My Pinter 2 leaks when I fill it when brewing on ‘OFF’, why is this?

For brewing and conditioning, you should set the Dial to ‘OFF’. However, for filling and shaking, please turn to 1. Then turn the carbonation dial to ‘OFF’ and continue at ‘OFF’ for the rest of the steps, including conditioning. This is to ensure that the Fresh Press does not come out of the valve when filling and shaking.
