Miele CM 5300: Milk foam splashes and spatters

Hello,

I have been using a Miele CM 5300 for some time and often make cappuchino. Leidr abruptly the milk foam formation no longer works properly. Milk is sucked in, it comes first foam and then it splashes and spits only. Steam is obviously there.
I have cleaned everything carefully, including the milk foam cleaning program (before I always just rinsed) and the machine 2x new decalcified. No change. There is nothing in the milk foam valve (where the hose plugs in), it has passage and is clean. The line and the two coupling pieces are also clean and free.

What can I do to make the machine foam again?

Thanks

Hello, it can have several causes that your Miele no longer makes milk foam, the most important you have already worked through so that you should now look at the ceramic valve that sits behind the water tank. On the ceramic valve sits an air intake valve, the clean.

Thanks for the quick reply.
I have to disassemble the housing for this, right?
I had not yet disassembled the Miele, only what was necessary for cleaning.

Is there a sketch?

Thanks

This is pretty simple but proceed carefully. Remove Torx screws and then remove the top cover then you can push the side panels back a bit and then remove them.

Thanks, I'll tackle that on the WE :-)

It works again. The red rubber valve under the top cover, right next to the water tank, was seated shut. The opening is also tiny.

Thanks for the help.

Can I buy this air intake valve as a spare part?
What is it called exactly?

I can't find all the Torx Screws! There is one vertical screw at the back right corner under the bean cover and another horizontal going in from behind the water tank. After that I'm stuck?
Can anyone help? And is it possible to obtain a service manual anywhere?
