LG ThinQ Washer: Troubleshooting a Stuck Child Lock (CL)... | digitalhomefaults.org

Technical Background:

The LG ThinQ washer uses a software-controlled electronic lock to disable the control panel. The 'CL' function typically disables all inputs except for the power button. This function's state is stored in non-volatile memory. Communication between the control panel microcontroller and the main processor might be interrupted. Firmware issues, sensor malfunction and capacitor degradation may lead to this error.

Symptoms:

The washer displays 'CL' on the control panel, and all buttons are unresponsive except for the power button. The ThinQ app may also indicate the child lock is active despite attempts to disable it remotely. Repeated presses of the control panel buttons yield no change, even after power cycling. LED indicator for the child lock remains illuminated.

Possible Causes:

Firmware Glitch: Temporary software error causing the child lock to remain engaged.
Control Panel Defect: Malfunctioning button or internal circuitry preventing proper signal transmission.
EEPROM Corruption: Corrupted data in the memory storing the child lock status.
Power Surge: A sudden voltage spike damaging the control panel electronics. This is common in older Canadian homes during storms.
User Interface (UI) Board Failure: Faulty UI board preventing the signal from reaching the main control board.
Cold Weather: Extreme cold may impact the responsiveness of the physical button sensor.

Solution:

1

Power Cycle: Turn off the washer by pressing the power button, then unplug it from the wall for at least 5 minutes. This allows for a complete reset of the internal electronics.
2

Button Test: After plugging it back in, try pressing and holding the 'Child Lock' button (or the combination of buttons specified in the user manual) for 3-5 seconds. Verify that the 'CL' indicator disappears. Consult the physical manual if the digital copy is not available.
3

Factory Reset (if available): Some LG washers have a factory reset option. Consult the user manual for specific instructions. This may require a sequence of button presses.
4

ThinQ App Troubleshooting: Log in to the ThinQ app. Navigate to washer settings and attempt to disable the child lock remotely. Ensure the washer is connected to your home Wi-Fi (2.4 GHz network is recommended) and your Bell Giga Hub or Rogers Ignite modem is configured correctly.
5

Check for Firmware Updates: Use the ThinQ app to check for and install any available firmware updates. Outdated firmware can cause unexpected behavior.
6

Physical Inspection: Check the physical button for any signs of damage or debris. Clean the button and surrounding area with a dry cloth.
7

Contact LG Support: If the issue persists, contact LG customer support in Canada or a qualified appliance repair technician for further assistance. Provide the model number and a detailed description of the problem.

Safety Warning:

Disconnect the power supply before attempting any physical troubleshooting. Do not attempt to repair the washer if you are not qualified to do so. Contact a qualified technician. Do not operate the washer if there are any signs of electrical damage. Be aware of the potential for water leakage and take necessary precautions.

Prevention:

- Regular Firmware Updates: Keep the washer's firmware up to date using the ThinQ app. - Surge Protection: Use a surge protector to protect the washer from power surges, especially during thunderstorms. Consider a whole-house surge protector for added protection. - Avoid Overloading: Do not overload the washer, as this can strain the motor and other components. - Proper Ventilation: Ensure the washer has adequate ventilation to prevent overheating. - Scheduled Maintenance: Follow the manufacturer's recommended maintenance schedule.

Expert Tip:

Try pressing the 'Start/Pause' button and the 'Temp' button simultaneously for 5 seconds. This sometimes overrides the child lock function on specific LG models. This is an undocumented feature and may not work on all models. If this doesn't work, consult the user manual or LG support.

Frequently Asked Questions

•What is the default Child Lock combination on my LG ThinQ Washer?

Refer to your specific model's manual, but it is often a combination of two buttons held down simultaneously for 3-5 seconds, such as 'Rinse+' and 'Soil Level'.

•How do I ensure my LG ThinQ Washer stays connected to my Rogers Ignite Wi-Fi?

Ensure your Rogers Ignite gateway is broadcasting a 2.4 GHz network. The LG ThinQ Washer typically requires a 2.4 GHz connection. Position the washer within a reasonable proximity to the router to ensure a stable Wi-Fi signal. Check your Rogers Ignite app for connected devices to verify the washer is online.

•Where can I find the model number of my LG ThinQ Washer?

The model number is typically located on a sticker on the back of the washer, or inside the door frame. It usually starts with 'WM' followed by a series of numbers and letters.
