The steam valve on my Semiautomatica has become inconsistent; it leaks a bit when I touch it to turn it on, and it does not always turn on when I rotate the knob.

Is there any point to removing the steam valve knob to see if there is something I can do to fix it? If so, does the knob simply pull straight up to remove?

These parts are expensive. I see that the knob is almost $10, and the valve itself is $65!

It just pulls up off a square shaft.

Thanks Dave. I did not want to break it trying to fix it.

they are pretty simple
is basically a cock valve
you can open it after removing it from the machine (note the lock nut)
pull the little handle stop pin out
then with a Allen wrench (maybe a 10 0r 12 mm don't recall off my head)
teflon seats and a stainless steel semi/half ball
you can try cleaning the interior and the pieces then see
