Hi Ira Thank you to Ben, Barry and you for taking the time to reply to my post. First I removed the dispersion block and it was clean, good info on removing it and inspecting it. (I had a large blade stubby screwdriver that worked perfectly) Next I removed the upper valve body and found a small amount of scale.. After replacing the valve body I had the problem of a leak thru the filter head after moving the lever to the neutral position (center position) . A few actuations of the valve stopped this problem, I suspect a bit of loosened scale got under the valve seat. Also the problem with pressure on the PF seems to have disappeared as well. None the less I plan to order citric acid and follow Barry's directions for descaling the machine. The only issue I have in regard to descaling is that I have plumbed in my machine. I think I can overcome this by disconnecting from my water source and reconnecting to a jetflow pump I was previously using. Once again, thanks for the help
