Pressure switch fault will not let water fill.

Hi Andy I have read through your faults pages but not found the same fault hope you can help. I have a zanussi zwh7122j PN 91490492501. I have just moved, when I had to move the washing machine installed drum bolts and moved on it side in the car. When I installed in the new house the machine would not fill with water. Checked the water supply, which is good checked filters which were clean, checked the solenoids with a meter and they were both good, checked the pressure pipe and chamber which were both clean and good, when I take the pressure pipe off the switch and operate with my mouth the machine begins to fill so i connect the hose the machine fill to the correct level and begins it wash cycle, at the end of the wash it pumps all the water out but will not fill for the rinse. Took the pressure hose, chamber, and the rubber connector to the bottom of the drum off also checked the main filter all was good. So bought a new pressure switch from zanussi fitted it but the machine acts the same, I havent operated this one by my mouth, have filled the drum with 3 liters of water and drained as a reset for the pressure switch but its still will not fill unless I put the old switch back on and operate by mouth. All the progams seem to work except from the fill. Please help if you can cause im at a complete loss. Any help very much appreciated, good site by the way. Warren.
