Disable the LG washer/dryer melody at end of the cycle?

Question

Title is the question, the loud melody is obnoxious. This is a last ditch effort, the manual doesn't provide any information, surprisingly this fairly comprehensive machine doesn't seem to be designed to disable a sound? Is there a cord to cut or sequence of steps to silence the sound?

Model: LG WM3997HWA Ventless 4.3 Cu. Ft. Capacity Steam Washer/Dryer Combination with TurboWash, TrueBalance Anti-Vibration System, NeveRust Stainless Steel Drum, Allergiene Cycle in White

Answer 1

I've used the following method to make obnoxious sounds coming from home appliances and toys much quieter:

1. Find where the sound comes from. Usually there's a little grill or perforated plastic that covers the loudspeaker or piezo inducer.
2. Tape over it with a transparent office tape. I sometimes do two layers in cross-hatch pattern if sounds are very loud.

Usually, it makes the sound quiet enough not to be bothersome anymore. You could, of course, disassemble the whole thing and cut the wires to the speaker (if it's not PCB-mounted, which many of them are), but in my experience just covering the hole where sounds come from is good enough.

Answer 2

Manufacture mentioned there is no way to silence sound.

Inspired by Haimg's advice, I disconnected one of pins from the speaker module off of the components board.

Answer 3

Strangely, page 26 of the manual mentioned in the question says the following:

Does that not work, or only apply to some subset of this model? Maybe there is some trick to get it right (sometimes these translated messages lack certain clarity). I would guess that it probably resets if power is lost.

I would not recommend physically cutting any wire to silence the beast. Sounds are also used by the repair technicians to diagnose problems. (if repair is ever needed)

Answer 4

I thought my washing machine couldn't be silenced, but the manual section titled "Signal" advised to hold down the Extra Rinse button for 3 seconds to control the volume.
