Hello,
I will stick to the topic so as not to add a new one, I have the same coffee machine and during brewing I have water from the frothing nozzle and after brewing coffee for some time from the main nozzle. Is it possible to do something about it or is only the service left?

Hello.
I, in turn, have a slightly different problem with this machine.
Namely, the water does not fly or it flies very very faintly. Coffee cannot be made.
I suspect he's turned a stone somewhere inside. I got everything I could, but it didn't help. I can't get under the dome, although I unscrewed all the screws (found 4). I took the valve off the frother.
If someone has a diagram or knows how to start this machine, please help.
greetings

The duladr coffee machine is descaled with a descaler, not by disassembling to the first factors. If the water is flowing a little, pour the descaler into the container and run the water through the coffee maker with the steam nozzle and the portafilter.

witak allow me to pin the thread
So I have a problem with this express that when you turn on the heater, after a few seconds, water begins to drip from the place where the flask is. I will add that I recently dismissed it for cleaning because the pressure was poor and the coffee did not fly, after descaling it improved a bit, but this problem occurred.
I am asking for help which may be the reason

nioop · Answer

- Pump valve - Head valve - Lower part of the boiler - Boiler valve chamber contaminated Added after 0 : - Pump valve - Head valve - Lower part of the boiler - Boiler valve chamber contaminated

tmjumper · Answer

Can I somehow check these elements myself?

nioop · Answer

naturally..
Ie we buy a descaler first.
And of course, we descale (I repeat it many times here, but I will repeat it again - No vinegars, acids, lemons or bananas, ordinary descaler for PLN 2)
Then unscrew the strainer in the head .. (When the coffee machine cools down) and there will be one more screw under the strainer for a flat screwdriver .. Unscrew it carefully, because there will be a rubber plug on the spring .. - Clean the plug and gently stretch the spring ..
We twist everything and check .. It should help - If we fail, we will continue to instruct

But it should work

Hello. This is my first forum post, so please be understanding if I do something wrong. I would also like to connect to the topic so as not to clutter the forum. My problem is that in the same machine, steam has stopped coming out of the frothing nozzle. Nothing happens when you turn this knob. I tried to descale the machine but it didn't help. Any idea what else I could try?

nioop · Answer

Sure we have an idea at 99% you have a faulty steam valve. It is hard to fix, in my opinion the only sensible idea is to replace it.

Jardo · Answer

I am asking for advice, looking for the cause of the leakage of my DeLonghi express, I came to a frayed hose between the pump and the boiler. (A hose with brass rings at the ends). Can you fix it yourself? I would shorten the tube, but I don't know how to put this unfortunate wedding ring in a new place. Where can I buy such a ready-made hose online?

The tubing rubbed against the sharp edge of the metal skeleton from vibration.

nioop · Answer

A frequent case, I personally put a thicker rubber hose on it, which eliminates the risk of a fault and thus mutes the operation of the coffee machine. The only sensible repair is to replace it. Where to buy ? Please use google From what I can see there is a lot of it ..

Jardo · Answer

Surely there is a lot of it, the question of using the correct name. If I found it in googles, I would not ask for help.

nioop · Answer

I used the name DeLonghi hose, then in the first link I saw:

Jardo · Answer

Thanks! the key word is teflon tubing and I was concentrating on the pressure tubing.

teleserwis · Answer

And I have such a case, the express makes half a cup of coffee instead of a whole, of course set to the max, for some time it has been happening, it was descaled, of course, where could the cause be?

nioop · Answer

No offense, however, please read the instruction manual .. The machine will make as much coffee as the button is pressed.

tommyv1 · Answer

I also have a problem with water dripping around the flask. I wanted to try this method, but after removing the strainer, I do not have a screw, just like in the picture ... how to get to this screw for a flat screwdriver? I would ask for help.

adrianna29 · Answer

tommyv1 we probably have the same maker and the same problem. I don't know how to get to the coffee machine either. My husband tried in advance, but you can't really walk there and we didn't want to spoil it. It would be good if there was a solution, because cleaning the unscrewed strainer only helped in the short term.

Hello. I am connecting to this request because I do not know what to do next?

maglo2710 · Answer

Hello, did you manage to repair the coffee machine? I have exactly the same problem and the exact same machine layout. After removing the strainer and the gasket, it is impossible to get anywhere else to the system.

zbignieww · Answer

Remove the cover. Unscrew the 2 screws at the top of the back of the housing, tortex with a hole, after removing the water tank, above it you can see a cross screw, identical in the hole on the other side of the stock, unscrew them and you can remove the cover. I had a broken wire above the black valve above the flask, and this valve has a conical spring with a plastic mushroom, it was bent towards the broken wire.
