LG Washer Auto-Dose Leaking into Drum: Diagnostics -... | digitalhomefaults.org

Technical Background:

The LG Auto-Dose system utilizes electronically controlled solenoid valves to dispense detergent and fabric softener from internal reservoirs. These valves are governed by the washer's control board, which responds to user settings and sensor inputs. The dispenser drawer connects to the drum via internal tubing. Failure in any component within this system can lead to unintended fluid discharge. Communication occurs via Wi-Fi (2.4 GHz) to the ThinQ app, displaying system status and error codes. Firmware updates are pushed OTA.

Symptoms:

Water detected inside the washer drum when the appliance is idle. LED error code may indicate a fill valve malfunction. Verify by visually inspecting the drum after the Auto-Dose system is expected to be inactive. Check for error logs in the LG ThinQ app related to water levels or dispenser control.

Possible Causes:

Defective solenoid valve within the Auto-Dose dispenser module.
Cracked or damaged tubing connecting the dispenser to the drum.
Faulty water level sensor providing inaccurate readings to the control board.
Mineral buildup or debris obstructing the solenoid valve's proper closure, exacerbated by hard water common in some Canadian regions.
Control board malfunction causing continuous activation of the solenoid valves.
Air pressure buildup within the dispenser system due to blocked vents or improper venting.

Solution:

1

Disconnect the washer from the power supply (breaker lockout) and water source.
2

Access the Auto-Dose dispenser module. Refer to the LG service manual for your specific model.
3

Visually inspect all tubing for cracks, kinks, or loose connections. Replace damaged tubing.
4

Test the solenoid valves using a multimeter to check for continuity when deactivated. Replace any faulty valves.
5

Inspect the water level sensor and its wiring for damage or corrosion. Calibrate or replace the sensor as needed.
6

Clean the dispenser drawer and internal components with a mild detergent to remove mineral buildup or debris.
7

Reassemble the washer and test the Auto-Dose system. Monitor for leaks and verify proper operation.

Safety Warning:

Ensure the washer is disconnected from the power supply before performing any maintenance or repairs. Water and electricity can create a hazardous environment. Do not attempt to bypass or disable any safety features of the appliance. Secure all data credentials used within the LG ThinQ app and be aware of potential privacy implications when connecting IoT devices to the home network.

Prevention:

- Use only high-quality, low-sudsing detergents recommended for HE washers. - Regularly clean the dispenser drawer and internal components to prevent mineral buildup. - Inspect tubing and connections periodically for signs of wear or damage. - Ensure the water supply lines are properly connected and free of leaks. - Run a washer cleaning cycle with a washer cleaner every 1-3 months, depending on water hardness.

Expert Tip:

Perform a manual dispenser test by activating each solenoid valve individually through the diagnostic mode (consult the LG service manual for access instructions). This isolates each valve and helps pinpoint the source of the leak. Consider replacing all solenoid valves as a preventative measure, especially if one has failed.
