This saeco classico has been sitting unused for a couple years.  I tried to prime it but no water flowed.  I took off the the top plate and tried to force water into the pump with the pump running and the water would not go in the pump.  The pump is humming when switched on.  Is the pump shot?  Is there a way to descale the pump if I cannot get solution to go in?  I can still get a little steam, but nothing flows through the brewhead.

Open the steam wand wide and run the pump.  That eliminates the group from the equation. I can't tell from the description whether the pump is not working or if the group is plugged and will not allow water or air in.

I opened the steam wand and ran the pump.  The pump sounds like it is running but no water flow.  I tried to force water into the pump using a baster inserted into the pump feeder tube.  Then I removed the baster bulb and blew with my mouth, still no results.  It seems to be completely plugged somewhere.  IM ready to start disassembling, any suggestions?

Since you asked, this is close

Before total disassembly, you could try removing tubing and make sure all tubes are flowing just to isolate the problem to intra-pump and not tubing in or out.

The website was great info...gave me some confidence for a pump teardown.  After a descaler bath and a few adjustments I was able to get water flow for the steamer but not enough pressure to make espresso.  I guess I will have to be happy with chai chocolate lattes until I can gather the funds for a new pump.  Thanks for your help.

After some online searches, I read that if there is good flow through the wand then my problem is not the pump.  I was reluctant to tear down the boiler because of all the wiring and connections but it was a slow night and I had a fix it or trash it attitude.  I used the ulkapumprepair.blogspot.com as a guide.  After poking around with a wire in the disassembled boiler I found that the valve spring at the base of the boiler tube was frozen shut.  I couldnt remove the retainer and i didnt want to break it so I just soaked the bottom boiler piece in diluted vinegar (this probably is not recommended).  After about 30 minutes the valve came loose.   I had some reassembly problems which required backtracking, including a leaking steam wand connector at the boiler, fixed by doubling up the o-ring.
I have a new appreciation for the inner workings and a better understanding of the importance of regular descaling.  Anyhow all is well now, I got my machine working again and all it cost me was about 8 hours of reading and labor (and backtracking) and a couple o-rings.  Makes me want to look around for some expensive castoff machines which the owners are afraid to take apart.

Yep, that the valve is the usual culprit. You learn a lot about your machine. Now you can post and help others.
