Posted Tue Jun 25, 2013, 11:11pm Subject: What's wrong with this Saeco Aroma?
I have a Saeco Aroma that has been serving me well for over five years. Recently, its pressurised filter holder has become clogged when using my habitual grind. While I am able to squeeze out a dose, it does not have the body of an espresso. I ran descaler through the machine, but this has not improved matters. The motor for the pump becomes quite strained. What is the problem?
(a) is the motor providing pump pressure not working as it should and needs adjestment or repair? (b) does the pressurised filter holder need replacement? Is it possible to get a replacement?
I have uploaded a video so you may see for yourselves, although the machine normally is less effective than shown in this clip

It does appear that the pump is nearly stalling, from that clip. Though, as you say, it's not that bad in that video. It could just be that your espresso grind is too fine for the machine. A new pump could overcome that problem, at least for a while, though getting slightly coarser espresso to match the machine might be a solution. I don't think that the pressurized portafilter is internally clogged since the flow is fine without the Illy in it. You could try to depressurize your portafilter. That Illy is plenty fine and should make somewhat drinkable espresso without the hocus pocus of end-line pressure to create crema. I don't know what that machine is worth to you, but you might consider upgrading rather than investing too much into repairs on that. Something with a relief valve, a three-way valve and a non-pressurized portafilter will burn out fewer pumps.

If the portafilter mechanism is gummed up with coffee oils it will not open with just the water in most cases and the pump will quite down/struggle as well, since that (the portafilter) and the coffee are the only 2 things conuterpressuring the pump out put (we are not considering scale inside the passagesfor the above reason) it's ether your coffee grind too fine (as mention above) or just time to replace the pump normally a machine like your after a pump replacement/repair testing should still push water through the portafilter with coffee very fine and TAMPED (and when you remove slowly the portafilter you will have a mini explosion
