LG ThinQ App Time Remaining Discrepancy: Troubleshooting... | appliancefaults.com

Technical Background:

The appliance's Main Control Unit (MCU) estimates remaining time based on sensor data (temperature, water level, load weight) and programmed cycle parameters. This data is then transmitted via Wi-Fi to the LG cloud and subsequently to the ThinQ app. Voltage fluctuations can affect the MCU's clock speed and sensor readings, leading to timing inaccuracies.

Symptoms:

US homeowner notices the 'Time Remaining' displayed on the LG ThinQ app differs significantly from what's shown on the appliance's control panel during a wash or dry cycle.

Possible Causes:

Inconsistent cycle programming between appliance and app.
Wi-Fi connectivity issues causing delayed data synchronization.
Firmware bugs in the appliance's control board (MCU).
Power fluctuations interrupting the cycle and affecting time estimation.
Inaccurate sensors (temperature, pressure) leading to incorrect time calculations.

Solution:

1

Verify Wi-Fi connection: Ensure the appliance and your smartphone are connected to the same, stable Wi-Fi network. Test connection speed.
2

Reset the Appliance: Unplug the LG appliance from the outlet for 5 minutes. This performs a soft reset of the control board.
3

Re-register the Appliance: Delete the appliance from the ThinQ app and re-add it, following the app's setup instructions.
4

Check for Updates: Ensure both the ThinQ app and the appliance firmware are updated to the latest versions. Use the app to check for firmware updates. (Settings->Product Settings->Software Update)
5

Monitor Voltage: Using a multimeter, verify the voltage at the outlet while the appliance is running. It should consistently read around 120V AC. Fluctuations can cause timing errors.
6

Run a test cycle with a light load and monitor both the app and the appliance display to see if the discrepancy persists.

Safety Warning:

Always disconnect the appliance from power before performing any diagnostic or repair procedures. High voltage is present in the control panel. Use proper Lock-Out/Tag-Out (LOTO) procedures.

Prevention:

Regularly check for firmware updates for the appliance and app. Ensure a stable Wi-Fi connection. Consider a surge protector to mitigate power fluctuations.

Expert Tip:

Try entering the service mode by pressing and holding the 'Start/Pause' button for 5 seconds, followed by quickly pressing 'Temp' then 'Spin' buttons. This can sometimes reset the control panel's internal clock.

Frequently Asked Questions

•How do I check the appliance's firmware version?

Navigate to the 'Settings' menu on the appliance display (if available) or within the ThinQ app. Look for a 'Software Information' or 'Firmware Version' option.

•What if the voltage at the outlet is fluctuating?

Consider using a dedicated circuit for the appliance or consulting with a qualified electrician to address potential wiring issues.

•The display shows the correct time at the beginning of the cycle, but the discrepancy grows as the cycle progresses. What could be the issue?

This likely points to a faulty sensor or a problem with the MCU's algorithm for calculating remaining time. Consider contacting LG authorized service for diagnostics and repair.
