Hi
Your brew head gasket is leaking and needs to be replaced. remove everything and turn the machine on its top. Look ate the brew head inside there is a black gasket and it should be clean and flat. If its cut or curled it needs to be replaced. Not cleaning the brew head will cause this gasket to be cut and after a while it will curl and not seal.

Hi,

Make sure you have brewing unit in start positions, if you have a press on your brewing unit make sure to press it to you hear a tick, then you can fit it in the machine.
