Ariston Margherita CDE 12 X not filling water

Hi,
Some days ago, my washing machine started filling water very slowly – very small amount of water, although the tap was fully open. As a consequence, each washing cycle would take hours.
I pulled out the washing machine and find out that the water rubber pipe was bent.
I fixed it and turned the washing machine on: the red light would turn on, a little ‘click’ but then nothing happens – it doesn’t start filling with water.
I tested the electro-valves and I have seen that:
– Unplugging the supply wires from the 3 electro-valves, I measure around 50V ac in each supply wires pair (electro-valves are 220V ac devices). It seems ok.
– When I plug the supply wires on the electro-valves and turn on the washing machine, I measure 0V across electro-valves terminals – the all 3 valves. And no water in at all.
– With supply wires removed I measure the valves resistance with a multimeter and they all had a resistive path (I don’t remember how much, but can check if relevant).

So my question is: are the electro-valves defective? Should I order spare parts and replace? Or could it be the electronic module (or other)? About 1 year ago, I had to replace the module by a new one due to some other problems. I acquired it from Ariston and it has always been ok since then. So, this is a relatively new module.

Appreciate your feedback.

Thanks
Joao
