What does 2 green flashes mean on Baxi Boiler?
Two green flashes on your Baxi Boiler indicate that the BL terminals on the HMI are open circuit. If a condensate pump is wired to these terminals, check its operation. Also, check the wiring to the BL terminals to ensure the link is present or connections to the external device are correct.
Why is my Baxi MainEco Heat 15 flashing 1 red?
A single red flash on your Baxi Boiler indicates a potential issue with the temperature sensors or water flow. Check the following: Examine the connections to the temperature sensors/PCB and the condition of the wiring loom. Verify the resistance of the temperature sensors. Ensure the pump is operating correctly and that there is proper system circulation. Low or reverse flow through the boiler can also cause this issue.
Why is my Baxi Boiler flashing 3 green lights?
If your Baxi Boiler is flashing 3 green lights, it means no flame was detected during operation. Check that the gas supply is turned on and available, especially if you're using a pre-payment meter. Also, check the flue condition.
How to fix 1 flash green on Baxi MainEco Heat 15?
If your Baxi Boiler displays 1 green flash, it means that the maximum flow temperature has been exceeded, the flow temperature rise rate is too high, or there's an excessive difference between the flow and return temperatures. You should check the system circulation and pump operation, check demands for boiler operation, check the temperature setting and check the temperature sensors in the boiler.
What to do if my Baxi MainEco Heat 15 is showing 2 flashes red?
If your Baxi Boiler shows 2 red flashes, it means the over-temperature thermostat on the heat exchanger has been activated, there's no water flow through the heat exchanger, the over-temperature thermostat is faulty or has a bad connection, there's a PCB over-temperature condition, or there's a flue fault. To resolve this: * Check the connections to and operation of the O/T thermostat and air pressure switch (if fitted) and PCB and condition of wiring loom. * Check the system pressure and ensure the system is not air-locked. * Check the pump operation and system circulation. * Check the flue condition.
What to do if my Baxi MainEco Heat 15 flashes 4 green?
Four green flashes on your Baxi Boiler may indicate a bad connection, wiring fault, or internal communication fault. Check the wiring and connections between the boiler, User Interaction Controller, and box. If necessary, replace the control/fan assembly.
What does 3 green flashes mean on Baxi MainEco Heat 15?
Three green flashes on your Baxi Boiler indicate that no flame was detected during operation. Ensure that the gas supply is turned on and gas is available, especially if you are on a pre-payment meter. Also, check the flue condition.
How to troubleshoot 1 green flash on Baxi MainEco Heat 15?
One green flash on your Baxi Boiler suggests an issue with the flow temperature. Check the system circulation and pump operation. Also, check the demands for boiler operation, such as switched live operation. Verify the temperature setting and inspect the temperature sensors in the boiler.
What to do if Baxi Boiler shows 5 flashes green?
If your Baxi Boiler displays 5 green flashes, it indicates a parameter error, a faulty PU, a configuration error, or a PCB fault. Replace the PU and recommission. You might also need to replace the control/fan assembly.
How to solve 6 flashes red on Baxi MainEco Heat 15?
If your Baxi Boiler is showing 6 red flashes, it indicates a bad connection or wiring fault (internal or external to the boiler), a parameter error, or a communication error. Check that all wiring connections are correctly made. Using a service tool or Recom software, check all parameter settings. If necessary, replace the PU and/or control/fan assembly.
