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

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.

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

Thank you Milen! I enjoyed learning about these pumps!
Thank you, Milen. This is one of the most helpful espresso-machine-related clips on CZcams. Very clear presentation, lots of useful information.

Thanks for making this video, after disassembling and reassembling the water pump, I got an old carpet cleaner going again :)
Thanks, Milen! Your video really helped me out to identify a defective pump.
