It has served me fine but it is like 10 years old. It has broken three times and twice I have been able to fix it myself (fittings). It is like $130 to just have it looked at and no guarantee it can be fixed (for less than the cost of a new machine). Given the age I am reluctant.
When it is turned on the motor engages to move the grinder for a few seconds and then just moves it back (to the bottom position). An electrical type override as I took it apart and there is no mechanical obstruction. When I had to send it in before for the exact same symptom they told me yes that is a start up check that failed. Same symptoms does not mean same failure but I was not charged for parts before.
Only place I can find a service manual is a Russian domain. I do computing for a living and the link to it is a script. I know not to click it.
Any advice on how to fix this or how to get a service manual?
