Siemens EQ5 Coffee Maker: Poor Milk Frothing - Causes, Cleaning & Descaling Solutions

Question

Hello The coffeemaker began to froth the milk poorly. I did descaling and cleaning - nothing helped. The nozzle is clean. What could be the cause?

Lukasz3232 · Answer

I have not had contact with this Siemens, but in every coffee machine I have dealt with, there is a small air suction opening in the foaming nozzle. It is the air that is sucked in from the outside and forced into the milk by the rush of steam that creates the foam. The opening is small and often clogs up, probably the same for this case.

Beti240 · Answer

Thank you for your answer. Unfortunately, it is probably not a question of the opening, everything is clean and free. I have the impression that the milk from the spout comes out with less pressure, but what I can get from outside is not clogged. What else could be the cause?

Hello. Could you describe it more? running full stream? splashes? more details. Regards

Hello. I have the same with Eq5. The espresso machine and the steam wand actually does not produce froth, it heats the milk. It always worked well and I enjoyed a very good cup of coffee with thick foam and suddenly something changed. Is it the fault of the leakage, maybe the O-rings to be replaced? I disassembled the nozzles many times and put them together, washed and cleaned so nothing could be clogged there. Any suggestions for solving the problem?

dugass · Answer

Hello. The problem with milk frothing in the Siemens EQ5 has been solved a thorough washing and rinsing in hot water with washing-up liquid helped. Of course, the entire nozzles should be dismantled and each element rinsed. There was no visible dirt in the nozzles, but after rinsing it dry and folding the nozzle, the machine made a thick milk froth again. It was described in the manual, but somehow I did not read it greetings

tgamalski · Answer

For me, after 1.5 years of use, it stopped foaming (it worked as just a heater). I dismantled this mechanism by washing and blown it thoroughly. The most helpful thing was to clean the rubber stopper on the top of the frother, there is a small hole in it that I gently pushed through with a needle. After that, it all worked out perfectly.

dugass · Answer

Exactly. This rubber element must have a tiny hole that clogs a lot and the frother does not work as it should. It's best to push it through with a needle, but not enlarge it.

andym2 · Answer

Thank you everyone for the hint. The confusion with me was of course a small plug with a hole, as it turned out later. The hole was clogged and made of foam thread - and now it is like new after cleaning (wiping it with a needle).

Hello. In my case, in the Siemens EQ.3 express, it was necessary to clean the socket on which the milk filling tube is placed. There is a tiny groove through which air enters the tube. And it is the air that produces foam. If the groove was clogged, the milk only got warm.

Odin · Answer

Hello,
Old topic, but I have the same problem and I also decided to clean the rubber stopper with a hole, but I probably accidentally enlarged this hole because now it was as if it was getting too much air.
I recorded a video:

Is it enough to replace the nozzle for only PLN 45 + shipping ?

Could anything else be wrong?

huntersq · Answer

I have the same problem as my colleague Odin who recorded the video, the rubber stopper is replaced, but then the same at the beginning, the milk flies properly for a moment and then splashes as if there was too much air.
Any ideas what I can do?

Odin · Answer

Have you washed and cleaned the other elements of the foaming system well?

huntersq · Answer

So everything was thoroughly cleaned and washed in hot water with some washing-up liquid

Odin · Answer

It's a strange thing, when I was looking for a solution, people, apart from the nozzle, also wrote about checking the patency of a small hole in a plastic element (probably the one in which the rubber soul is mounted). Try to blow it, if it doesn't help, I don't know, maybe some element deeper in the device. I'm just a user

huntersq · Answer

I solved the problem for those who were looking for a solution, this element from the photo was responsible for all the confusion. I'm not sure, but it's probably called a multi valve. For me, after undressing, one hole was clogged, I pushed this hole through and the coffee machine works like new.

porter6 · Answer

Hello, I have a similar problem, the milk frother started to froth the milk poorly. Model Siemens EQ.5 Macchiato Plus TE515209RW. In fact, there was no foam at all, just milk. Replacing the O-rings did not help. After pushing the rubber nozzle with a needle, it started to splash very much, like in the video ( Washing the entire system in water with dishwashing detergent does not help.

Odin · Answer

If you pushed the needle and it splashes more, like I did, you enlarged the hole, so in the first order, replace this element with a new one. Maybe by the way you will solve the initial problem, if not, you will have to keep trying

porter6 · Answer

Did replacing this element help in your case? By the way, the second question, do you know how to get to the dispenser (from one I noticed that less coffee flies)

Odin · Answer

For me, the exchange helped, everything works ok. I don't know how to get to the dispenser, so far I didn't need to ?

porter6 · Answer

For testing, I glued a piece of duct tape to the nozzle and made a small hole with the needle.
It helped. Foam may not be what it used to be, but it's already good. Now I know that replacing the nozzle should bring the expected effect.

If anyone knew how to get to the dispensers, I would be grateful for the information ..

icexx · Answer

dig up the topic a bit. did you also splash out a lot when frothing the milk? It looks like you are frothing the shot and not foaming the milk.

Odin · Answer

You mean this effect: If so, it was the nozzle's fault

icexx · Answer

This is exactly what the effect is about. But the nozzle was clogged or is it that rubber band with a tiny hole? and when frothing the milk, was there no steam coming out of the brewing unit lid?

Odin · Answer

This rubber with a hole is the nozzle: in my case it was clogged and when I tried to open it, I accidentally enlarged the hole and it seemed to be taking too much air. After the exchange, everything is ok, I don't remember the pair.

amigoos · Answer

huntersq can you give something closer to how did you clean this valve?

comin · Answer

I'd love to find out too.

nicklasbringnielsen · Answer

I have the same problem with my eq500 classic. I am a bit confused by which nozzle and rubber band etc. We are talking about. Is it the entire frothing system or is it the visible outside part?
