EQ5 milkPerfect - won't start making coffee

First of all, thank yall for providing help on this forum, I appreciate each one of you! Happy to be here.

I have searched for the issue I have with EQ.5 milkPerfect, also checked the user manual, but so far no luck for me. Let me describe the issue:

Eveyrthing works perfectly fine except for the machine won't start making coffee, so nothing happens after I press start button. I only get quick flash from off/steam/start buttons and that's it. Machine won't even start grinding or whatever. I did calc'n'clean twice without issues, hot water/steam works just fine.

It's those 3 buttons underneath the coffee strenght knob that are flashing. Anybody had similar issue or could guess what could be the cause?



Thanks again!
