Probably the vibrating water pump is the problem.
It might be full of scale and it can not create any pressure or create less pressure than 9-10 bars or it is completetly damage and need to be replaced. ( you can remove the pump desasemble it clean it from scale and dirt and try it again but this requires very good expert skills)
For plastic ot other tubes no need to replace, just use a steel wire or a screwdriver in order to remove any scale or dirt inside them,

First we sugest to perform a descaling of the machine two times one in one day and another the second day and try again this will help the machine very much no matter what is the problem .
Second you should try to reduce by little the quantity of the grounded coffee used. Aprox you should use 7 to7.5 gr of coffee. If you try to use about 6 to 6.5 and you have the coffee runing out from the machine like in 25 sec you have about 30 cc of water.
Then try also to clean the group shower which it can be ansrew by one cetrer screw (and if you can you can open the machine and remove to clean also the coffee group solenoid valve). Both the valve and shower can be full of dry coffee that can blocked the way of water coming to the grounded coffee.
If you manage to clean everything above and the machine work ok so from now on in order to avoid the problem again try to flush water from the group many times without any coffee. With this is like you wash the group shower and valve from any remaining coffee.
Good luck
