Welcome to Coffee Snobs jaaazd.
Someone will surely come along soon that knows about your particular machine.
In the meantime I recommend leaving it off.
You dont want to do something that could cause it to burn out the elements.
As for the cleaning agent some more details would be appreciated.
Is it a powder?
Is there a brand name etc?
The more you can tell us the better answers youll get.
Lucky you by the way.
Do they have any more free machines? ;)
