Glad the manuals helped. You can pul the plastic cover off the pressure gauge and then pull of the needle - very gentle and straight off, then pop it back on in the 0 position with the machine off. Thi is covered in more detail, with some other info you may find helpful here:
Can you revitalize a manometer?
and here:
Elektra Microcasa pressurestat problem?
The second thread will give you some good ideas about what you need to do to get your Elektra working at its best.
Cheers
Mike
