Wish all "how to" videos were as good as this one. Good audio, you speak very clearly, paced nicely, well lit and the pump was nicely highlighted. You gotta watch a lotta videos before you find one as good as yours. I'm off to figure out why pump #2 on my Saeco Exprelia is putzing out. Thanks again.

Thanks for the video Geoffrey, I just recently took the pump apart but I couldn't figure out where the retainer type looking ring was suppose to go. So I just left it out then put it all back together.........all this is a first time for me, just didn't want to throw away a machine that still looks New! Thanks to you I know now that strange looking Retainer Washer was actually a broken spring......it looked like a (C), thank you Geoffrey. I had started taking the whole machine apart, after seeing your video I came to a sudden stop..........Whew! ,I was a little worried about trying to get those Teflon Lines out without breaking them. Now I don't have to, it's a good thing I took all those photos and made labels where all that those parts do back together..........LOL Also I just wanted to mention I will save that pump as a spare since I just replaced it with a New one. Oh Geoffrey I don't know if you will ever see this comment or not but I had a Question for you or anybody, as I was putting the pump back together the two little knobs on the side broke off the housing where the two screws are all I could do was just put the two screws in and was wondering if you think it will work again or not.
Hi Allan, I'm glad the video was helpful for you! I'm unsure what knobs you are referring to. Does this mean you weren't able to properly fasten the outlet onto the rest of the pump?
@@gpereir4 The knobs I'm referring to.....after you remove the two screws from the housing, then you open the valve, the white plastic valve is held together by the two pimple type knobs one on each side of the white valve ......you have to turn the valve shaft then slide one part away from the other in order to open it up........I noticed on the table there was two little smaller than a bee-bee ......laying on the table so I was wondering what they were... then I noticed it is part of the lock mechanism on the valve as you turn them in opposite directions in order to open it up........putting all this aside Geoffrey do you know of any links , for the Saeco magic comfort Plus Redesign machine that sells any of the parts?
Thx dude. Your video made my pump work again. Even the feather wasn't broken in mine. It was just a matter of esambling and reasmbling the pump. Bang! THax again..
Thank you! I have a Cuisinart em100 and found another video that had instructions to fix the pump issue. Umfortunately, the whole thing came apart and I couldn't figure out the placement where the 2 springs and metal mechanism go. Glad I did a search for the pumps make and model#. You can also order a replacement pump for around $40. Happy to save $$ and keep my espresso maker out of a landfill!
Great runthrough of the guts of this pump. I was worried that I was going to have to dig in and take mine apart as well, but if your Silvia is not pumping water, try taking a large syringe and push water into the intake line (the longer one) while running the group head pump. One or two pushes should do it, then put the line back in the tank and see if it siphons water through the group head and the steam wand.
Yes, great point Robert. This sometimes happens on brand new machines out of the box. It is called hydrolock, and essentially air in the intake line prevents the pump from sucking water through the pump. Priming it with a syringe can solve this problem.
I enjoyed this video very much to the point I totally disassembled my delonghi icona due to a significant low water pressure. Checked all the components and seems fine. No change in water pressure. Or is the time to change the ulka pump? Appreciate any reply. Thanks in advance
Hey, thanks for the comment, I am glad you enjoyed the video. It is possible that the pump is to blame. I would maybe unhook the high pressure side of the pump and "bench test" it to see if it seems like it is pumping water properly. Is there an over-pressure valve in the plumbing of the Icona? I find often these valves lose their ability to hold pressure and need to be adjusted back in.
Thanks for this video. My ms Silvia has the same symptoms you described. Change in tone/much more quiet sound from the pump and no output. I took it apart hoping to have a similar break and found nothing wrong inside the pump. Reassembled the machine and made espresso without issue for another year. Now just this week the issue has returned but the pump usually functions correctly after flipping the switch a few times. Now I've discontinued use as I eventually ran emptied the boiler and could not safely keep the machine on. Going to take it apart this weekend to see what I can find...
@Westley Thayer Let me know what you find! I hope you can fix her up easily. I kind of had a similar span of intermittent functioning, but it was because the small piece of broken spring kept jamming up the piston, then working free, and then stopped it altogether. If you want to keep testing the pump without fearing for your boiler element, you can simply unplug one of the leads to the heating element right at the top. that will allow you to test the pump without the element burning out. I'm interested to hear what you find, let me know how it goes!
