Lack of Hot Water?

One of the most frequent issues homeowners encounter with Baxi Combi Boilers is a lack of hot water. This problem can stem from various causes.  Including a faulty diverter valve, a malfunctioning thermostat, or a water pressure imbalance. Therefore, to address this issue, it is advisable to check if the boiler is receiving adequate water pressure.  Also, to ensure the valve is functioning correctly.  Then consider consulting a certified technician for a thorough inspection.


Boiler Not Igniting?

Another common concern is when the Baxi Combi Boiler fails to ignite or experiences intermittent ignition problems. This can be due to a faulty ignition system, gas supply issues, or blocked burner jets. As a result of this, to resolve the issue, it is recommended to check the gas supply.  Also ensure it is not interrupted, ensure also the ignition leads and electrodes are clean and properly connected.   Moreover, seek professional assistance if needed.


Unusual Noises?

Some Baxi Combi Boiler owners may also notice strange noises emanating from their heating system. These noises could be caused by air trapped within the boiler’s pipes, a weakening pump, or a faulty heat exchanger. In such cases, it is best to bleed any trapped air from the system.  Moreover, check the pump’s functionality and lubrication, and consult an expert plumber or technician for further diagnosis and assistance.


Pressure Fluctuations?

Fluctuations in boiler pressure are another concern encountered by Baxi Combi Boiler users. This problem can arise due to water leaks, faulty pressure relief valves, or issues with the expansion vessel. As a result of this, addressing this issue involves inspecting the system for visible leaks.  Also ensuring the pressure relief valve is functioning correctly.  Furthermore consulting a professional to assess the condition of the expansion vessel and its pressure settings.

    I have a Baxi luna 3 comfort.
    Central heating is fine.
    Heat exchanger cleaned last year.
    My problem is DHW is set at 60 oC but it won’t get past 42 oC at taps.
    I live in Bulgaria so any pointers would be greatly appreciated.
