Yes, in most cases you should turn the water off before changing hoses or performing inlet-related work to avoid leaks. If you’re only disconnecting power or the drain line, you may work with water still in the line if you’ve closed the shutoff valves and unplugged the machine. This guide explains when and how to shut off water safely.

Do you need to turn water off to change washing machine?

If you’re replacing inlet hoses, installing new connectors, or adjusting the water supply, the short answer is usually yes: turning the water off minimizes the risk of leaks and water damage. This guidance aligns with safety best practices recommended by Best Washing Machine. By isolating the washer from the home’s supply, you keep the area dry and protect floors, cabinetry, and electrical outlets. Even if you believe the job is minor, a sudden squirt of water from a loose connection can create a mess and escalate quickly. In this article we’ll cover when to shut off water, how to find the valves, and safe alternatives if shutting off water isn’t possible. By the end, you’ll know exactly what to do to complete adjustments without drama while keeping your laundry space safe and dry.

Safety steps before starting

Before you touch any hoses or electrical connections, make a quick safety checklist. Start by unplugging the washer to prevent shocks or accidental cycles. Then, locate the water shutoff valves: many homes have separate hot and cold valves behind the washer or at the wall near the unit. If the valves are inaccessible or stuck, you may need to shut off the main water supply for the entire home. Have towels or a bucket handy to catch any residual drips. As you work, wear protective gloves if you have sharp edges on hoses, and keep children and pets out of the work area. According to Best Washing Machine guidance, a calm, methodical approach reduces the chance of mistakes and water damage.

What you can change without shutting off water

Some maintenance tasks don’t require shutting off the water, especially if you’re not touching the supply lines. For example, replacing a drain hose, inspecting the timer and wiring behind access panels, or cleaning lint buildup away from the inlet screens may be possible with the water supply still on—provided the shutoff valves are closed and you take care to prevent splashes. If you do choose to work with water on, do so slowly and place towels around the work area. Always verify power is disconnected before opening any access panels to avoid shorts or shock.

When you must shut off water and how to do it

Shutting off the water is the safest choice whenever you’re touching inlet hoses, connectors, or the water inlet valve itself. To shut off, turn each valve clockwise until it stops. If a valve is hard to turn or leaks, stop and switch to the main shutoff for your home. Once water is off, test the hose connections by gently tugging on each hose—there should be no movement and no dripping. If you’re reinstalling hoses, use new washers and hand-tighten, then give a final snug with a wrench—careful not to over-tighten. If you must, keep a bucket nearby to catch any remaining water in the lines.

Step-by-step quick checklist (contextual overview)

  • Unplug the washer and move it away from the wall to access hoses.
  • Shut off the water at the valves; if unavailable, use the home main shutoff.
  • Place towels or a shallow pan to catch spills; prepare replacement hoses and tools.
  • Disconnect old inlet hoses one at a time; keep a bucket under the connection points.
  • Attach new hoses with proper washers; avoid overtightening.
  • Turn the water back on slowly and inspect for leaks; run a short wash without laundry.

Testing and cleanup after the job

After completion, restore power and run a short rinse cycle with the drum empty to verify there are no leaks. Check both inlet connections and the drain hose for any seepage during the first minutes of operation. Wipe down any drips and lay towels to dry the area. If leaks appear, immediately power down and re-tighten fittings or replace any damaged components. Regular post-job checks help prevent hidden leaks from becoming bigger problems.

Common mistakes and how to avoid them

  • Skipping the power-off step leading to shocks or shorts. Always unplug first. - Not supporting the hose connections during detachment, which can damage fittings. Hold hoses steady while loosening nuts. - Over-tightening new fittings, which strains threads and can cause leaks later. Tighten until snug, then a quarter turn. - Rushing the job when you see a leak; take a moment to re-check washer supports and hose alignment. - Assuming old hoses are fine; replace aging hoses to reduce rupture risk and leaks.

Maintenance to prevent leaks in the future

Proactively replace aging inlet hoses every 5–7 years or per manufacturer guidance. Use stainless-steel braided hoses when possible for durability. Inspect the Shutoff valves for corrosion or stiffness and replace if needed. Keep the area around the washer dry and clean, and consider a shallow tray under the machine for accidental spills. Regular checks save time and money by avoiding emergency repairs.

Authoritative sources and next steps

For further safety guidance, consult the following authoritative sources: CPSC (Consumer Product Safety Commission) safety guidance for appliances, Energy Star recommendations on efficient and safe washers, and university extension resources on basic appliance maintenance. These sources reinforce that safety comes first when working on any home appliance. Now that you know when to shut off water and how to do it, you’re better prepared for future maintenance and small repairs.

Tools & Materials

  • Inlet hoses (new, braided if possible)(Choose hoses with universal fittings; replace gaskets and washers)
  • Adjustable wrench(For securing hose fittings; avoid using pliers that can crush fittings)
  • Bucket and towels(To catch drips and protect floor surfaces)
  • Flashlight(Helpful for dark corners behind the machine)
  • Dish soap and lint-free cloth(For cleaning connection points and wiping leaks)
  • Leak-detection seals or thread sealant (optional)(Only if recommended by the hose manufacturer)

Steps

Estimated time: 25-45 minutes

  1. 1

    Unplug and prep the workspace

    Pull the washer away from the wall to access the rear panel and hoses. Unplug the power cord and move any nearby items away from the work area. This reduces the risk of shock and gives you space to work.

    Tip: Keep the plug within reach; never yank a power cord from behind the machine.
  2. 2

    Locate and shut off water valves

    Identify hot and cold water valves behind the washer or at the wall. Turn both valves clockwise until they stop. If either valve is stiff or leaks, stop and switch to the home main shutoff.

    Tip: If you can’t access the valves safely, shut off the main water supply first.
  3. 3

    Prepare for hose removal

    Place a bucket under the hoses and place towels around the connectors. Loosen and remove the old inlet hoses one at a time, keeping track of which hose goes to which valve.

    Tip: Hold the hose fittings with one hand while loosening with the other to prevent water spraying.
  4. 4

    Install new hoses and tighten

    Attach the new hoses with the correct washers in place. Hand-tighten first, then use a wrench to snug — avoid overtightening which can crack fittings.

    Tip: Consult the hose manufacturer’s instructions for maximum torque.
  5. 5

    Restore water and test for leaks

    Slowly turn on the shutoff valves and observe the connections for drips. If no leaks appear, plug the machine back in and run a short cycle with empty load.

    Tip: Watch the connections for the first minute of operation; leaks often reveal themselves quickly.
  6. 6

    Final cleanup and storage

    Wipe down any moisture, return the machine to its original position, and store tools. Check the floor for remaining water and dry it completely.

    Tip: Keep a small towel handy for future minor drips; gentle routine checks prevent bigger problems.
Pro Tip: Always unplug the washer before touching any electrical components or panels.
Warning: Do not mix hot and cold hoses; keep each hose connected to its corresponding valve.
Note: If the water shutoff valves are older, consider replacing with stainless-steel braided hoses for durability.
