Water leak after replacing water valve

I replaced the water valve on my Fridg FRS6HF6JSB0. The new valve uses the high tech pressure connection for the tubes. Not so high tech because a couple of the tubes are leaking. I"ve pushed them in more, but still seams to have a slow leak.

What do I do?

There may be some kind of leakage in the pipe.
you can call the technician.
