Can you guys please have a look at the video and let me know what may be going on? The pressure bounces with a puck of espresso in the portafilter, but seems to work ok with a blank portafilter (no holes).

If your pump is getting quiet as the pressure falls, then kicking back in then restalling (Sorry, no speakers on this computer) then the pump is unable to maintain flow at more than 11 bars pressure. The pump is getting weak and will get worse in time. You could adjust your relief valve down to 10 or 10.5 Bar, continue using it and if it's making decent espresso enjoy it for several more months. Buy a new pump and plan to change it soon... If even with a relief set to 10.2 Bar it fails to provide a steady flow you have to replace it now... NOW!!! Or you will have yucky espresso tomorrow morning. Eww.
