A seven year old video that's informative, detailed and still relevant. Nicely done, sir!

I love how your english is not perfect, but yet you manage to explain this SO much better than any engineer ive met, thank you for this

I wish there would be more people explaining things like you. Thanks for taking the time!

Thank you my dear! I’m from Saudi Arabia and I had a problem with the water pump and changed the O ring. Therefore, everything is fine now! Thank you again!

Many thanks for your pump repair video's. My Miele CVA 620 has not been used for a few years and displayed the usual 'expel air' and a very noisy pump. Managed to extract the pump (quite difficult!) stripped down according to the video and I'm now enjoying my first cup of coffee for a long time. Great of you to share your knolwedge Milen.

Thank you! You saved me the replacement cost of a pump. Back flow valve (mushroom valve) was stuck. Awesome Dude!

Thank you, Milen. I just fixed my Gaggia Classic which uses the same motor. The little ball got stuck and the motor went super quiet. Indeed, so easy to fix. 👍

What a great video. Thanks for taking your time explaining how it works, I just fixed my Philips Saeco Intelia machine thanks to you!! Nothing was broken, just the small rubber valve was stuck. :)

Thank you for the great explanation - I was able to bring my Saeco Intelia back to life! Wishing you all the best!

Thanks! The water pump on my carpet cleaner wasn't working. Although the internal mechanism was slightly different from what you show, the information you presented was spot on. The back flow preventer was stuck & easily fixable. You saved me $60!

Watched your video, spent £3 on replacement ball and washer for the pump, coffee machine fixed!! Thank you very much for the clear and easy to follow help!!

Thank you so much, my milk steamer has a small 16W pump (Quickmill evolution 70 machine), and steam stopped coming out. I took the pump apart and put it back together, and now I have steam! You saved me a lot of hassle as this part was out of stock everywhere...

I almost threw my espresso machine out! Tore it apart wondering how to check the pump out! Thank you so much for this video which was very helpful.

Waoou, thanks so much for your Video. The local repair shop couldn't even find where the problem was coming from. You are a star to take the time to post such detailed video. Well done

Your repair demonstration is excellent and a money saver. Various versions of the Ulka pumps are used in medical equipment, to pump water or chemicals. After viewing your video, we have repaired several pumps, which we would have normally thrown out. We found problems with the “stuck ball” and replaced the smaller o-ring. Now the once malfunctioning pumps are all working properly. Thank you.

Thanks a lot! You just saved me about $50 for a new pump. Successfully repaired pump on my espresso machine.

My Delonghi Magnifica is working again simply after taking the pump apart and putting it back together. You gave me the confidence to do it. I don't know exactly what the problem was, but it got it going. Thanks!

Thank you, Milen. This is one of the most helpful espresso-machine-related clips on KZfaq. Very clear presentation, lots of useful information.

Very nice video. Thank you. I disassembled and put back together my pump and now is working perfectly :)

Excellent video! Thank you for making it. I just purchased an espresso machine that had been in storage for years. The pump would not prime. I used a plastic syringe full of water, to force water through those check valves, by removing the filter from the water supply hose, and putting the syringe onto the hose. (I got the plastic syringe from a local drug store by asking them if they had syringes for giving pets medicine. This kind of syringe has no needle.) After the pump was force primed, it worked, but the flow was very low. I removed the pump, and took it apart as you show here. I found that small 9mm x 5mm x 2mm o-ring was hard as a rock. I replaced it with one from the plumbing department in the local hardware store, and now the pump delivers a lot of water! Saved myself $45.

Excellent! I have a 2005 Starbucks Barista which quit pumping after sitting for several months. I had tried other ways to try to get the pump to flow but none worked. Thanks for showing how to disassemble the pump. Once I did that and reassembled it worked. Thanks again

Thanks, Milen! Your video really helped me out to identify a defective pump.

