How can i repair my Bosch WFB 1605 programme selector?

Almost certainly not a problem with the programmer.
Check out simple things first:
Check the filter unit for blockages.
Disconnect pump from sump hose and check for obstruction in either item.
Locate the pressure switch - a round item about 3 inches across. Its an air operated switch which tells the machine water has reached the correct level. Disconnect the rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty.
Also possibly problem with the heater or thermal cutout?
