Thank you, best regards!

Be careful with replacement springs, you actually need a spring that is designed for this device, not a random spring that happens to fit. The strength of the spring is the thing that pushes the water and what the electromotor (coil) works against. Using the wrong spring will damage things.

Hello, first try to descale the machine properly. The Teflon hoses may be clogged. If it doesn't help, please contact me again.

The blue part is a fuse in case the water pump overheats. I use hot glue gun to fix it. But the water pump can also be taken apart without removing it.

@@yt.myworks Thank you! I succeeded in replacing the small o-ring and ball by using the Amazon kit. Most difficult part for me was reconnecting the tubing at 6.07 min. Initially, I did not push it far enough into the holder, so the connector did not fit properly. Further, there was a lot of noise during the first run, probably because the pump/tubings/noise reducer had to refill with water again. But until now, after five cups of coffee, all seems to work properly again. Will test for at least a week before being satisfied ;)

Which problem do you have?

My mistake, so even the pump was changed correctly but I had some small stones stuck there in the pipes, I had to buy a special product and it worked fine. Thank you for your help

You have to pay attention to the degree of grinding, it must not be set too fine. Also check the brew group for blockages, then you can try to descale the coffee spout by repeatedly pressing the flush button.

I don't grease the "O rings" in the pump. I wish you much success with the replacement!

No grease. But don't forget to put rubber gloves on...

Also - do you know the difference between the white pumps vs red pumps?

Hi, the pump makes a loud noise when it has run dry and is not getting any water. White and red water pump have different parameters.

@@yt.myworks hi, so if the pump making loud noise and I am sure that even after replacing O-ring in it doesnt pump water because i tried everything. Its necesary to replace whole pump? Thank you for your help.

@@yt.myworks so, i just found out that pump is fine. So my problem is more further inside the machine. How can i unclogged rest of the machine if i am not able to pump water for descaling?

@HowAdd Keep trying to press the rins button with the descaler in the water. Leave the machine on for two to three hours. If that doesn't help, turn off the machine and leave the descaler on for the night. If that doesn't help, you'll need to disassemble the coffee maker.

Hi, in most cases it is due to the solenoid valves. But also check whether there is perhaps a calcification.

@@yt.myworks Thanks. After decalcification, i replaced the Solenoid valve and the milk dispenser coupling including the pipe. It works now for 1-2 coffees after starting the machine. But not always. Also when selecting only the milk option gives only steam! No idea what i could do more.

I think so.

Hallo, kannst du bitte diesen Fehler etwas genauer beschreiben? Wie viel Kaffee wird bei Verwendung von Kaffeebohnen gemahlen?

@@yt.myworks ich schließe die Machine mit dem Strom an . Geht normal an , ohne Meldung oder so , sobald ich auf Kaffee mit Bohnen drucke leuchtet im Display kaffeeaufsatz einsetzen obwohl es drin ist , natürlich bleibt die Machine blockiert bis ich sie mit Strom trenne , im Gegenteil wenn ich auf Kaffee mit Pullover drucke funktioniert einwandfrei ohne Meldung

?

It could be that the heater is calcified. Check the water line coming from the heater to see if it is clogged. Then try to descale the machine properly.

@@yt.myworks appreciate the response. the steam wand works fine by the way - would that still work if heater calcified?

@@huzcer I think it's possible. The steamer has its own water pipe. But it's just my guess.

@@yt.myworks thank you again. I had been regularly descaling with lactic acid but maybe it was not strong enough. I ran 50g of citric acid through it a couple of times and now water is more freely coming through the coffee outlet again.

Please search on Amazon or eBay. See my link below in the description.

Hello, you can also check the water pump but I think one of the water pipes is clogged. Most of the time it is the teflon pipe that goes directly from the heater to the brew piston.

@@yt.myworks thanks for the quick reply. I am not sure what was wrong, but I was also thinking about the water pump. So I just disassembled the pump and then put it back together, without changing / replacing anything. And it worked fine after that. Really strange. But thanks again, your channel is super helpful!

I had the same problem. I have checked all the pipes, the pump, every part of the machine. The problem was a congestion in the infuser. You should remove the stainless steel cap of the infuser and clean the surgace correctly. There you can find a ball “valve”, it can stuck by the coffee oil and grease. Just push it and try to clean it. At first I have disassembly the infuser, not a big thing and in this way you can see the other hole of the duct between the rubber o rings.

You can fill the pump with water, but it is not necessary, after a few seconds the pump will suck in the water.

@@yt.myworks It did. I was worried the aggressive mechanical movement would damage a component inside the pump, since air creates less resistance. But as you said, after 20-30 seconds, it started releasing water.

@@ignisGladius this is a positive displacement pump and can prime itself. If it does not the tiny ball may have been left out. This ball is part of the valving. A damaged o ring or damaged ball can also prevent the pump from pumping at the full rate. The vibration pump installation can affect its output profile. The output can be controlled with pulses of electricity and a pressure regulating circuit on the output. A buffer tank can be used to smooth out the output pulsations. I think this a very good device for this application. It does not have a heavy duty cycle and output is limited. It can reach high pressures adequate for its application. The on-off control characteristic combined with a return spring makes for a simple reciprocating pump with out a rototing motor. This setup lends itself to easy control for output versus controlling a rotary pump output. The latter would require a motor speed controller which is more complex when regulating output. I found an interesting video comparing shots pulled from each of the motors and it reported significantly better product with the rotary motor. I don't know whether that is Lucky or whether that is irrefutable. Depending on the pumping pressure regulation arrangement, one should be able to produce very consistent output from either device. Given the reliability and low cost of the vibration pump I think that would be the choice for most devices in lower price range.

Had the same, replaced the pump, sensor and o ring and now it works great again. Don't know which exact part broke, but it works fine again for 30 bucks

I can't say for sure, but I recommend descaling the machine that runs quietly with a special descaling agent. For the other water pump, I recommend checking if the same amount of water is coming out to rule out a defect.

@@yt.myworks Well you were right : even I thought the machine was descaled enough - two extra cycles helped a lot . Hence one is louder then the other , but it is not that loud anymore .

Hola, busque "Ulka Pumpe" en amazon.de o ebay.de y preste atención al nombre correcto de su modelo. El enlace también se puede encontrar a continuación en la descripción. No puedes comprarlos en México?

Hello, that can mean that the o-rings and ball have to be changed or the machine is clogged (calcified).

@@yt.myworks I wouldn't say so. I do the regular basis cleaning on it and as i said about the pump, it all seems ok.No compounds etc foundings. I will replace parts or the pump itself and see. I will keep you posted about it if you like. Thank you for your response anyway .

Please follow step 3 from my last video (min. 7:00), maybe that will help. Descaling recommended by the manufacturer is often not enough. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-OJWguSgyf4c.html

@@periklisgiannopoulos5273 cleanings or descaling? Big difference.

@@periklisgiannopoulos5273 hi there. This sounds like my exact problem! Can you let me know what you did and whether it worked?

Hallo, die kleine Feder auf der die Kugel sitzt sollte in einem Stück sein. LG

@@yt.myworks Danke für die Antwort. Ja , eine Teil der Feder ist auf einem Stock andere war auch drin! Wo kann man sowas kaufen? Ich brauche auch diese Plastik Kugel, die auf die andere Seite, auf die Feder kommt!

Hallo, die Dichtung mit Kugel habe ich unter dem Video verlinkt. Eine neue Feder gibt es leider nicht zu kaufen. Da sollte exakt die gleiche eingebaut werden sonst arbeitet die Pumpe womöglich nicht richtig. In dem Fall würde ich eine neue Wasserpumpe kaufen. Bei eBay sind sie am günstigsten. Achte auf die Bezeichnung, dieser muss übereinstimmen. LG

@@yt.myworks Danke für die Antwort.

@Reiner Schulte: Unfortunately, I cannot tell you that because I have too little knowledge of electronics.

Olá, se a resistência é infinita decerto a bobina está queimada.

A diode is installed inside the pump. Is that why you think the coil is defective?

@@yt.myworks thank you :)

Hi, does the water pump become quieter? If so, then a water hose is probably clogged.

@@yt.myworks no the pump doesn't come back on... when I push the ok button.. it just clicks on and off..(solenoid) it happend right at the end of the descale.. But one thing I did try was filled the distributor and I turned machine back on.. the pump struggled for a bit than started working... So I started de-scale again.. and at the same last rinse on de-scale... no pump.. only clicking of solenoid when I keep pushing ok on screen 😔

You have to test the water pump by disconnecting the teflon hose after the pump. You can put the end of the hose in a bottle to see if water comes out. But be careful, the machine is live!

@@yt.myworks thanks I will definitely try.. appreciate your time and knowledge 🥰

Ich denke nicht dass die Wasserpumpe nach zwei Jahren defekt ist. Ich vermute eine Verkalkung in einer der Teflonleitungen. Das ist zumindest der häufigste Fehler. Meistens ist diese von außen zu erkennen wenn die Schläuche nicht mehr durchsichtig sind.

