I bought an ecobubble washing machine recently and it's started to make this buzzing sound. I suspect it's when the machine is supposed to be making the bubbles? The machine doesn't get too bubbly anymore.
Should I contact Samsung over this? I've attached a YouTube link that I recorded. Thank you.
I have the same issue with my WW81J5426DW.
This noise seems coming from the bubble pump. This occurs sometimes when the bubble pump starts (I don't know why). After some seconds, the noise disappears as you can see in my video. https://www.youtube.com/watch?v=z6cjfxxQQE0
You can reproduce this issue more often with the "eco" cycle because this cycle uses the bubbles during all the cycle. For other cycles this occurs at the beginning of the cycle when the machine produces bubbles to get foam.
If the noise occurs and you press the pause button, then continue the cycle, the noise disappears.
My wash machine is quite new (bought in August 2020). I checked the filter, it was clean and the propeller of the pump seems not blocked.
I don't know if this noise is really a problem and can cause damage. For now, my machine works fine (except this buzzing noise). For sure this noise seems not normal.
