Turn the unit over and lubricate and replace the oring (that has just fallen out) on the metal portion of the valve. 7) Replace the valve chamber cover using a suitable tool, being careful not to overtighten. 8) Cycle the valve 15 times. 9) Seat the pump handle against the body of the handpresso and turn counter clockwise, unscrewing the pump from the body. 10) Remove the pump from the body, and extend the pump handle and lubridate the pump o-ring with vegetable oil dropped inside the aluminum tube. Reinstall the pump in the body of the Handpresso.

Hi I was quite happy my Handpresso for about 2 or so years .... till stopped pumping. Before getting into coma (I still hope is not dead yet) the pump got stuck and then got loosen moving up and down w/o any force applied, as if some valve or inner o-ring failed. Saw your post but could not enter your picasa link , I'd much appreciate if you could help.
