Siemens EQ5 Macchiato

Hello,

sorry first a sorry in the round falss I do something wrong am absolutely new here.

Now to my problem:

I have a Siemens EQ5 Macchiato.

Treser is no longer dry but has become increasingly wet.

Now wanted to replace brew group seals (piston seal and the two on the blue inlet nozzle) - I also did - reinstalled - water no longer ran out the front but only below in the brewing tray.

Second (fortunately I have ne second brew group) reingebaut - machine ran normally - water and coffee out the front.

Then the 1st brew group taken - old piston seal reinstalled - the same condition everything ran into the drip tray.

Then the 2 small seals on the blue inlet nozzle - here again the old installed and tried again.

Now the brew group also runs normally again and it comes out the spent grains but also wet again.

When I installed the new seals and the water ran into the drip tray, the spent grains were completely dry - but I think this was due to the fact that the water did not reach there or ????.

My question - what can be the reason =???

Are the seals wrong although bought in the local store ????

Why is the spent grains so wet in the meantime.

Please for many and understandable feedback - thanks already in advance.

greetingsMarkus
