VAILLANT BOILER F75 FAULT CODE

The fault code is caused by different reasons but usually, it is about the central heating system of the boiler. When the boiler does not detect any pressure and is not able to circulate the water that is in the central heating system around the pipes. You do not need to change the boiler if you have this error because you can see this problem even on the best boiler. There are two different reasons that the central heating system of the boiler is giving the fault code F75. It can be about the clogged water pressure sensor and the faulty pump defective or there is not enough water in the appliance that you can check. There are some steps that you need to follow to detect the F75 Fault Code on the boiler.

How to Detect F75 Fault Code

Press the reset button on the boiler to reset the boiler. 

You need to wait a few minutes.

You should run the hot water and the boiler can start to work again.

After you run the hot water, the heating pump should be starting again and circulate the water to the tap.

If these steps did not change anything on the boiler system, it means there is the pump defect and you need to contact the service instantly and ask for the new pump for the boiler system. It is better to contact the service instead of buying a new boiler.

If the boiler starts to work after you restart the boiler and run the hot water but stops working after a few seconds and you receive the Fault Code F75 again, the problem must be about the pressure sensor. It means the pressure sensor is not working any longer.
