Soda Machine (A Bit Faulty) (HD4 Huddersfield)

Soda Stream Machine. Only a few months old but 50% of the time the water gurgles up and spills over. I've had the same problem with both of my Soda Stream machines (of this model) so it could just be me? Anyways, am upgrading so this one is going free. Collection from HD4 6QE.
