Bosch washer #2460 signas that water tap is closed, checked the hoses and screens

I am not sure why but there are 2 posts for your question. This is a duplicate of my original answer:
If you have checked the hoses and screens then the most probable failure is the inlet water valve. I suspect that one of the electrical water valve solenoids has failed. If you using cold water try a warm or hot wash. If your using hot or warm try a cold wash. I am not sure on this washer if there is a mixing valve but may front loading washers have mixing valves that mix hot and cold water simply to help dissolve the HE type soaps. If changing wash temp makes no difference then a continuity check for inlet water valve coil resistance will have to be performed with an inexpensive ohm meter. If there is no continuity the solenoid has failed and the inlet water valve will have to be replaced.

This unit appears to have 2 inlet water valves one for hot and cold and one for just cold that is used for diluting soap. You will need to check all 3 solenoids for continuity. The inlet water valves are items 5 and 6 of this picture:
