Preventing future blockages is far easier than clearing a flooded pipe. To keep your drainage system clear, perform a monthly "maintenance wash" by running the machine empty on its hottest setting with a cup of white vinegar or a dedicated drum cleaner. Always check pockets before loading laundry, and consider using a lint trap or a mesh filter on the end of your drain hose if you have an older machine. Switching to high-efficiency (HE) liquid detergents can also reduce the amount of solid residue left behind in your plumbing, ensuring that your machine continues to drain efficiently for years to come. blocked washing machine drain pipe
