Below is a photo guide on cleaning and installing a new expansion valve seat. Before doing this you'll need to remove the top panel(check out our guide on panel removal here) of the machine, turn it off and close the inlet water line if direct plumbed.
Tools required:
- flat head screwdriver
- angled pick
- 1.5mm angled allen key
- adjustable wrench

saved me a lot of trouble. thanks a lot
Thanks for the post. How tight should this be set back to? Also, mine didn’t had a 1.5mm set screw. Should it?
I also wonder how tight it should be. After cleaning and assembling everything my water tank is emptied after just two shots (which was the original reason I checked the OPV, but before cleaning it took a little bit longer to empty it). I've tried to adjust the pressure as well but with some settings my duetto III begins to leak a lot instead.
