Welcome to CoffeeSnobs....... [smiley=thumbsup.gif]
If possible, try to find a copy of a service manual for the Bo-Ema as maybe a PDF download from the Bo-Ema website. Failing that, contact their head office and see if you can talk to someone who will let you buy one..... You might be lucky.
As for the rest, well I suggest you read through all of the resto posts in this category to give you an idea of what to check, etc and Im sure other Bo-Ema owners will come in with specific advice for you. Bo-Ema machines may not look as flashy and covered in all the bling of several other machines but they are well built, work well and are fully supported here in Australia (since theyre manufactured here ;)). All the best with your new acquisition and wish you many glorious espresso shots and a Happy New Year for 2008 8-) ;D,