Thanks, brilliant video, lots of useful information repaired my machine for free thank again

Thanks to your video showing the inside, I repaired the pump in my Nivona Romatica coffee machine. I had put a dodgy water filter in the machine. Water flow washed out the filter's insides and through the pipes, the water flow controller to the pump itself. Thank you for sharing this.

Thank you very much for taking the time to make this video! I only wish I had seen it earlier as have I already ordered a new motor. Will try to repair the old one anyway and have a spare! hehe

Thanks for making this video, after disassembling and reassembling the water pump, I got an old carpet cleaner going again :)

Great video, with just one note. I had a loud, non working pump in a Starbucks barista that had been sitting for a while. What I did was to elevate the water reservoir above the machine, forcing water into the pump. This allowed the pump to push with water instead of air, freeing the black rubber valve. It worked, and I did not have to take out the pump.

Thank you for your video which is well explained. As soon as I have repaired my coffee machine , I will drink a coffee to your health.

Thank you!! Yes, between the total dismount of my De Longhi EC680R and the whole job itself (2 hours), I now have a working coffee machine which was going straight to the bin! All about a stupid spring and a 2mm ball stuck, who would ever figure it out!! Thank you 🙌💪👏👍

Thank you for this very informative video. After watching it, I managed to resuscitate my 20 year old Ulka pump.

Your explanation was perfect!! So clear and useful. Thank you so much from Argentina

Amazing! Thank you. I watched it all despite my pump being the disposable type shown at the beginning. Very generous ❤

Super efective video, took mine' apart, and sure enough, the "mashrrom" valve was stuck. It works great now!!! Thanks a MILLION Buddy!!!

Thank you Milen! I enjoyed learning about these pumps!

Thank you very much, you just saved my old DolceGusto coffee machine, the little mushroom ball was stuck in my case after a long period of not using the machine at all. Thanks again very very much

Thank you for the video. I'm enjoying a nice espresso because of your informative video!!!

thank you very much for your great explanation. I found two little black plastic pieces near both little balls. Removing them solved the problem.

You're a true hero- 👍 you're video is easy to follow and well- explained.

Thank you mate! you saved my ULKA pump from a Lavazza EP951 ! back flow valve stuck! i noticed that my pump hasn't the little ball, maybe a different model!

Thanks a lot man! One suggestion is that to write the common coffee machine types that uses the same pumps. I had to open it then figure out where is the pump and finally get the model

Thanks. You just saved me £200 buying a new Dualit coffee machine. The machine was making a loud noise and no water was coming through. Such a silly little spring stopping the whole machine working. A 5p spring stopping a £200 machine...

Hello Milen, i think many repair shop don't like you explain all this. Tank you, i have repair my selonoid valve with your video...

absolutely great video I've ever watch better than any other teacher or book

Thanks! You just saved me a HUGE repair bill from the supplier !

Thank you for this very informative video. I repaired my pump for £2.07 as opposed to having to purchase a complete pump. My Magnifica is now working quietly and properly. I am both delighted and relieved with the result. 👍😊

Thanks a lot for this, complete, instructive and clever thought 😌👌 and you have the same voice as me, without the french accent😂😂.. that was really funny to hear 😂🔥👌

Thank you so much. The valve was stuck in my case. If it wasn't for your video, I'd consider replacing the pump.

Great video, working on my breville barista with using this. Keep up the great work!

Thank you so much for this video! With your help I could fix my water pump, and thus also fix my Espresso machine :) You are awesome!

I disassembled my whole coffee machine overtime. Now there is still no water. The next step is, to check the water pump. Thank you very much for the explanation. 😁👍

I appreciate your time. I repair autoclave and my cofee machine use same pump but I never care that the plastic ball shrink in size by time, thank you again.

Very useful video, helped me fix my DeLonghi. Appreciated!

Perfect. You answered all my questions at the very beginning. I have to throw away and buy new one :))Very informative and helpful, Thank you.

