By following this guide you will install a washing machine safely and correctly, covering space preparation, hookups, leveling, and a test run. You’ll learn how to route the drain, connect hot and cold water, ensure a grounded electrical outlet, and verify there are no leaks. Proper installation protects your warranty and reduces repair costs.
Why proper installation matters
Proper installation ensures safety, protects your warranty, reduces the risk of leaks, and helps the machine perform optimally. A correct setup minimizes vibration, prevents water damage, and supports energy efficiency. The Best Washing Machine team emphasizes that taking the time to install correctly pays off in reliability and lower maintenance costs over time. Following local codes and manufacturer guidelines is essential. This foundation sets the stage for a long, trouble-free service life and keeps your home safe. Always unplug the unit before starting, and if you are unsure about any step, consult the user manual or a qualified technician. A solid installation also helps with balancing to avoid noise and movement during cycles.
Preparing the installation space
Before you begin, remove packing materials and set the washer in its final location. Check clearance for the door to swing open fully and ensure there is a dedicated electrical outlet within reach. Level the floor area and remove any loose debris that may cause instability. If you are replacing an old machine, disconnect and safely move it away. Prepare towels and a small bucket to catch any residual water during connections. By planning the space, you reduce the chance of awkward bending, leaks, or damaged walls.
Inlet, outlet, and power basics
A washing machine uses a hot and a cold water inlet, a drain, and a grounded electrical outlet. Modern models typically have standard hoses that thread onto insulated valves. Make sure you have shut off valves accessible and ready. The drain must connect to a drain receptacle or standpipe, and the power source should be grounded and on a GFCI protected circuit when required by local code. Read the manual for model-specific requirements and hose types. This clarity helps prevent cross threading and leaks that can be costly to repair.
Connecting the water supply
Attach the hot and cold water hoses to the corresponding valve connections on the washer and tighten by hand, then snug with a wrench. Do not over tighten as this can damage the hose fittings. Check that washers inside the hose connectors are seated properly to prevent leaks. Turn on the supply valves slowly and watch for drips. If you see leaks, shut off the valves and re-tighten. Keep the hoses above floor level to prevent backflow and potential contamination.
Drain hose routing and securing
Install the drain hose into the designated opening or standpipe following the manufacturers recommendation. Do not kink or crush the hose. Secure the drain hose using a clip or retainer to avoid it slipping out during a cycle. If your model uses a standpipe, ensure it is at a safe height and that the hose reaches without tension. A poorly routed drain can cause siphoning or overflow, so be thorough in this step.
Electrical safety and outlet considerations
Avoid using an extension cord. Use a properly grounded outlet that matches the washer's power requirements. If your home lacks a suitable outlet, have an electrician install one. The presence of a GFCI outlet improves safety around water and reduces shock risk. Ensure the cord is not stretched or placed under the machine where it can be pinched. Always unplug before performing any adjustments after plugging in.
Leveling and stabilizing the washer
Place a level on the top surface and adjust the leveling feet until the unit sits evenly with no side to side tilt. Lock the feet in place and re-check the level from front to back and side to side. An out of level machine can cause excessive vibration, moving hoses, and poor performance. If you hear thumping during cycles, readjust the feet and test again after a short run. Keep the area dry and clean around the feet to prevent rust and corrosion.
Common pitfalls and how to avoid them
Never mix connections or cross thread hoses. Do not skip checking for leaks during the initial test run. Do not ignore clearance and door swing requirements or the need for a level surface. Avoid using damaged hoses or old fittings. Do not rely on a power strip; use a dedicated outlet. Finally, review the warranty terms and registration steps to ensure your installation remains protected.
Post install testing and maintenance
Run a short cycle with an empty drum to verify proper water intake and draining. Observe all connections for moisture and listen for unusual sounds. After testing, clean up any mess and store tools for the next time. Schedule occasional checks for hose wear or wall clearance to catch issues before they cause damage. Keeping notes of model specifics helps with future servicing and resale value.

Steps
Estimated time: 60-90 minutes
- 1
Unpack and inspect the washer
Carefully remove packing materials and inspect the unit for any shipping damage. Check hoses and connectors for kinks or defects. This step reduces surprises during installation and preserves warranty coverage.
Tip: Take photos of any damage and consult the seller if found. - 2
Move washer into final position
With assistance, slide the washer into its location using a dolly or careful lifting technique. Leave space for hoses, the door, and access to the electrical outlet. Avoid pulling cords through tight spaces.
Tip: Keep the path clear and avoid twisting hoses while positioning. - 3
Connect the water hoses
Attach the hot and cold hoses to the corresponding valves on the washer and tighten by hand before using a wrench to snug. Ensure gaskets sit properly to prevent leaks. Slowly open the valves and observe for leaks.
Tip: Do not over tighten; cross-threading can cause leaks that are hard to fix. - 4
Secure the drain hose
Route the drain hose into the standpipe or drain opening as recommended by the manufacturer. Avoid kinks and secure with a clip or strap to prevent movement during cycles.
Tip: Never push the drain hose into the drain deeper than necessary; secure height per manual. - 5
Connect power and test the outlet
Plug the washer into a grounded 120V outlet. If your outlet test indicates an issue, consult an electrician before powering on. Do not use an extension cord or power strip.
Tip: If the outlet trips a breaker, stop and recheck connections instead of forcing power. - 6
Level the washer
Place a level on the top surface and adjust the feet until level in all directions. Re-check after a light test run since vibrations can shift the unit slightly.
Tip: Only loosen feet enough to adjust; overtightening can make leveling difficult. - 7
Run a test cycle
Run a short wash with an empty drum to verify water intake, drain, and spin. Look for leaks at hoses and fittings and listen for unusual noises.
Tip: Stop the cycle immediately if you notice leaks and tighten connections. - 8
Final checks and cleanup
Inspect all connections one last time, wipe any moisture, and store tools. Note model specifics for future maintenance and warranty documentation.
Tip: Keep the user manual in a handy place for future reference. - 9
Document setup and maintenance plan
Create a quick reference of your model, required maintenance intervals, and a photo log of the installed setup. This helps with future service and resale value.
Tip: Schedule periodic hose inspections every 1–2 years.
