WASHING MACHINE WF80F5E0W2W

Hello, 

Have the washing machine WF80F5E0W2W for like almost 9 years now. Pretty satisfied and no problems so far.  A few days ago I came up with this problem:
I hit play, machine starts working, I hear the water running, but after like half a minute the machine never starts to spin. In the screen the red key is blinking non stop.  

I've tried the following: plug and unplug, stop and restart another program, empty any water on the bottom right pipe and clean the filter. Once I got it to start successfully, but that was it, keeps doing it again again till now.

Does anyone know how to fix this or what the problem is and if I'll need a technician?

Thank you.
