To repair a clogged washing machine drain, remove the drain pipe that connects the washer to the home's plumbing, clean it, and use a plumbing snake to remove clogs located inside the main drain pipe. Flush the drain lines with hot water to remove the remaining debris.
- Remove the drain pipe
Locate the drain pipe on the back of the washing machine, and remove the pipe. The pipe typically connects to the wall and to the lower corner of the washing machine. Soak the drainage pipe in a solution of 2 tablespoons of chlorine bleach per gallon of water, and then flush the pipe with hot water.
- Clean the drain and drain pump
Examine the drain pump for small items, such as socks and debris, and remove any visible items. Clogs that are located deep inside the plumbing are removed using a plumbing snake. Insert the snake into the affected drain until it meets resistance, and twist the snake to catch the debris inside the pipe. Pull the snake out of the drain to remove the clog.
- Flush the drain
Reattach the drain pipe connection that leads from the washing machine to the wall, and run an empty cycle using hot water to flush the drain pipes.
