Question about Miele Coffee System

1 Answer

Lack of pressure from the steam wand used for frothing the milk.

This is a Miele CVA620 model coffee machine. The pump appears to still be working (we can hear it), but the steam spout does not create enough pressure to froth the milk. We've expelled the air & cleared the nozzle. There is still some steam coming out, but lacks enough pressure - so it appears not to be a complete blockage, but an issue with the steam pump.

Hello Juneyjune,
These coffee systems have a series of small rubber 'O' rings that tend to crack from condensation over time causing your low pressure problem.
The 'O' rings are connected to a heater that looks like a horse shoe mounted in back of the grinding unit.
I would recommend contacting Miele technical services. They can have a technician come out to replace the 'O' rings or you can order them from the technical services rep if you know someone that can replace them for you. Just be careful. These machines operate off of 220 volts and that is no fun to get shocked by. I have been many times with this machine

Good luck!!!

How do i use the steam wand to froth milk


The steam wand to froth milk, you need a certain amount of milk in the cup first, then if you tilt the cup a little towards you, push the steam button and "it should froth your milk right up", but if that doesn't work then I don't know.

Froth


If you are getting steam out of the wand I suggest you practice and work ha and to learn how to froth up the milk. The machine does not froth up, it is the operator who does. You basically need to keep the wand just below the milk level and keep moving very slowly up and down always trying to stay below the milk level. If the container is wide you may need to swirl as you moving.

Miele built in. Steam but no froth


Sounds like the venturi tube could be blocked. My model is a CVA 4085 and I can take the assembly out that sucks in the milk, mixes the air and stem and spits out frothed milk. If yours is similar, see if you can can reach the top of the milk outlet tube and rotate the ring around it anti-clockwise (if you were looking up from the bottom) and take the whole assembly out. If you have never taken this out, disassembled it and rinsed everything out thoroughly under a running tap now is a good time to do it. Then check the venturi tube: the clear (ish) bendy plastic tube that that points up and has a cone with a hole in the top. If that hole is blocked you won't get very good froth. If you can't clear it with warm running water then VERY CAREFULLY use a small needle to push through the hole at the top, then put everything back together.

Good luck.

The milk frother is not sucking milk from the cup... it appears that the steamer is working as if it is steaming the milk. Any ideas on why the frother tube is not sucking any milk up?


it is clogged with dried milk. Remove the frothing wand from the machine. now press milk froth. you should get a ton of steam blowing out of the hole where the frother used to be. Your frother comes apart for cleaning. pull the chrome tip off, pull the 90 degree fitting and the black milk suction tube off, if it is really dirty you can soak the disassembled frother in hot water with a cleaning tablet. ( the small ones you drop in the brew unit, not the big descaling tab.) also, there is a clear tube with a point on the end of it sticking out of the frothing wand. this is an air admittance oriface. it allows air to enter the hot milk stream and make it frothy and bubbly. if it gets clogged, you will get hot milk but no froth. Your machine came with a spare one in the parts kit.

My steamer wand has an awful odor everytime I try to steam something! I have cleaned it (even soaked in baking soda!) and the problem won't stop. Anyone else have this problem?


This is a common problem for the commercial espresso machines, Due to lack of cleaning of the steam wand after they finish frothing milk.
The milk flows back to the boiler and the water gets contaminated with milk.

Does the steam smells like rotten milk? If the answer is yes, you have contaminated water and or lines.
If not may be there is a lot of IRON in the water.

Run a descale cycle.

After you are done frothing milk, wipe the steam wand with a wet towel and open the steam valve for 2 seconds, close it and that's it.

Why won't my starbucks serina froth milk. Just stopped doing this all of a sudden. I descaled, the little hole in wand isn't blocked. The milk heats but no froth.


This problem developed on my Sirena machine about a week ago. Stopped frothing milk, but still produced lots of steam. In fact, it was splattering milk everywhere, just not producing foam. Cleaned the steam wand (including air intake) and descaled the machine (even though its only 3 months old) to no avail. Called Saeco customer support (1-800-933-7876) and the very helpful rep immediately identified the problem. Inside the Panarello steam wand is a removable plastic tube. The tip of this tube should protrude about 1/8" beyond the end of the steam wand. Mine was not. Using the eraser end of a pencil, I pushed the inner tube downward into position and, voila, I now have froth again.

Weak steam flow from milk frothing wand.


This is usually a sign it needs a de-scale. you can get a de-scale solution from most coffee machine retailers. Vinegar can be to harsh and ruin your seals. After frothing your milk make sure you let some steam through without milk to clear milk that can be sucked up wand. You can get cleaning instructions of Saeco web site. Good luck

I have a expresso machine ESP6. it is not letting out enough steam or frothing milk. what's the problem and how to fix it?


The steaming wand's tip gets gunked up with milk so make sure to clear that with a needle first. Make sure the machine is fully heated before using the stream function (should have an indicator light). Typically this model will expel water first, then a low pressure steam. After about 30 - 40 seconds it should produce meduim pressure steam. Make sure the pump is making the proper clunk, clunk sound or it could be failing. Also, the steam wand arm may be obstructed and descaler solution will have to be used to remove the deposits. Hope this helps.

Weak steam stream


Have you descaled the unit? If so, milk might have been sucked up into the frothing wand. Take off the exterior covering of frothing wand...rinse it well.

I have used a large paper clip...straighten it out. Take the straightened out paper clip and insert it into the metal stem gently and move it around inside the metal stem. This may dislodge the blockage. Before putting the exterior cover back on, turn on the the frothing wand to see if it has improved the power of the steam.
