Topic: Another SL-90 adventure. (3 msgs / 60 lines)
1) From: James Gundlach
Monday morning I got up at 4:30, made my coffee and at 5:30 when the 
calls for two more coffees in bed came In, the Solis SL-90 quit heating 
the boiler after I had made the first one.    Since I had set up to 
make coffee in the thermos with the Militta filter cone, I went ahead 
used it for the other morning coffees instead of taking it to work.  I 
assumed it was the heating element so I e-mailed Josie Hein at Baratza 
to ask about the price.  She wrote back saying the SL-90 almost never 
has a heating element go bad and asked if it was not heating.  She 
suggested that a "cold solder connection" on the control board was a 
more likely problem.  I wrote back saying that the symptoms matched the 
"cold solder" description and she asked me if I could solder.  I said 
yes, she sent directions to identify the probable problem.  I opened up 
the SL-90, pulled the board, checked it out and there it was, a "cold 
solder"  Pulled out the soldering iron and some fine silver solder and 
fixed the connection.  Put it back together and fired it up.  Worked 
just like new.  Another case of great service from Baratza.  But, 
apparently another problem to watch for in the Solis.

Jim, you're making me nervous.  While I might be able to follow your 
directions to replace the gasket, there is no way I am going to solder.  I 
used to, when I could see, but learned that a blind man with a soldering 
iron is a free ticket to very badly burnt fingertips. [ouch]
I'm beginning to wonder if a very simple machine like the Giotto would 
serve the long term needs better.

Dan,
      I think you could do it if it is needed.  I think you could 
identify the cold solder connection by feel.  The bad connection would 
have the tip of the wire exposed so you could feel it while the good 
connections feel rounded with the solder.  I also think you could use 
the electrical soldering paste and a match to make the connection.  I 
did not use it for this one but I have used it in places that are hard 
to reach with electrical cords  in the past and it works quite well.
