Did you dry the PVA before/during use? Moist PVA will easily get grinded by the gears what will result in a blockage.

Yes i did, its dry.
but most interesting thing is, when i use the function filament unload it retracts normaly. But when I start to print a model it just stays blocked in extruder after the first layer.

I belive my problems lays in Filament Sensor. Sometimes when the filament(PVA) is inside the extruder it just shows 0, after i reset the printer.
When i tried to test the sensor with allen key or with some ends of other filament (also tried it with PVA) it always works perfectlly. it always turn to 1.
