Here are general instructions for replacing a washing machine drain hose for planning purposes. Keep in mind your steps my vary depending on your machine, include the necessary tools and materials. If you’re unsure, always contact a professional.
Typically, washing machines remove wastewater through a flexible drain hose made of corrugated plastic. One end attaches to the washer’s drain outlet, while the other routes to a standpipe, laundry sink or other approved drain.
Step 1: Turn Off the Power and Water
Shut off power to the washing machine at the circuit breaker to reduce the risk of electrical shock. Turn off both the hot- and cold-water supply valves as well.
Step 2: Move the Washer and Prep the Area
- Carefully pull the washing machine away from the wall to access the back panel.
- Unplug the power cord.
- Place a towel or shallow pan on the floor to catch any remaining water in the hose.
Step 3: Remove the Old Drain Hose
- Locate where the hose connects to the washer’s drain outlet.
- Loosen the hose clamp using a screwdriver or nut driver.
- Slide the clamp back and gently twist and pull the hose off the outlet.
- Detach the other end from the standpipe or drain.
Step 4: Prepare the New Hose
- Measure the distance from the washer to the drain to ensure the new hose is long enough.
- Avoid cutting the hose unless the manufacturer specifically allows it.
- Keep in mind that most drain hoses are designed to be used at full length.

- Run a short empty cycle and check for leaks at both ends of the hose.
- Make sure water drains smoothly without backing up.
