Subject: Handpresso Lubrication/Repair
 

My two Handpresso units and have both developed leaks which I've fixed by lubricating the units.

Here's a link to the secret lubrication instructions: Click Here (www.ultimateespresso.com)

Here is how I did it:

Written Description

1) Remove by gently pulling, without twisting, the valve cap on the reservoir side of the unit.
2) Using suitable tool (e.g., snap-ring pliers), unscrew and remove valve chamber cover that has two small holes on the reservoir side of the unit.
3) Gently pull, while twisting in a single direction, valve to remove the valve the portafilter side of the unit.
4) Lubricate the metal portion of the valve with vegetable oil.
5) Lubricate both sides of the valve chamber in the body of the handpresso.
6) Replace the valve by reinserting it into the Handpresso from the portafilter side of the unit.  Gently turn the valve while reinserting it.  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.

Enjoy!

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.

many thanks!
