Hermann Boilers Error 01

What does this failure affecting the Hermann boiler want to tell us?

Gas boilers are household appliances that are essential for keeping our home warm and comfortable. But occasionally they can present errors and problems that leave us extremely worried because we need to use them and simply cannot. One of these problems, and one of the most common, is the error code E1. Today, we're going to explore the causes behind this issue and provide you with practical solutions to resolve it.

The issue that arises with this error in Hermann boilers indicates that the burner has not ignited correctly or that the combustion is incorrect, causing the flame to unexpectedly go out. This fault can affect both hot water production and home heating. Fortunately, there are measures we can take to fix it, but first, we need to understand the causes behind it.

A gas supply failure: If the boiler does not receive enough gas, it will not be able to ignite correctly. Check that the gas supply is active and that there are no supply cut problems.

Issues with the fan or gas valve: A defective fan or a clogged gas valve can cause this fault in your boiler. You need to inspect and clean these components if necessary.

A dirty or damaged airflow sensor: The airflow sensor can accumulate dirt over time, affecting its operation. Clean or replace it according to the manufacturer's instructions; perhaps preventive maintenance is sufficient to fix this fault.

A fault in the boiler's PCB electronic board: In this case, you can check it yourself if you have knowledge of electronics. However, in more serious cases, the boiler's electronic board may be damaged, requiring a just and necessary replacement.

These are the causes that can lead to this fault appearing in your home's boiler, and you may not be able to do anything to prevent it. But you don't have much to worry about; today, we bring you the solution to this problem. Let's see it!

Can a solution be found for error code 01 in the Hermann boiler?

We have prepared a list of possible solutions that can be used to fix this problem that affects your Hermann boiler. You can follow these steps below and give your boiler a definitive fix to restore comfort and well-being in your home:

1. Turning off and unplugging the boiler to reset its sensors can solve the problem: A super easy and simple procedure that you should try first. This step involves turning off your boiler completely and unplugging it from the power outlet for a few minutes. Wait for about 15 minutes and reconnect your boiler to check if the procedure has worked. Turn on your boiler and please check if the error has disappeared. If you have not succeeded, then proceed with the following steps we have outlined below.
2. Check that your gas supply is activated and working normally: Without gas, your boiler simply will not work, so you need to make sure that the gas is flowing correctly throughout your boiler's heating circuit. Take the opportunity to also check that the valve is open, the shut-off valve, and that the pipes do not have any obstructions that could prevent the free flow of gas to the appliances that may need it. If possible, turn on any other gas-fueled appliance to rule out that it is not a specific problem with your boiler.
3. Perform preventive maintenance on your boiler and clean the airflow sensor: If you have already ruled out the possibility that the problem is a gas supply failure, then consider performing preventive maintenance on the boiler and cleaning all sensors, especially the airflow sensor that could be causing the fault. Follow the manufacturer's manual instructions and check what it indicates about this type of scheduled maintenance. Also, check that the fan is in good working condition, clean, and can rotate freely. If you find that any sensor is in poor working condition, then you will need to replace it with a new one that is compatible with your Hermann boiler model.
4. Check the PCB electronic board with a multimeter and rule out possible faults: If you have advanced knowledge in electronics, then it's time to make use of it. Use a multimeter and check carefully that all components of the PCB electronic board of your boiler are operational. It may be the case that some components such as resistors or capacitors end up burning out and not performing their function as they should, causing these types of faults in your boiler. You can try to replace the damaged components or replace the entire electronic board by getting a new one that is compatible with your Hermann boiler model. If you feel that this is too complicated, don't worry, it is for us too, in which case it would be best to seek help from technical support.
5. Do a brief review of everything we have mentioned earlier in this article: If the problem persists in your boiler and you have not been able to solve it, then we recommend doing a brief review of all the steps we have described. Make sure you have followed everything to the letter, also make sure you have not skipped any steps and check that everything is in perfect and optimal condition. If nothing seems to find the solution, then let's leave the matter in the hands of boiler experts.
6. A qualified professional or Hermann technical support can help you solve this problem: Without a doubt, a boiler expert qualified by the Hermann company can help you fix this fault affecting your boiler. Make a call to Hermann's technical support and arrange a home visit for your boiler inspection. We are confident that they have the necessary tools and knowledge to deal with this situation.

In summary, the E1 error code in Hermann brand boilers can be due to problems in the gas supply, damaged or poor components, a lack of preventive maintenance and/or dirt on the sensors, as well as a failure in the electronic card that controls the boiler. To give an immediate solution to this problem, you will have to follow the steps that we have indicated in this small advice guide.

We hope to have been very helpful to you today. Remember that preventive maintenance is always appropriate to prevent this type of situation from occurring in your boiler and you can continue enjoying a warm atmosphere in your home or office. Until next time!
