Vaillant F75 Fault Code
Is this a Common Issue with Vaillant Combi Boilers?
Does your boiler have the Vaillant F75 fault Code?
At Some point in the future if you have an older vaillant combi boiler you will come across the Vaillant F75 fault code at some point during its lifespan.
While these boilers are known for their efficiency and reliability, like every piece of machinery with moving parts they can breakdown whilst working in your home.
So lets take a look into what the F75 fault entails, its potential causes,
The F75 fault code is specific to Vaillant combi or system boilers that work on sealed systems.
It indicates a problem with the pressure inside the Boiler. Specifically.
What factors can lead to the Vaillant F75 Fault Code
Identifying the root cause is crucial for successful troubleshooting and getting your back up and running again.
One common reason is a leak in the Central Heating System, which can cause a gradual drop in water pressure over a period of time.
Check your central heating system including valves, radiators and pipework for any visible leaks. Additionally, the expansion vessel, responsible for maintaining a stable water pressure, might be faulty, leading to pressure fluctuations and triggering the F75 fault.
The most Common cause is a faulty pressure sensor itself. With constant use the sensor can wear out or become clogged with Sludge, causing inaccurate readings and the F75 fault is triggered. Once this fault happens it is essential that the sensor is replaced. We have tried in the past to clean these but it has never worked.
Another cause is a faulty pump that has either shortcircuited or seized up. This also causes the Vaillant boiler F75 fault code as the sensor is looking for a spike in pressure caused by the pump activating. If the sensor cannot detect this pressure it will go to the F75 fault.
If you have this fault then the chances are that you dont have a good quality magnetic fillter Magnetic Filter. A magnetic filter catches magnetic and Detritus in the system this will help to stop the clogging up and help keep your pump in good condition.
