Vaillant boiler leaking

Hello,
My boiler leaks from underneath the boiler once I put on shower/hot tap or heating. Then it will lose pressure completly. What could this be?

Could be coming from anywhere. Open up and look

Depending on which Vaillant you have, could be a failed condensate hose, which could be dangerous. I wouldn’t advise opening up the boiler, best just getting a gas safe registered engineer.
