How to Replace a Washer Inlet Hose
If your washer leaks while filling or you can see cracking, bulging, or seepage at the supply line, replacing the washer inlet hose is a straightforward fix.
This job is mostly about controlling water, working carefully behind the washer, and making sure the new hose seals cleanly at both ends. Take your time, and do a real leak check before pushing the machine back into place.
Before you start: Match the replacement part to your exact washer before ordering.
Safety first
- Shut off the water before disconnecting the hose.
- Unplug the washer before reaching behind it.
- Expect some water to spill from the old hose and protect the floor first.
- Do not over-tighten hose couplings. A crushed washer or damaged thread can create a worse leak.
- Pull the washer forward carefully so you do not kink the drain hose or strain the power cord.

Step-by-step fix
Step 1: Make sure the inlet hose is really the problem
- Look behind the washer while it is off and inspect the water supply hose running from the shutoff valve to the washer inlet.
- Check for obvious cracking, bulging, rust at the metal ends, dampness around the couplings, or a drip trail down the back of the machine.
- If the leak only happens during fill, dry the area first, then run a short fill and watch the hose ends and the hose body with a flashlight.
- Confirm whether you are replacing the hot hose, the cold hose, or both.
If it works: You have traced the leak or visible damage to the washer inlet hose or one of its end connections.
If it doesn’t: If the water is coming from the inlet valve body, internal tubing, drain hose, pump area, or the standpipe, this is the wrong repair path.
Stop if:
- The shutoff valve itself is leaking from the stem or body.
- The wall connection is corroded enough that it may break when disturbed.
- You cannot safely access the back of the washer without risking a tip or damaging the floor.
Step 2: Shut off the water and set up for a controlled disconnect
- Turn off the hot and cold water shutoff valves at the wall.
- Unplug the washer so it cannot start while you are working behind it.
- Pull the washer forward just enough to reach the hose connections without kinking other lines.
- Place towels on the floor and set a bucket or shallow pan under the hose connection you are removing.
If it works: The water is off, the washer is unplugged, and the area is ready for the small amount of water left in the hose.
If it doesn’t: If a shutoff valve will not close fully, stop and address that first or have the valve repaired before disconnecting the hose.
Stop if:
- A shutoff valve will not turn or continues to pass water heavily after being closed.
- Moving the washer reveals damaged wiring, a crushed drain hose, or severe rust that makes the appliance unsafe to handle.
Step 3: Remove the old washer inlet hose
- Loosen the hose coupling at the washer first, then let the remaining water drain into the bucket.
- Disconnect the other end from the shutoff valve.
- Remove any old rubber washer that stuck to the valve or washer inlet connection.
- Wipe both threaded connections clean so the new hose can seat flat against clean surfaces.
If it works: The old hose is off and both connection points are clean and ready for the replacement.
If it doesn’t: If a coupling is stuck, apply steady pressure with pliers and support the valve so you do not twist the plumbing.
Stop if:
- The valve or washer inlet fitting starts turning with the hose instead of staying fixed.
- The threads are cracked, badly cross-threaded, or too corroded to seal reliably.
Step 4: Install the new hose and start the threads by hand
- Check that the new hose has its sealing washers installed in the ends if the design uses them.
- Connect the hose to the shutoff valve and start the threads by hand so the coupling spins on smoothly.
- Connect the other end to the washer inlet the same way.
- Once both ends are hand-tight, snug them slightly with pliers. Do not crush the fittings or over-tighten.
- Route the hose so it is not sharply bent, twisted, or pinched behind the washer.
If it works: The new hose is installed squarely, both ends are snug, and the hose routing looks natural without strain.
If it doesn’t: If the coupling does not thread on easily by hand, back it off and start again to avoid cross-threading.
Stop if:
- The new hose will not seat flat because the fitting is damaged or out of alignment.
- You find the replacement hose does not match the connection size or length you need.
Step 5: Turn the water back on and check for leaks at rest
- Open the shutoff valve slowly while watching the first connection.
- Then open the other valve if you disconnected both hoses.
- Use a dry finger or paper towel around each coupling to catch even a small seep.
- If you see a drip, shut the valve back off and tighten the leaking connection slightly before testing again.
If it works: Both hose connections stay dry with the water turned back on and the washer still idle.
If it doesn’t: If a connection keeps seeping after a small retightening, remove the hose and check for a missing washer, debris on the sealing surface, or damaged threads.
Stop if:
- Water sprays or runs from the valve, wall plumbing, or washer inlet fitting instead of the hose connection.
- A fitting will not seal because the mating surface is cracked or deformed.
Step 6: Run a fill cycle and confirm the repair holds in real use
- Plug the washer back in.
- Run a short wash or fill cycle and watch the hose while the machine is actively taking in water.
- Check both ends again with a flashlight and feel underneath the couplings for hidden drips.
- After the cycle starts, look at the floor under and behind the washer for fresh water.
- Push the washer back carefully, leaving the hose with a gentle curve instead of a hard bend.
If it works: The washer fills normally, the hose stays dry under pressure, and the floor remains dry after the machine is back in place.
If it doesn’t: If the leak is gone during fill but returns later, inspect the drain hose and standpipe next. If the leak still appears at the supply connection, recheck the hose seating and the condition of the fittings.
Stop if:
- The washer leaks from a different component during the test cycle.
- Pushing the washer back pinches the new hose or causes a connection to start dripping.

FAQ
Should I replace just one washer inlet hose or both?
If one hose failed from age and the other is the same age and type, replacing both is often the safer move. If only one is damaged and the other is still in good condition, you can replace just the bad one.
Do I need thread tape on a washer inlet hose?
Usually no. These hoses normally seal with a rubber washer inside the coupling, not with thread sealant on the threads.
Why is the new hose still leaking at the connection?
The most common causes are a missing or crooked rubber washer, debris on the sealing surface, cross-threading, or a damaged valve or washer inlet fitting. Shut the water off and inspect the connection closely.
How tight should a washer inlet hose be?
Hand-tight first, then a small additional snug with pliers is usually enough. Over-tightening can damage the washer or fitting and cause leaks.
Can I reuse the old rubber washer from the old hose?
It is better to use the new sealing washer that comes with the replacement hose, or a new correct-size washer if needed. Old washers can be flattened or cracked and may not seal well.
