Washing machine prodcts do cause blockages within the gully, this is caused by the powder and fibers in the clothes. Grease from washing your plates etc also cause blockages, this builds up over time.
The bast way to clear the blockages in the gully is to use a rod with the black disc plunger on, run the tap and plunge, this should clear the blockage. Check the next chamber to ensure you have not caused a blockage further down.
