Troubleshooting the F75 Fault on Your Vaillant Boiler

If your Vaillant boiler is showing the F75 fault code, it means there is a problem with the water pressure in the system. The first thing you should do is check the pressure gauge on your boiler. If it is below 1 bar, you will need to repressurize the system. To do this, 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 around 1.5 bar. Once the pressure is correct, reset your boiler and see if the F75 fault has cleared.

If repressurizing the system doesn’t solve the F75 fault on your Vaillant boiler, the next step is to check for any blockages in the system. Start by checking the condensate pipe for any obstructions or kinks. If the pipe is clear, you may need to clean the condensate trap and check for any debris that could be causing the issue. Once you’ve cleared any blockages, reset your boiler and see if the F75 fault has been resolved. If the issue persists, it may be time to call a professional for further assistance.
