Troubleshooting the Dreaded F75 Fault on Your Vaillant Boiler

If you’re facing the F75 fault on your Vaillant boiler, the first step is to check the water pressure. A common cause of the F75 fault is low water pressure, which can be easily fixed by repressurizing the system. Simply locate the filling loop on your boiler and slowly open the valves to allow water to enter the system. Keep an eye on the pressure gauge and stop when it reaches the recommended levels.

Another common culprit of the F75 fault is a blocked condensate pipe. This pipe is responsible for removing waste water from the boiler, and if it becomes blocked, it can trigger the F75 fault. To fix this issue, locate the condensate pipe and check for any blockages. You can try clearing the blockage with a pipe cleaner or warm water. Once the blockage is removed, reset your boiler and see if the fault has been resolved.
