LG Washer Distorted or Crackly Finish Chime Sound

Troubleshoot a distorted finish chime on your LG washer in Canada. Diagnose speaker issues, firmware glitches, and power problems. Expert repair tips.

Frequently Asked Questions

•What is the replacement part number for the speaker in my LG washer?

The speaker part number varies depending on the specific model. Consult the LG service manual for your washer or contact an authorized LG parts dealer. Provide your model number for accurate identification.

•How do I access the LG washer's service menu to check for error codes?

Accessing the service menu varies by model. Consult the service manual. Some models may require pressing and holding a combination of buttons for several seconds (e.g., 'Start' + 'Temp' simultaneously).

•Is it safe to use contact cleaner on the electrical connections inside the washer?

Yes, use a specialized electronic contact cleaner that is safe for use on plastics and electrical components. Ensure the washer is completely disconnected from the power supply before applying the cleaner. Allow the cleaner to dry completely before reconnecting the power.

Technical Recommendation:

Try gently tapping the speaker housing while the chime is playing. If the distortion changes or disappears temporarily, this strongly suggests a loose connection or a failing speaker.

Observed Symptoms:

The LG washer's 'Finish' chime exhibits audio distortion, crackling, or a choppy sound. The chime may be quieter than usual or intermittently fail to play. The error log in the LG ThinQ app may not show specific errors related to the chime, but general connectivity issues could be present. LED display brightness may be normal.

Technical Background:

The finish chime is generated by a small speaker driven by a dedicated audio amplifier circuit on the main control board. The amplifier receives a digital signal from the central processing unit (CPU) containing the chime data. This signal is converted to an analog audio signal and amplified to drive the speaker. Power fluctuations, component degradation, or firmware corruption can affect this process. Wi-Fi connectivity is not directly related to the chime function, but firmware updates impacting the audio driver could be a factor.

Important Warnings:

Disconnect the power supply to the washer before performing any maintenance or repairs. High voltage AC (120V in Canada) can be lethal. Do not attempt to repair electronic components unless you are a qualified technician. Incorrect repairs can create a fire hazard or electrical shock risk. Secure all wiring and connections after completing any repairs.

Common Causes:

Speaker damage: Physical damage to the speaker cone or voice coil can cause distortion.
Amplifier failure: Degradation of the audio amplifier components can lead to a weak or distorted signal.
Power supply issues: Fluctuations in the power supply to the audio amplifier can cause instability.
Firmware corruption: A corrupted firmware update may affect the audio driver and cause distortion.
Loose wiring: A loose connection between the control board and the speaker could introduce noise.
Environmental factors: High humidity common in Canadian laundry rooms can corrode speaker connections.

Step-by-Step Fix:

1

Power cycle the washer: Unplug the washer from the power outlet for 5 minutes, then plug it back in.
2

Inspect the speaker: Visually inspect the speaker for any signs of physical damage or corrosion. Replace if damaged.
3

Check the speaker wiring: Ensure the wiring harness connecting the speaker to the control board is securely connected and free from corrosion. Use contact cleaner if necessary.
4

Re-flash the firmware (if possible): If the LG ThinQ app allows, attempt to re-install the latest firmware. Rogers Ignite or Bell Giga Hub may require a temporary network change to 2.4GHz.
5

Check power supply voltage: Use a multimeter to measure the voltage supplied to the audio amplifier circuit on the control board. Compare to the service manual specifications (ensure breaker lockout).
6

Replace the control board: If the above steps do not resolve the issue, the control board may need to be replaced.
7

Contact LG authorized service: For warranty repairs or if unsure, contact LG customer support or an authorized service technician.

Preventative Care:

Regularly check and update the washer's firmware via the LG ThinQ app (OTA updates).
Ensure the washer is plugged into a surge protector to protect against power fluctuations common during Canadian thunderstorms.
Periodically inspect wiring connections for corrosion, especially in humid environments.
Avoid overloading the washer, as this can strain the electrical system.