Very well done. Not easy for the english but you`ve been so friendly and helpful. Now i`ll try to check and repair in the case the water pump from De Longhi ec200 cdb. The coffee machine is been stopped for more than 2 years, so the water now isn`t going out. I think, probably are the orings or tha same that you show up. Thanks again, all the best*****

Very useful, I repair my pump! Thanks a lot!

Thanks so much for sharing! Great to learn about the ULKA water pump. Very informative!

you are the man ! your all videos are very hulpfully for me,, greetings from Turkey

Really useful and detailed! Big thanx from Greece!

Perfect video. Helped me fix (vs replace) my Ulka EAP5 pump which had a jammed mushroom rubber valve.

Thank you for the very useful video. You helped me to repair my pump!

It was very helpful,I fixed my ULKA pump.Thank you so much!

Extremely informative video.Thank you very much for your time!

Thank you sooooo much! I fixed my espresso machine using your video!

You are a genius. Thanks a lot. This really helped!!!!

So very informative, thank you Sir! You are awesome!

Excellent video. After my 15-month-old Miele DGC 6765 steam oven gave an F10 error, Reddit or Houzz sent me to this video. Inside the Miele's very similar vibratory pump, model ARS MPP2.02.041.3/ST/S 208-240V, I found a broken .25"x.75" spring which I was able to replace with a stainless steel spring from amazon in a 400pc variety pack for $16. Problem solved thank you. Much better and quicker than the extortionate price Miele would charge to repair my just-out-of-warranty and very-expensive-to-begin-with oven. Now I'll be ready if and when it happens again.

Thank you! Very helpful vid, helped me a lot in deteminating the issue (low pressure) with my Isomac Giada. Pump in the machine was about 12 years old..

I wish all video's were off the same quality. Very educational. Congratulations man . I subscribed to your channel

Great video!!! thanks for your pump class!

Thank you man, i fixed my carpet washer machine's by that video.

Thank you for your explanation! Very nice video!

Thanks, one less water pump in the dumpster. I was just going to buy a new one as I did not think that could be repaired.

Thanks Milen you saved my weekend.

fixed in my case it was the mushroom was stuck, thanks mate fabulous

Thank you very much for your detailed explanation. Now my pump is working again :-)

Thanks for posting this; I'm going to try to fix my coffee machine now instead of throwing it in the garbage.

Thank You, very informative and helpful

Thank you! I am also enjoying a nice espresso thanks to you. You are awesome!!!

Your video helped me to unblock my pump, thanks!

Thank you for this helpful Video !

Super Super Helpful and Useful. Thanks a lot man!

Thank you so much. This helped me find a stuck rubber valve.

Thank you for explaining this. My dolce gusto is working perfectly because off this video. Thank you so much 😁

Excellent video, very helpful. Thanks a bunch!

Perfect and clear explanation I'm suspecting that my pump is the issue and from the search I'm sure it is a minor issue. BTW for the boiler when could I say that my boiler needs replacement? Is it when there is a visible leak?

Thanks! Got my Kärcher textile washer back working because of this vid!

HI! Many Thanks! Very helpful video!

Thank you! Good, helpful video.

Great video, it explained everything I wanted to know. Many thanks

Hi Milen. I have the Type EP5. Do you know the exact measurements for the little rubber O ring that you mention that makes it lose pressure? Thanks

Super, Merci. J'ai finalement trouvé qqn qui parlait encore plus mal anglais que moi ! 😉

Excellent video and very well explained

Thank you 'brat'. Great video. Pozdrav do vas.

Fantastic video very helpful cleaned mine pou and works great again thank you

Thank you! Wonderful information!!!

Thank you, Milen, for all the good information, question what do you do when the little plastic balls are the problem? do you replace them with other parts you have hanging around or just buy a new pump or maybe use stainless steel ball bearings?

Great job. It saves lots of money. Thanks.

This was very helpful for me - Thanks a lot!

Nice video/explanation. Well done.

Благодаря Стефане, утре ще диагностицирам помпата!
