I have the Samsung washer WA52J8700A and I've noticed recently that the volume of the notification tune when the cycle is done has gotten really quiet. I see how to turn the volume on/off but that's not the problem. It's turned on, it's just gotten really quiet where you have to be in the same room with it to hear when it goes off. The dryer, you can hear half way across the house and you used to be able to here the washer like that as well. Is there a volume control for this or is something else wrong? Thanks.
