  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.

  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.

Why is my Baxi Boiler flashing 2 red lights indicating high temperature protection?

  If your Baxi Boiler is showing 2 red flashes, it indicates high temperature protection activation. This can happen if the over-temperature thermostat on the heat exchanger has been activated, there's no water flow through the heat exchanger, there's a fault or bad connection with the over-temperature thermostat, the PCB is experiencing an over-temperature condition, or there's a flue fault. To resolve this: * Check the connections and operation of the O/T thermostat and air pressure switch (if fitted), as well as the PCB and the condition of the wiring loom. * Ensure the system pressure is correct and that the system is not air-locked. * Verify the pump is operating correctly and the system is circulating water. * Inspect the flue for any issues.
