Hi there, I definitely understand the reason why you would want to disable the sound for the washer and dryer, I cannot handle random loud sound as well, so I totally agree.
I looked through your user manual here- https://downloadcenter.samsung.com/content/UM/202207/20220701141448786/WF6300B_SimpleUX_UM_DC68-0435... and on page. 41 it states "You can turn the alarm sound on or off. When the alarm is off, the cycle completion melody and the power off beep will not sound. However, the other sounds stay active. • Press Alarm Off to turn the alarm on or off. • Your setting will be kept even after you turn off and then restart the appliance."
For the dryer, per the manual here- https://downloadcenter.samsung.com/content/UM/202202/20220226054504986/20211202_DV6300B_DC68-04299K-... found on page. 51 "You can turn the alarm on or off. When the alarm is off, the melody of cycle completion and the power-off beep will not sound. However, the other sounds stay active. • For the DVE(G)45B6300* model, press and hold Drum Light for 3 seconds. • Your setting will be retained even after you turn off the dryer. You can turn the alarm back on by pressing and holding the same button for 3 seconds."
I hope this information is helpful, and I've included the direct links to our e-manuals for the washer and dryer as mentioned above as further review if needed.