@@yt.myworks Oja die Schläuche sind schon noch durchsichtig,vielleicht ganz leicht gelblich. Im hinteren Schlauch der vom Wassertank kommend , sieht man das Wasser in dem sich kleine Luftbläschen leicht hin u. her bewegen, aber es wird nicht weiter transportiert. Daher ist mein Gedanke auf die Wasserpumpe gefallen. Momentan sind über 7000 Café´s gemacht worden.lt. Zählwerk. Ich filtere Brunnenwasser mit einer Laica Tisch - Wasser-Filter Kanne . Es besteht kein anderer Wasserzugang. Zeitweise nehme ich auch gekauftes Wasser. Wäre schön wenn Ihnen vielleicht noch was Einfällt was es sein könnte. Schönes Wochenende gewünscht. Und danke für die schnelle Antwort. Sehr nett.💐 Schönen Gruß aus Wien - Umgebung.

Hallo, ich habe die ganz dünnen Schläuche gemeint aus Teflon. Diese verstopfen sehr schnell. Okay bei 7000 Kaffees kann natürlich auch eine Wasserpumpe kaputt gehen. In diesem Fall ist es keine schlechte Idee als erstes die Pumpe auszutauschen.

Hallo, welches Modell ist das? Meinst du Düse für den Wasserbezug? Es könnte sein, dass das Magnetventil vekalkt oder undicht ist und nicht mehr richtig schließt. Am besten du lädst ein kurzes Video hoch, vielleicht fällt mir dann etwas auf. LG

@@yt.myworks Hallo, das habe ich soeben gemacht:) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n3rcAJyxz4s.html

@@peterpan8355 Hallo, das hört sich an als ob eine der Dichtungen am Brühkolben oder Brühgruppe nicht halten würde. Beim komprimieren von Kaffee-Puck entweicht die Luft irgendwo. Wie viele Kaffeebezüge hat der Automat bereits? Sieht ziemlich neu aus.

@@yt.myworks Okay, dann werde ich mir das mal genauer ansehen, danke für den Tipp! Das Gerät ist 2,5 Jahre alt, durchschnittlich 2-3 Kaffees. Lass dir ein Abo da :)

The O-ring 5/2 mm should be replaced.

@@yt.myworks I'll try it. I might have one downstairs in my AC o rink kit, (the green ones). If i get time i can swap out the parts with my working pump to double check if that's it. It's definatly expanded but the seal feels ok but it might be slowing the oscilations from being a bit squished in there. Funny how the pump only works one way round even though the power is AC.

Przyznaję się że też jeszcze nie wymieniałem grzybka na nowy. W nowszych modelach chyba ich nawet nie ma. Najważniejszymi są jednak uszczelka i ewentualnie kulka które należy wymienić. Sprawdź następnie czy nie jest w którymś miejscu zatkany przewód wody lub sam bojler. Często pojawia się w tych miejscach kamień kotłowy. Włącz płukanie z roztworem odkamieniającym co parę minut.

@@yt.myworks Ekspres z drugiej ręki, rok temu czyściłem wyciorem wszystkie przewody, wymieniałem uszczelki w zaparzaczu i elemencie który wciska się w zaparzacz oraz przewodach od bojlera do zaparzacza. Przez dwa odkamieniania wypadały duże grudki kamienia, teraz jest już spokój, odkamienianie robię często, ustawiłem sobie że mam najtwardszą wodę (muszę sprawdzić z ciekawości jaką faktycznie mam, wodociągi, nowy dom i nowa nitka wodociągowa na mojej ulicy). Zauważyłem natomiast, że po kilkunastu godzinach nie ma wody w przewodzie między pompką, a bojlerem. Na logikę, chyba woda powinna być cały czas, może puszczają oringi na przewodach lub wspomniany przez ciebie oring w pompce? I chyba przez to jest taki efekt po włączeniu ekspresu: syczenie, prychanie, bulgotanie, para, dopiero chwilę później zaczyna lecieć woda i zaparzanie kawy jest OK, a z każdą kolejną kawą jest lepiej. Potwierdzasz, że woda nie powinna się cofnąć z przewodu między pompką, a bojlerem? Mógłbyś mi polecić jakiś dobry, sprawdzony odkamieniacz? Zamierzam wymienić całą pompkę na nową ponieważ cena jest śmieszna ;) wymiennego grzybka nie potrafię znaleźć, a jest już twardy jak ten oring przy kulce.

