I inherited a Krups Type 964 espresso machine from my parents. Actually, I found it under a pile of junk in their garage 5 to 6 years ago. It had been under that pile of junk for probably more than 10 years. I cleaned it off and ran white vinegar through it a few times and it has worked mostly fine ever since. It can't push water through coffee that is too finely ground and it has a leaking overflow spigot (which I fixed with some flexible tubing). I've never used the milk frother.
Besides that it has consistently made 1 to 2 double shots of espresso for me everyday for the last 5 to 6 years.
What I am wondering is - at point should I just get a new espresso machine? Is there a chance this old one will violently rupture/explode due to use and age? Am I better off just investing in a new one?
