LG ThinQ Washer Delay Wash Timer Resetting to Zero

Troubleshoot why your LG ThinQ Washer's Delay Wash timer resets. Diagnose power issues, software bugs & connectivity problems in your Canadian home.

Frequently Asked Questions

•What is the average lifespan of the RTC battery in the LG ThinQ Washer?

The average lifespan of the RTC battery is typically 3-5 years. However, this can vary depending on usage and environmental conditions.

•How do I determine if a firmware update is necessary for my LG ThinQ Washer?

The LG ThinQ app will typically notify you when a firmware update is available. You can also manually check for updates within the app's settings menu.

•What are the potential risks of using a non-authorized service technician for repairs?

Using a non-authorized technician can void your warranty and potentially lead to improper repairs, which could damage the washer or create safety hazards.

How It Works:

The LG ThinQ Washer utilizes a microcontroller to manage the 'Delay Wash' function. This function relies on a stable power supply, accurate real-time clock (RTC), and consistent communication between the control board and the ThinQ app (via Wi-Fi). Timer settings are stored in non-volatile memory. Firmware updates are delivered OTA (Over-The-Air). Power consumption varies with cycle phase, peaking during spin and heating cycles. Wi-Fi operates on 2.4 GHz band.

Common Causes:

Power fluctuations or voltage dips affecting the control board, particularly during other appliance operation.
Corrupted firmware or software glitch in the timer module.
Failure of the internal real-time clock (RTC) battery or component.
Wi-Fi connectivity issues causing intermittent communication with the LG ThinQ server, leading to timer reset.
Incompatibility with specific Canadian ISP configurations (Bell Giga Hub, Rogers Ignite) affecting device registration and time synchronization.
Environmental factors such as extreme cold (-30°C to -40°C) affecting component performance.

Symptoms:

The LG ThinQ Washer displays the set 'Delay Wash' timer, but it repeatedly resets to zero before the cycle begins. Observed on the washer's LED display and within the ThinQ mobile application. No error codes are consistently displayed. Intermittent behaviour, more frequent during peak electrical load times (early evening).

Pro Tip:

If experiencing frequent Wi-Fi disconnects, try assigning a static IP address to the washer within your router's configuration (e.g., Bell Giga Hub or Rogers Ignite). This can improve connection stability. Consult your ISP's documentation for instructions.

Critical Safety Precautions:

Never attempt to repair the washer yourself unless you are a qualified appliance technician. Disconnect the washer from the power supply before performing any maintenance. Do not bypass any safety interlocks. Ensure proper grounding to prevent electrical shock. Avoid water spillage near electrical components.

Solution:

1

Check the voltage at the wall outlet using a multimeter to ensure it is within the specified range (120V +/- 10%).
2

Inspect the power cord for any damage or loose connections.
3

Ensure the washer is plugged into a dedicated circuit, avoiding shared circuits with other high-power appliances.
4

Power cycle the washer by disconnecting it from the power outlet for at least 5 minutes. Reconnect and re-establish Wi-Fi connection via the ThinQ app.
5

Check for available firmware updates in the ThinQ app and install them if available. Note the version number before and after.
6

Verify that the washer's time zone setting is correct within the ThinQ app. Compare against Canada Time Zones.
7

If the issue persists, contact an authorized LG service technician for diagnostic testing and component replacement (e.g., RTC battery).

Maintenance Tips:

Monitor the washer's performance and error logs regularly through the ThinQ app.
Schedule firmware updates during off-peak hours to minimize disruption.
Consider using a surge protector or UPS (Uninterruptible Power Supply) to protect the washer from power fluctuations.
Replace the washer's internal RTC battery every 3-5 years (if applicable; consult the service manual).
Before winter, conduct a full diagnostic cycle to preempt cold-related issues. Check water inlet valve for proper operation.
