  • Towel
Safety Guidelines
  • Always disconnect the power supply to the washing machine before starting any repairs. Failure to do so could result in electric shock.
  • Turn off the water supply to the washing machine using the shut-off valves located behind the machine. This prevents water leakage during the repair.
  • Have a bucket or towels ready to catch any remaining water in the inlet hoses. Some water may remain even after turning off the supply.

  1. Prepare for Replacement

    • Turn off power and water supply. Unplug the appliance or switch off the circuit breaker. Turn off hot and cold water supplies.
    • Protect the floor. Place a towel down on the floor to prevent water damage.

Tips

  • Always disconnect power and water before working on any appliance to prevent electrocution and water damage.
  • Label your hoses to avoid connecting them incorrectly. If your shut off valves aren't color-coded, label them clearly.
  • If the hose is difficult to remove, use a small flathead screwdriver to help loosen it.
  • Parts may vary slightly, but the installation process remains largely the same.
  • Remember to use the correct torque for the screws (number 20 in this case).

Common Mistakes to Avoid

1. Incorrect Valve Identification

Reason: Purchasing the wrong water inlet valve for your specific Whirlpool Duet model. Different models use different valves.
Solution: Verify the model number of your washing machine and cross-reference it with the part number on the new valve before purchase.

2. Improper Water Supply Line Connection

Reason: Failing to properly secure the water supply lines to the new valve, leading to leaks.
Solution: Tighten the compression fittings on the water supply lines securely by hand, then use pliers to give them an additional ΒΌ turn to ensure a tight seal.

3. Ignoring Electrical Safety Precautions

Reason: Not disconnecting the washing machine from the power source before beginning repairs, leading to potential electrical shock.
Solution: Always unplug the washing machine from the power outlet and turn off the water supply before starting any repairs.
