Leaking washing machine hoses is more than just a nuisance—water leakage can lead to thousands of dollars in water damage to your floors and home. Left unaddressed, leaking hoses can even create hazardous electrical situations. Replacing old, worn-out hoses is a fairly straightforward do-it-yourself project that can prevent extensive property damage and make laundry day less stressful. This step-by-step guide walks you through the process of identifying leaks, choosing replacement hoses, and installing new hoses properly. With a little time and effort, you can stop leaks in their tracks and do your part to keep appliances running smoothly.

Understanding Washing Machine Hose Leaks

Washing machine hoses connect the hot and cold water supply to the inlet valves on the appliance. There are two primary types of washing machine hoses:

  • Rubber hoses – The traditional style, made of rubber with fiber reinforcements. Prone to bulges and bursts over time.
  • Stainless steel braided hoses – The newer, more durable style with a stainless steel outer layer and rubber inner hose. Recommended for replacement.

Hoses typically leak from the ends where they connect to the washer or faucet, or they burst in the middle from a weak spot that bulges out. Common causes of leaks include:

  • Age – Hoses older than 5 years can become cracked and porous.
  • Wear and tear – Fraying from twisting and pulling can create splits and cracks.
  • Corrosion – Brass and rubber connections corrode over time.
  • Improper installation – Leaks often occur at connection points if attachments are not secure.

Signs of a hose leak include:

  • Water pooling around the washer
  • Visible water spray from the hoses
  • An unusually high water bill

Catching and replacing leaking hoses early is critical to preventing extensive water damage.

Preparing for Hose Replacement

Replacing washing machine hoses is a straightforward project that most DIYers can tackle. However, it does require turning off the water supply lines and power to the washer. To minimize downtime, make sure to assemble all necessary tools and parts before disconnecting anything.

Tools/Materials Needed

  • Adjustable wrenches (two)
  • Replacement washing machine hoses (two)
  • Teflon tape
  • Bucket
  • Towels
  • Flashlight
  • Pliers

Choosing New Hoses

When selecting replacement hoses, stainless steel braided hoses are the optimal choice for durability and strength. Make sure any hoses you purchase meet these standards:

  • High-pressure hose with minimum 3000 psi rating
  • Burst rating 5 times the operating pressure
  • Meet ANSI/ASME standards

The new hoses should match the inlet connection size of your washing machine (usually 3/4” or 1/2”). Measure existing hoses and purchase the same size. Also, measure the space between connection points and cut recoil hoses to size if necessary.

Safety Precautions

As with any repair that involves water and electricity, exercise caution:

  • Turn off water supply valves
  • Unplug washing machine
  • Turn off the power at the circuit breaker
  • Verify power is off with a voltage tester
  • Adjust water lines to drain
  • Place bucket under hose connections
  • Check for leaks before restoring power

Taking these preventative measures greatly reduces electrical and water damage risks while replacing hoses.

Step 1: Locate Leaks

Before disconnecting anything, inspect all water connections for visible leaks. Look for:

  • Water droplets forming on brass connections
  • Signs of corrosion around joints
  • Split or bulging hoses
  • Water dripping from small cracks

Also, feel along the hoses, as leaks often weep slowly without visible spray. Any damp or wet spots likely indicate holes and cracks. Thoroughly inspect the full length of both hot and cold water hoses.

If leaks occur at the faucet connections, you may need to replace washers before installing new hoses. For simplicity, this guide focuses on replacing leaking hoses themselves.

Step 2: Disconnect Power and Water

Once you locate all leaks, fully power down the washer before disconnecting anything.

  1. Unplug the machine from the wall outlet
  2. Turn off the hot and cold water supply valves
  3. Open the machine lid to release the pressure
  4. Disconnect inlet hoses from the faucet end
  5. Point hoses into the bucket and drain any remaining water
  6. Disconnect leaking hoses from the washer inlet

With no power running to the machine and residual water drained, you can now safely remove old hoses without leaks or electrical risks.