Thanks. If again I find nothing is broken I'll try cleaning the pump components... I wonder of the springs just wear out over time and stop "springing"
@@WestleyThayer Could be, or it could be worn out o-ring seals too not keeping pressure in the pumping mechanism. Could just be the electrical coil wearing out too, who knows! Give it a good clean and inspection, and report back. Have a great weekend!
Yes it is pumping water, but it might not be able to make rated pressure of 10 bars, used on most espresso machines. Can you check to see if it is making rated pressure? If not then take the pump apart again and see if you can find a spring locally of the correct length and wire diameter.
Hi there, these Ulka Pumps are rated to put out around 15bar. A decrease in pressure would be a good thing in my opinion, as they run way to high from the factory. My Silvia is pressure tuned to 8.5bar dynamic pressure via the OPV. After putting this pump back in there was no change in the way the machine behaved, so I'm assuming the pump didn't lose too much pressure.
not for the price for the reduced performance and likelihood that it will break again very soon....i actually wanna buy a pump just in case the one that's inside will fail because the machine was used heavy and built in 2009.....i got it 1 months ago and first time i started it the pressostat broke....so i guess the other thing that will break soon are pump and threeway valve....
@@gpereir4 yep got her working,I disassembled pump, soaked everything in vinegar for 10 mins, put everything back together bang that did the trick.. vid was a big help thanks!!!
If one decides to replace the broken spring be careful, the new spring should be stainless steel or else it will rust quickly and get pretty nasty in there. I ended up just replacing the pump in my Silvia V4 from 2014. Used the EX5 pump, about $25 USD.
Yeah these pumps are tougher than they seem. Very simple in construction. If the loose pressure it’s either the ball or o-ring in the pressure side to blame, so simple
@@adilsokolovic12 It runs on AC power, so I don't believe so. I could be wrong. I always mark which wires go where with a sharpie before disconnecting. I don't think it would hurt anything if they were connected backwards, you may as well try and see if the pump runs. Good luck!
Where I am, the pump is about 40$. It’s not a huge expense, but at the time of making the video, I was a student, and money was tight. I also like taking things apart and fixing things, and I was able to get the machine up and running again for zero dollars. I was very glad at the time not to have to buy a whole new pump. I made the video as I was working on the pump in hopes that it might help someone who wanted to fix theirs, or just provide others with a look inside the mechanism. Thanks, take care also!
Don't think there was any stress at all. Rather, someone being resourceful and not sending things to the landfill which can easily be repaired. Please point me in the direction where I can order one for 16€. The average rate I've found including shipping is around $50. There's plenty of other things I'd rather spend $50 bucks on besides an easily fixable ulka pump. But we do agree it's a good video none the less.
@@greatmaddyave It goes on the narrow end of the small conical spring within the high pressure outlet. If you search Ulka Vibratory Pump diagram, you should see a nice schematic that shows it all going together. Good luck!
Do you mean the actual electrical coil that controls the vibration pump, or the coil spring? If you mean the electrical coil, the unit is essentially not repairable.
Ric Vieira Yes, so the EX5 has a brass high pressure outlet instead of a plastic one. This means it is rated to pump hot water, the EP5 is only rated for cold. That’s the only real difference as far as I know. The internals should all be the same. Hope this helps!
"That piece of sh...rapnel" 😄 Why for god sake is there no replacement kit just of that whole plastic tube unit... No you have to buy/waste the full pump with the coil and all that copper inside that never ever wears off. Its a shame.. It is even easier to just replace this in a machine instead of the whole pump. (nowadays I just extract that plastic unit from a new pump and replace it in a machine leaving the rest untouched)
@@gpereir4 great effort to temporary fix your machine while you wait for a spare part. I'm telling you the pump is struggling to make 9 bars now, that's why the 'rpms' are so high. "Pumps have an average life of between 15-30,000 cups (4- 8 years) and loose their ability to extract at 9 bars of pressure over time."

Yes very tough indeed. I used to keep a few spares on hand for my Silvia, but the pump never died!
Did it end up working.. it should also have a small ball inside, which is made of plastic but it ends up disintegrating
It ended up working fine for years. The ball was in fine condition. The pump was relatively new.
Good job 👍
Thanks!
Better turn the spring around so the sharp part presses into the metal rather than the plastic
When you connect the different pump is there a + and - you have to connect correctly?
+ and - for the wires
