When your heating system breaks down, it often happens at the worst possible times: in the middle of winter, when you get home, or just before a visit. If you use an Atlantic Naema or Naia boiler, this article helps you detect, understand, and resolve the most common faults, while also guiding you on how to contact a professional if necessary. 1. My boiler stops or no longer heats: what should I check? Heat stops: consider the hydraulic circuit A sudden stoppage of the heating system may be due to a fault in the heating circuit or poor water circulation. Check: The condition of the circulator or pump; Bleeding the radiators to release accumulated air;The proper functioning of the valve and the pressure in the circuit. A faulty pressure sensor can also prevent restarting. If an error 104 or 132 is displayed on the screen, this may indicate a problem with the burner, the sensor, or the combustion system. Power outage or electrical problem?A power outage, a micro-outage, or an internal electrical fault can disable the system. If nothing restarts after a few minutes, turn the unit off and then back on. If the error persists, it’s best to call a professional. Discover the AP code for the Naia/Naéma boiler, an innovative solution for your thermal comfort. Learn about its features, benefits, and usage tips to optimize your installation. 2. My boiler is displaying an error (104, 132, 128, AP, etc.): what do these codes mean? Naema and Naia wall-mounted condensing boilers are equipped with an intelligent diagnostic system. Here are the most common errors: Error 104: Burner ignition problem, flame sensor or electrode fault; Error 132: Combustion fault, gas accumulation, or faulty temperature sensor; Error 128: Water in the circuit Insufficient or undetected;
AP: Water pressure problem, level too low, or faulty pressure sensor.
These faults may be caused by a worn component or a problem with the gas equipment. It is essential to perform a quick diagnosis to ensure the safety of your home.
3. Heating or hot water problem: what is the role of the internal components? Your boiler relies on several key components to produce heat and heat domestic water: The heating element and the exchanger transfer energy; The Navilink modulating thermostat adjusts the temperature according to your needs; The temperature and pressure sensors monitor the system’s status; The heating element and the burner ensure gas combustion. If any of these components are dirty or faulty, this can impact the heating quality in your rooms or cause the appliance to shut down completely. 4.
