People,
I recently purchased a Silvia after four years of "playing around" with a Sunbeam machine only to discover that my wife and I are running into some early teething problems with the unit. When the unit arrived I used the coffee from my cheapish grinder only to discover that I had a pool of black fluid in my cup.
We assumed the grind was too course and not up to the requirements of a "rea"l machine, to extract crema. I quickly obtained an amount of feshly ground beans from the Di Bella factory in Brisbane set at the commercial grind that they use on their Wegas. I put through a number of shots on the machine single and double, heavy tamp light tamp, over filled/ under filled etc and I could not squeeze out more than a tea spoon of crema. I estimate that I was getting about 40-55 mils of "fluid" in about 15 seconds, as we all know is weigh too much for that time span.
I have since ran through a number of other beans at even smaller grinds, starting at two settings from Turkish coffee!!! with again different tamps and amounts and I am still strugling to obtain a good amount of crema. The amount of coffee I am ending up with leads us to beleive that there is a problem with the water flow of the machine, as have used fine to very fine grinds with light and hard tamps and still seam to obtain the same amount of coffee with about say 10% variation.
I am at a loss to think what the problem is to be honest. I am no barista but my wife was and she thinks I should take the unit back and suggets it has a pressure problem of some sort and may need an adjustment of something??. I have also ensured that the machine is as "heated" as possible too assist in etxraction, but again still too much liquid being propelled into the cup.
This is my first message on this site and I know it is a doozy but does any one have any ideas or has heard of silvias having some issues? at times that may explain this. Is there a "standard" amount of water that should flow through the group head in a given amount of time to check pressure etc?.
Any how...awaiting any replies I can get
Thanks
