small black circle...
Hey Gansky
That black circle is a 'testing port' for the full flume. The idea was that you could 'test' the water being filled into the outer tub and adjust it accordingly, if you so desired. God knows why!
Mike: Yes, i suppose that's true re: the design of the control panel.
Oh...and by the way Mike....i'm having a machine shipped over from New Zealand that you and other UK members will have a particular interest in!!! Don't ask me WHEN it's arriving, i only paid for the shipping 2 weeks ago.
Cheers
