4. Installation Guide

This water level sensor switch is a replacement part. Installation should be performed by a qualified technician or an individual with experience in appliance repair. Always ensure the washing machine is unplugged from the power source before beginning installation.

1. **Disconnect Power**: Unplug the washing machine from the electrical outlet.
2. **Access the Sensor**: Locate the existing water level sensor switch within your GALANZ drum washing machine. This may require removing the top panel or other access panels. Refer to your washing machine's specific service manual for exact location.
3. **Remove Old Sensor**: Carefully disconnect the wiring harness and the pressure hose from the old sensor switch. Note the orientation and connection points for reinstallation.
4. **Install New Sensor**: Connect the pressure hose to the new HCDM1734 sensor switch. Ensure a snug fit to prevent leaks or inaccurate readings.
5. **Connect Wiring**: Attach the wiring harness to the terminals on the new sensor switch. Match the connections precisely as they were on the old unit.
6. **Secure Sensor**: Mount the new sensor switch securely in its designated position.
7. **Reassemble**: Reattach any panels or covers that were removed.
8. **Test Functionality**: Plug the washing machine back into the power outlet and perform a test cycle to ensure the new water level sensor switch is functioning correctly.

5. Operation

Once installed, the water level sensor switch operates automatically as part of your washing machine's control system. It detects the water level in the drum and signals the control board to fill or stop filling water as required by the selected wash cycle.

Instructions for Use:

1. Operate the washing machine according to its original instructions provided by the manufacturer.
2. The water level sensor switch will automatically manage water intake based on the selected program.
3. Turn off the power supply to the washing machine promptly after normal use or before any inspection.

6. Maintenance

The HCDM1734 Water Level Sensor Switch is designed for durability and typically requires minimal maintenance. However, to ensure its longevity and accurate performance:

• **Regular Inspection**: Periodically inspect the pressure hose connected to the sensor for kinks, cracks, or blockages. A clear hose (like the one shown in Figure 3) allows for easy visual inspection.
• **Cleanliness**: Ensure the area around the sensor and its hose connection remains clean and free from lint or debris that could affect pressure readings.
• **Avoid Moisture**: While designed for a washing machine environment, avoid direct exposure to excessive moisture or water splashes on the electrical components of the switch during maintenance.

7. Troubleshooting

If you experience issues with your washing machine's water level detection after installing this sensor, refer to the following common problems and solutions:

• **Device fails to start or washing machine doesn't fill**:
  • Check whether the power supply to the washing machine is properly connected.
  • Ensure the water supply to the washing machine is turned on.
  • Verify that the wiring harness to the sensor switch is securely connected.
  • Inspect the pressure hose for any disconnections or blockages.
• **Abnormal functionality (e.g., overfilling, underfilling, incorrect water level)**:
  • Try restarting the washing machine by unplugging it for a few minutes and then plugging it back in.
  • Re-check all connections, especially the pressure hose, for proper sealing and absence of kinks.
  • Ensure the air trap (if applicable to your washing machine model) is clear of debris.
  • If issues persist, consult a qualified technician.

8. User Tips

• When replacing the sensor, take a photo of the original wiring connections before disconnecting to ensure correct reassembly.
• Always use the correct size and type of pressure hose for optimal performance.
• If you are unsure about any step of the installation process, it is recommended to seek professional assistance.