Step 3: Remove Old Hoses

Taking off old washing machine hoses requires unscrewing them from faucet connectors and inlet valves using pliers and adjustable wrenches. Here are step-by-step instructions:

Faucet End Removal

  1. Place adjustable wrench over connector at faucet end. Grip tightly.
  2. Twist the hose counterclockwise with pliers until fully disconnected.
  3. Repeat steps on both hot and cold hoses.

Washer Inlet Removal

  1. Locate inlet valve connectors at the back of the machine.
  2. Position one wrench to hold the valve end stable.
  3. Use a second wrench to twist the hose counterclockwise.
  4. Remove washers if still in place.
  5. Repeat hose removal on both hot and cold supplies.

In most cases, old rubber hoses can simply be removed completely once disconnected at both ends. If you need to measure new hose lengths accurately, just pull old ones out to reuse them temporarily as sizing guides.

Step 4: Secure New Hose Connections

With the old hoses fully removed, preventative maintenance steps should be taken at all connector points before installing the new set.

Update Faucet Connectors

Examine faucet connectors for any signs of wear, rust, or hard water deposits. Replacing washers and o-rings ensures a tight seal when attaching replacement hoses:

  1. Remove the old washer and o-ring from the hot side faucet
  2. Install updated thicker washer and o-ring
  3. Repeat cold water faucet inspection
  4. Replace any worn washers and o-rings

Washer and o-ring replacement typically costs just a few dollars but prevents leaks down the road.

Clean Machine Inlet Valves

Check washing machine water inlet valves for any dirt buildup or corrosion:

  1. Wipe down inlet valve fittings with rag
  2. Use a steel brush to remove mineral deposits
  3. Ensure surfaces are clean and secure

Taking time to clean connectors allows new hoses to seal completely, preventing leaks from the start.

Step 5: Attach New Hoses

With all connectors prepped, you can install the new washing machine hoses. Follow these guidelines for optimal, leak-free connections:

Faucet Side Install

  1. Wrap male faucet threads with 2-3 layers of Teflon tape.
  2. Hand tighten hose end fitting 3-4 rotations.
  3. Finish tightening the fitting with a wrench until snug.
  4. Repeat hose connections for hot and cold faucets.

Back of Washer Connections

  1. Ensure inlet valve fittings are tight.
  2. Hand thread hose end connections until resistance is felt.
  3. Use the wrench for an additional 2/3 turn until the hand is tight.
  4. Repeat hose attachment for both inlet valves.

Do not overtighten connections. Snug is sufficient to prevent leaks without risking cracks.

Hose Length Adjustments

For recoil-style stainless steel replacement hoses:

  1. Extend the hose to measure the needed overall length
  2. Identify length markings on the hose exterior
  3. Cut at the appropriate date marking the location for a custom fit
  4. File down any sharp edges on the cut end

Proper hose length helps avoid kinks and tension that lead to cracks over time.

With all ends securely fastened, the final step is confirming everything remains leak-free.

Step 6: Confirm No Leaks

Before using the washing machine, verify connections did not loosen during handling:

  1. Slowly turn the water supply back on
  2. Thoroughly inspect joints for any water droplets
  3. Look and feel along hose barrels for damp spots
  4. Check inlet valves and fittings with a flashlight
  5. Observe all connections for 2-3 minutes

If any leaks occur:

  • Immediately turn off the water supply
  • Wipe and dry the connection
  • Retighten the joint slightly
  • Repeat checks

With no leaks present, restoring power and running a test cycle provides final validation. Just be prepared to turn off the machine if new water spots appear.

Preventing Future Hose Leaks

Replacing worn-out hoses provides time until the next incident, but you can take proactive maintenance steps to maximize their lifetime:

  • Inspect hoses annually – Look for bulges, cracks, leaks, kinks, and corrosion.
  • Replace hoses every 5 years – Mark your calendar to revisit in 2029!
  • Avoid kinks and tension – Position hoses with slack to minimize strain over time.
  • Consider hose tubing – Protecting hoses reduces rubbing and abrasions.
  • Use hose hangers – Elevate hoses to prevent ground contact and bend points.
  • Update washers/o-rings – Lack of compression is a top cause of slow leaks.

Building hose inspection into seasonal home maintenance identifies problems early before catastrophic failures. Investing a few minutes regularly preserves appliances and prevents water damage.
