How to solve the error 04 of the Biasi boiler?

This error code 04 on Biasi boilers could be considered quite easy to resolve. To fix it, you can follow these steps provided below:

1. Restart the boiler to reset the sensors: This is done by turning off the boiler, disconnecting it from the power supply, and waiting a few minutes before reconnecting it. Turn it back on and check if the error code has disappeared.
2. Check the water supply: Make sure you have a clean and stable water flow to supply this vital liquid to your boiler. If the boiler is not receiving water from your home's supply, then this is likely the cause of the error. Also, ensure that there are no leaks in the hose leading from your supply to the boiler.
3. Inspect for any water leaks in the circuit: Checking for water leaks is crucial when encountering this error code. Verify that there are no leaks anywhere in the water heating circuit. Thoroughly inspect hoses, joints, and all connections. If you find a leak, you'll need to repair it as soon as possible.
4. Check the water pressure in the boiler: The water pressure should be between 1 and 1.5 bar. If it's below this range, open the filling tap until the pressure increases. If it's above this range, open a radiator or a hot water tap until the pressure decreases.
5. Clean the water inlet filter and valves: These components can accumulate dirt, sand, limescale, or something that obstructs the water flow. To clean them, you should shut off the water supply, carefully disassemble them, and clean them with a soft-bristle brush or a damp cloth. You can use warm water and a bit of vinegar to assist with cleaning.
6. Check the pressure sensor and the boiler's electronic board: These components can fail due to a manufacturing defect or overheating. To inspect them, turn off the boiler, disconnect it from the power source, and open the front panel. The pressure sensor is typically located near the pressure gauge and has two connected cables. The electronic board is usually behind the LCD display and has several connected cables. If you see any signs of burning, damage, or disconnection, you'll need to replace them with new ones.
7. Go over everything we've mentioned previously: If the problem persists, repeat the previous steps. Double-check everything, perform secondary inspections, and ensure you follow each step precisely.
8. Seek assistance from Biasi's technical support to resolve the issue: If, after following all the previous steps, the error code 04 continues to appear, it indicates a more serious problem that requires the intervention of a qualified professional. If you've reached this point, it's time to call Biasi's technical service and schedule an in-depth inspection of your boiler.
