I have a BES820 and it leaks a bit into the tool tray.

I really like this machine and want to repair it; But first I need to diagnose the issue.

I suspect that it could be an issue with the solenoid.

Does anyone have any other ideas on what it could be?

Also, I have a non operating Breville 800ES - I am not sure if the parts in this are operational. If anyone could shed some light on this, that'd be great.
