What does this fault that appears in the Domusa boiler mean?

Oh no! Has the error code 09 appeared on your Domusa boiler and now you don't know what to do? Well, don't worry, because today we're going to explain to you what this error means, what could be its possible causes, and how you can quickly and easily solve it.

Domusa boilers are high efficiency and safety equipment, but like any electronic device, they can experience some faults or breakdowns. One of the most common errors that can appear on boilers of this brand is the error code 09. This error indicates that the burner does not ignite, most likely due to a problem with the gas supply. This can be due to several reasons, such as:

• You don't have a gas service activated: You may have forgotten to pay the bill, there may be a breakdown in the distribution network, or the shut-off valve may be closed.
• There is a problem with the gas pipes: There may be a leak, an obstruction, a poor connection, or even air bubbles that prevent the gas from passing correctly to the boiler.
• A problem with the ignition electrode: This is the component that generates the spark that ignites the gas. If it is very dirty, damaged, or improperly placed and calibrated, it may fail and cause errors in the boiler.
• A faulty gas valve: This is the piece that regulates the flow of gas to the burner. If it is defective, stuck, or improperly adjusted, it can prevent the gas from reaching correctly and cause problems.

All of these causes can cause this fault to appear on the screen of your Domusa boiler. However, you don't have much to worry about because this problem can be solved and we're going to explain how to do it.

How can the error code 09 of the Domusa boiler be solved?

Here's a list of possible solutions for you to try to fix error code 09 on your Domusa boiler. Take note of each one and check them all very carefully, step by step and thoroughly:

1. Turn off and disconnect the boiler from the power supply to reset and refresh its sensors: This may help the boiler detect gas again and ignite smoothly, as this procedure helps to refresh the sensors. To do this, completely turn off the boiler and disconnect it from the power supply for a few minutes. Then, reconnect it, turn on the boiler, and check if the error has disappeared. If the problem persists, then keep reading, as we're sure you'll find the solution with us.
2. Check that you have the gas service activated and fully operational: Check your latest billing and make sure everything is up to date and paid. Call the company that supplies your gas or check for any notices of cutoff or incidents in your area. Check your gas supply, and if the shut-off valve is closed or half-open, fully open it. Once you have resolved the gas issue, please check if the fault in your Domusa boiler has disappeared.
3. Check that the gas pipes are in good condition: Check for any leaks, obstructions, or poor connections that may affect the gas supply. If you detect any problems, close the gas shut-off valve and contact a qualified professional. Check the entire pipe thoroughly, the joints, and connections, and make sure there are no leaks in the entire circuit. It is important that if the pipes do indeed have a leak, you fix the problem as soon as possible because it could be dangerous for you and your family, as a leak could trigger a fire.
4. Check that the ignition electrode is clean and properly positioned: Clean with a dry cloth or fine sandpaper any dirt or residue that may prevent contact with the gas. Also, make sure this electrode is properly connected and secured to the boiler. If you see it broken, worn, or misaligned, it may prevent gas combustion and generate the error code on your Domusa boiler. If necessary, replace the burner with a new one or adjust and calibrate it properly following the manufacturer's Domusa manual instructions.
5. Check that the gas valve is functioning correctly: If the valve is damaged or does not open correctly, it may prevent gas from reaching the burner and cause obvious problems in your Domusa boiler. Check for any signs of wear, breakage, or blockage that may prevent its opening and closing. Also, adjust the gas pressure according to the manufacturer's instructions.
6. If the problem persists, please repeat all the previous steps and make sure to follow everything to the letter: It may be necessary to repeat the solutions we mentioned earlier to completely eliminate this fault present in your Domusa boiler. Therefore, we recommend that you be patient and persistent, and follow all the instructions but this time with more care and attention to detail. If the problem still persists, then it may be time to leave the problem in the hands of experts in Domusa boilers.
7. Call a Domusa technical service and request a home visit for a more thorough inspection: If after trying all the above solutions the problem persists in your boiler, then there may be a more complicated problem to solve that requires the intervention of a qualified professional. In that case, you can contact the Domusa technical service and request a home visit for their authorized personnel to check your boiler and repair it if necessary.

In summary, error code 09 on Domusa boilers means that the burner does not ignite, probably due to a problem with the gas supply.
