zanussi washer/dryer?

ck thanks for your reply i have checked the brushes they r more than 10 mm no water or foam went in the pcb also i checked the wiring loom to motor with a meter motor loom shows continuity to the pcb (all wires from connector on motor to pcb while connected on both ends) i put the machine into diagnostic mode and it oasses all tests upto where it checks motor at 50 rpm to 250rpm but it fails the next step in the diagnostic mode where it is suppose to run on full spin speed instead what happens is that as you begin this full motor spin test first the drain pump starts and keeps on running and never stops so because of the drain pump constantly running the machine does not get a chance to check the full spin speed so thats why in my previous questions i had asked for your advice on how to bring the adjustment of the electronic pressure switch back to original position as i had mis adjusted it by mistake by turning the plastic cross head screw at the back of the electronic pressure switch because drain pump when starts to run at the begining of the cycle and keeps on running forever which prevents the machine from performing any further also can you advise me where i can get a cheap electronic switch and the main pcb as the new electronicpressure switch is reasonabely priced at 32 pounds but the pcb is very expensive thanks for all your help i thaought if i can get these two parts cheap i might aswell replace them and that might solve the problem what do you reckon thanks again.
