Tassimo machine - needs repair (Headington OX3)

Tassimo coffee machine with large tank - not working, but may be fixable if you know your way around these things. Water isn’t getting through to the nozzle, and instead leaks from the bottom. Milk disks work fine, which makes me think the problem might be about a broken hose rather than the mechanism - but I can’t see anything obviously wrong inside. Collection from Headington- drop me a line if you’re interested.