Jeżeli słychać syczenie to przypuszczam że będzie gdzieś nieszczelność w górnym tłoku zaparzacza. Wtedy dostaje sie powietrze i woda wędruje z powrotem do zbiornika. W tym przypadku można wymienić uszczelki lub całą część na nową.

I buy most of the new components on ebay or amazon, as well as the "O" rings. You can see the size on minute 3.10 in the video. Also I would recommend you, to change the little ball in the pump.

Thanks. I was able to find some orings and balls on EBay. Hope they will work. Do you know where I can get the plastic part that goes through the pump for the Francis Francis X7.1? Thanks

@@c.patricksadowski9959 ​ Unfortunately I don't know where you can get the plasic part because I didn't disassemble the portafilter yet.

@@yt.myworks where can i get you big o ring that seals the plastic

@@untitledduck9675 You have to survey the O ring and search for it on ebay or amazon.

Se la sfera non è troppo piccola (circa 4 mm), è possibile sostituire solo l'o-ring.

Hello, I don't remember exactly, I think that was POM.

@@yt.myworks I swapped the gasket o ring with new one, same size but it doesn't pump water now, your video after the 9mm o ring was installed, the circle plastic, does that circle plastic with the divot side face the o-ring or the other way around?

Hello, the circle in the plastic should point to the o-ring. But it should also work the other way around. Check everything again exactly.

@@yt.myworks it took me while to find out that it was air pocket in the tube that cause no water.

Trudno powiedzieć, przeważnie jest głośna kiedy nie dostaje wody. Musisz sprawdzić wężyk po wężyku w którym miejscu jest ewentualnie zatkane. Uwaga! Woda może być gorąca i pod ciśnieniem. O niebezpieczeństwie z prądem chyba nie muszę wspominać.

@@yt.myworks Nigdy nie naprawm urzadzen gdy sa podlaczone do sieci energetycznej :)) Czy Delonghi maja wbudowane zasialanie wewnetrzne oparte na beterii ze o tym piszesz? Czy powod jest bardziej, hmmm, amerykanski? :)

Oczywiście to drugie ale ostrożności nigdy nie za dużo, już sam się o tym kiedyś przekonałem. Przy szukaniu błędów podłączam zasilanie w urządzeniu wielokrotnie i można się szybko zapomnieć ;-)

@@yt.myworks No u mnie ten blad jest ciagly. Moge jedynie pusic ciepla wode, trwa to okolo 5 sekund. Dwa zauwazylem ze jak w tanku konczy sie woda to nie daje bledu zeby uzupelnic tylko pobiera dalej. Moze ta informacja pomoze w okresleniu co jest nie tak. I dzieki za odpowiedz. Super kanal, przydalo by sie wiecej filmow, szczegolnie z innymi modelami np De'Longhi Eletta, taki jak moj :P

Sprawdź czy prawidłowo podłączony jest "flowmeter", to te okrągłe, białe urządzenie. Chodzi o kierunek obiegu wody. A z pojemnikiem na wodę to czy pływak nie jest zablokowany.

Did you also test the pump ? Make sure it works by itself. Also some pumps have fuses infront of them (You can see them at the wires that go in the pump. Measure the fuse too.

I would check for blockage first. Most of the time, the pipe that comes out of the heater is affected.

@@yt.myworks just left it on for a little bit and it magically started working again. Strange. Gonna descale it a couple times, and hope for the best. Thanks for the quick reply.

@@yt.myworks Also, just replaced the o-ring and the ball. And only few drops came out. But steam/water is working. Which pipe is that, please? Maybe use stronger decalc solution? Thank you

@@goozoon this is the pipe that comes straight up from the heater. Most of the time the calcification is visible when the inside of the pipe is white.

@@yt.myworks I have two Magnificas and in first i changed the o-ring (i described here) and nothing changed. So i saw your another video and tried to decalc with rinse technique (my in-built decalc process pushes water only via vaporises head only, not via coffe makes nozzles, so it decals only that left pipe only. This i have on both machines, i dont know why) So i put some concentrated decal solution and made rinsing as you described. And after 3 rinse all is good now. I made the same on second machine, without changing o-ring and it makes coffee now as it should. Thank you. First machine is leaking water from tank when making coffee or rinsing. No leak when doing nothing. So need to check the valve on the tank. Maybe calc, too

Ja, mehr ist nicht, eventuell noch die Kunststoffkugel falls verschließen.
