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?

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