Well, i removed the o ring and verified that it is in good condition. I greased it and the ball (as per the vid) and put the wand back - i donāt find it necessary to turn the machine upside down!
I will test when itās hot tomorrow morning, but, right now (cool), it still creaks. The only thing i havenāt tried is to file the top of the spring. This is looking like one of those things Iāll just have to live with lol.
