¡Aha! We know you have a Domusa boiler and that you're currently experiencing an issue with it! And no, we're not mind readers or fortune tellers, it's just that if you're reading this article, it's obviously because you have a problem with the device and you're hoping to resolve it soon. Well, you've come to the right place for that.

When your Domusa boiler displays the error code 07, it can be a frustrating moment for you. This fault is a cry for help from your boiler, indicating that something is amiss in its internal communication system. But don't worry, we'll explain what it means and how you can fix it.

This problem affecting Domusa brand boilers is related to communication failures between components of the boiler. This can be due to a variety of causes, from a simple loose wire to a defective sensor. Identifying the exact cause can be tricky, but it's the first step to solving the problem. So let's get to it!

• Faulty wiring: A loose or damaged wire can interrupt communication between components, causing not only this error on the screen, but any other that may be just as problematic.
• Sensors not functioning correctly: Sensors provide vital information that is sent to the boiler's electronic card. If these sensors fail, the boiler won't be able to operate correctly.
• Defective PCB (Printed Circuit Board) or electronic card: This component is the "brain" of your boiler, so if it malfunctions, then you have a serious problem with the device.

Now that you know the causes that lead to this problem, let's see what solutions you can apply to fix it.

How could the error code 07 of the Domusa boiler be solved?

We are going to leave you here a list of solutions so that you can fix this failure sooner rather than later. Do not be discouraged because this error has appeared to you, there may be a solution and you just have to try it. Let's go!

1. Turn off and disconnect the Domusa boiler from the power source to reset the sensors: As a first step, turn off and disconnect the boiler from the power source for about 15 minutes. This can reset the system and eliminate temporary errors, as the sensors are reset. As we mentioned earlier, one of the possible causes is faulty sensors, and with this reset procedure, we can rule out any temporary error affecting your Domusa boiler.

If you find corrosion on the connections, then you will need to perform a brief maintenance to remove it completely.
3. Check the sensors of your Domusa boiler if you have electronics knowledge: Test the operation of the sensors with a multimeter. Visually inspect them, and if any appear faulty, they may need to be replaced with new ones compatible with your model of Domusa boiler. It's important that the sensors function correctly so they can send accurate information to the electronic card, allowing the device to operate without any issues.
4. Inspect the PCB (Printed Circuit Board) of your Domusa boiler with a multimeter and rule out damaged components: Thoroughly visually inspect the electronic board of your boiler. Confirm that there are no bulging or exploded capacitors, signs of burns, loose or corroded connections, etc. In other words, ensure that it is in excellent operating condition. Take advantage of conducting a second comprehensive inspection with a multimeter on all the wiring of this card, as well as its components. If this card is definitely damaged, then it will need to be replaced with a new one compatible with your model of Domusa boiler.
