4. Configuración e instalación

This section provides general guidance for replacing a water inlet valve. For detailed, model-specific instructions, refer to the service manual for your particular LG Washing Machine model.

1. Preparación:
   • Disconnect the washing machine from the electrical power supply.
   • Turn off the hot and cold water supply to the washing machine.
   • Move the washing machine away from the wall to access the rear panel.
   • Place towels on the floor to catch any residual water.
2. Acceder a la válvula:
   • Remove the rear access panel of the washing machine, typically secured by screws.
   • Locate the existing water inlet valve assembly. It will have water hoses connected to it and electrical wiring.
3. Desconecte la válvula vieja:
   • Carefully disconnect the hot and cold water inlet hoses from the old valve. Be prepared for some water spillage.
   • Disconnect the electrical wiring harness from the valve. Note the position of each wire if not clearly marked.
   • Unscrew or unclip the old valve from its mounting bracket or the washing machine chassis.
4. Instalar nueva válvula:
   • Position the new LG AJU75152601 Water Inlet Valve Assembly in the same location as the old one.
   • Secure the new valve to its mounting bracket or chassis using the original screws or clips.
   • Reconnect the electrical wiring harness to the new valve. Ensure connections are secure.
   • Reconnect the hot and cold water inlet hoses to the corresponding ports on the new valve. Hand-tighten, then use a wrench for an additional quarter turn, being careful not to overtighten.
5. Comprobaciones finales:
   • Replace the rear access panel of the washing machine.
   • Turn on the hot and cold water supply. Check for any leaks around the valve and hose connections. Tighten if necessary.
   • Vuelva a enchufar la lavadora a la toma eléctrica o encienda el disyuntor.
   • Run a short test cycle (e.g., rinse and spin) to confirm proper operation and check for leaks under pressure.

5. Principio de funcionamiento

The LG AJU75152601 Water Inlet Valve Assembly functions as an electrically controlled switch for water flow. When the washing machine's control board sends an electrical signal to the valve's solenoids, the solenoids activate, opening internal diaphragms. This allows water from your home's supply lines to enter the washing machine tub. The valve typically has multiple solenoids to control hot and cold water independently, allowing the machine to mix water to the desired temperature for different wash cycles. When the required water level is reached or the cycle changes, the electrical signal is removed, and the solenoids close, stopping the water flow.

6. Mantenimiento

The water inlet valve assembly is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure its continued proper function:

• Compruebe si hay fugas: Periodically inspect the water inlet hoses and valve connections for any signs of leaks or drips. Tighten connections if necessary.
• Inspeccionar las rejillas de entrada: Most water inlet valves have small screens at the hose connections to filter out sediment. If water flow is reduced, these screens may be clogged and require cleaning. Turn off water, disconnect hoses, remove and clean screens, then reassemble.
• Evite apretar demasiado: When connecting hoses, avoid overtightening, as this can damage the valve's plastic threads or rubber washers.

7. Solución de problemas

If your washing machine exhibits water-related issues after installing or while using the LG AJU75152601 Water Inlet Valve Assembly, consider the following:

• No Water Entering Tub:
  • Ensure water supply faucets are fully open.
  • Check if the washing machine is plugged in and receiving power.
  • Inspect the inlet screens for clogs.
  • Verify electrical connections to the valve are secure.
  • The valve itself may be faulty (if all other checks pass).
• Llenado lento de agua:
  • Verifique la presión del suministro de agua.
  • Clean clogged inlet screens.
  • Ensure hoses are not kinked.
• Continuous Water Fill (Valve Not Shutting Off):
  • This indicates a faulty water inlet valve that is stuck open or has a damaged diaphragm. The valve will need to be replaced.
• Fugas en las conexiones:
  • Ensure hoses are properly seated and tightened.
  • Check rubber washers in the hose connections for damage or improper seating.

If troubleshooting steps do not resolve the issue, it may indicate a more complex problem with the washing machine's control system or another component. Consult a qualified technician.
