Vaillant Ecotec boilers are popular in the UK, known for their reliability and energy efficiency. However, like all boilers, they can experience faults from time to time. One of the most common faults is the F73 fault code. In this blog, we will look at what the F73 fault code is, why it occurs and what steps you can take to fix it.
The F73 fault code on a Vaillant Ecotec boiler means that there is an issue with the gas supply. The boiler will detect a fault in the gas valve or the wiring that controls it. When the boiler detects this fault, it will shut down and display the F73 error code on the display panel.
The F73 fault code can occur due to a number of reasons. The most common cause is a faulty gas valve. The gas valve used in the device is chiefly responsible for taking care of the flow of gas to the burner. If the gas valve is faulty, it will not be able to control the flow of gas, which can cause the boiler to shut down and display the F73 error code.
Another common cause of the F73 fault code is a fault in the wiring that controls the gas valve. If the wiring is damaged or broken, it will not be able to send the correct signals to the gas valve, which can cause the boiler to shut down and display the F73 error code.
If you see the F73 error code on your Vaillant Ecotec boiler, there are several steps you can take to fix the issue. The following are a few things that you can look into:
The first thing you should do is check the gas supply to the boiler. Make sure that the gas supply is on and that there are no issues with the gas supply to your property. You should also check the gas meter to make sure that it is working correctly.
Try resetting the boiler by turning it off and then back on again. This may clear the fault and allow the boiler to start up again. To reset the boiler, you should turn it off at the wall and then wait for a few minutes before turning it back on again.
If the fault persists, you should check the gas valve. The gas valve is located at the front of the boiler and can be accessed by removing the front panel. Check the wiring to the gas valve and make sure that it is connected securely. You should also check the resistance across the gas valve using a multimeter. If the resistance is not within the specified range, the gas valve may be faulty and will need to be replaced.
If the gas valve is not the issue, the fault may be caused by faulty wiring. You should check the wiring that controls the gas valve and make sure that it is not damaged or broken. If you find any defect in the wiring, then you may get it replaced using the services of the experts.
If you are unable to fix the F73 fault code on your own, it is recommended that you call a professional heating engineer. They will have the knowledge and experience to diagnose and fix the fault. They will also have access to the necessary tools and equipment to carry out the repairs safely.
The F73 fault code on a Vaillant Ecotec boiler can be a frustrating issue to deal with. However, by following the steps outlined above, you should be able to diagnose and fix the issue. Remember, if you are unsure about anything, or if you are unable to fix the fault on your own, it is always best to call a professional. They will be able to diagnose and fix the fault quickly and safely, ensuring longer performance of the equipment. Without any doubts or confusion, you should do well to communicate and collaborate with the most successful service providers.
