug 26, 2025
  If the flue gas temperature has exceeded the maximum operating value in your REMEHA Boiler, you should: * Check the flue gas outlet system. * Check the heat exchanger to ensure that the flue gas side is not clogged. * Replace the sensor.

What causes the maximum difference between flow and return temperature in REMEHA Boiler?
- N
  nhahnAug 27, 2025
  If there is a maximum difference between the flow and return temperature in your REMEHA Boiler, you can: * Check the flow (direction, pump, valves). * Check the water pressure. * Check the cleanliness of the heat exchanger. * Check that the sensors are operating correctly and that the sensor has been fitted properly.

What to do if the flow temperature exceeds the maximum operating value in REMEHA Quinta Ace 65?
- C
  Catherine HolmesAug 27, 2025
  If the flow temperature has exceeded the maximum operating value in your REMEHA Boiler, you should: * Check the circulation (direction, pump, valves). * Check the water pressure. * Check the cleanliness of the heat exchanger.

Why does my REMEHA Quinta Ace 65 fail to start the burner after five attempts?
- C
  Christopher BrownAug 27, 2025
  If your REMEHA Boiler has detected five unsuccessful burner starts, it could be due to: * No ignition spark: Check the wiring between the CU-GH and the ignition transformer, the ionisation/ignition electrode, breakdown to earth, the condition of the burner cover and the earthing. Consider replacing the CU-GH. * Ignition spark but no flame: Vent the gas pipes to remove air. Check that the air supply inlet and flue gas outlet are not blocked, the gas valve is fully opened, the gas supply pressure, the operation and setting of the gas valve unit and the wiring on the gas valve unit. Consider replacing the CU-GH.

What causes the maximum heat exchanger temperature gradient level3 to be exceeded in REMEHA Boiler?
- M
  michaelwilsonAug 27, 2025
  If the maximum heat exchanger temperature gradient level3 is exceeded in your REMEHA Boiler, you can: * Check the circulation (direction, pump, valves). * Check the water pressure. * Check the cleanliness of the heat exchanger. * Check that the central heating system has been correctly vented to remove air. * Check that the sensors are operating correctly and that the sensor has been fitted properly.

Why is the return temperature sensor not detected in my REMEHA Boiler?
- A
  Andre SmithAug 28, 2025
  If the return temperature sensor was expected but not detected on your REMEHA Boiler, check the wiring and connectors. Also, consider replacing the sensor.

What should I do if the return temperature sensor is shorted or reads too high on my REMEHA Quinta Ace 65 Boiler?
- J
  Jeffery HuntAug 28, 2025
  If the return temperature sensor is either shorted or measures a temperature above range in your REMEHA Boiler, you should check the wiring and connectors, ensure that the sensor has been correctly fitted, and replace the sensor if necessary.

What does it mean when the return temperature sensor is removed or reads too low on my REMEHA Quinta Ace 65 Boiler?
- P
  Patrick SmithAug 28, 2025
  If the return temperature sensor is either removed or measures a temperature below range in your REMEHA Boiler, check the wiring and connectors, ensure that the sensor has been correctly fitted, and replace the sensor if necessary.
