I've just bought a Bosch Tassimo Suny coffee machine (TAS 3202GB) and it only fills the cup up to about 1/3. The instructions (all pictures) seem to indicate that I need to press the button again, either 3 times or for 3 seconds to get a full cup but it's not doing a thing when I do that. Any ideas please? Anyone else had the same problem? Is it me or is it faulty? Thank you :)
