AEg OKO_lavamat stopped working after ceaning the filter / pump?

The washing machine stopped working before spinning, i gathered that it must be the pump since it worked if i let out the water manually. I cleaned out the pump as there was indeed sludge inside the 'fan' compartment. I have not replaced the pump motors. But now the machine does do nothing. I can set the program and the door clicks locked when starting, but nothing happens on none of the programmes. i hear a faint buzzing noise from the PCB, but this may be normal. Any ideas? is it possible that failed pumps block the machine completely?
Regards,
Filip
