Why is my Baxi EcoBlue Advance Heat 19 Boiler flashing 1 red light indicating a sensor error?

  If your Baxi Boiler displays 1 red flash, it indicates a sensor error. This could be due to a bad connection to the flow or return temperature sensor, a fault with the temperature sensors, low or no flow through the boiler, or reverse flow through the boiler. To address this: * Check the connections to the temperature sensors/PCB and the condition of the wiring loom. * Check the resistance of the temperature sensors. * Check the pump operation and system circulation.

What to do if my Baxi EcoBlue Advance Heat 19 Boiler shows 3 red flashes for an ignition fault?

  Nichole BrownAug 20, 2025
  If your Baxi Boiler displays 3 red flashes, indicating an ignition fault, several issues could be the cause. It might be due to no ignition, no flame detected after ignition, a false flame signal, or repeated flame loss. To address this, you should: * Verify the appliance is properly earthed. * Inspect the ignition electrode, cleaning or replacing it if needed. * Check the operation of the gas valve. * Ensure the flue is in good condition. * Verify the combustion and gas valve settings are correct. * Inspect the condensate drain for any blockages.
