Milk frothing problem with Siemens EQ.6 Plus s100

[OdioGenerisHumani]

Hi all,

My Siemens EQ.6 Plus s100's milk frother system suddenly stopped working properly and I cannot find my answer elsewhere online. I've tried a couple of things but it has not yet solved it so any further tips would be much appreciated!

Some points:

• The milk is being sucked up into the tube, but nothing comes out
• I clean the machine weekly and I've ran a cleaning cycle as well as multiple milk system cleaning cycles. When I clean the machine I also take off the cap at the front and the two plastic parts where the milk and coffee are being dispersed from
• The same milk is being used as always
• The tube I've bought a couple of weeks ago and is fine (no leaks)

Any help would be much appreciated!
