The inner drum, not the tub. i have the same problem, there is water inside the bottom plastic base….why? But i dont think it is supposed to be there….why do those who have answered keep talking about the tub? The question is clearly about the drum.
I have taken my washer apart multiple times in order to clean it because sand and dirt remains in drum after spin cycle.
All is clean, all works fine. But there is water in the drum. I imagine this water is dirty and while spinning the dirt is forced out. I believe the drum should not have water in it, and it should be sealed. Long answer, sorry. I checked prices of drums, almost $500…..not worth buying. I give up. This culture we live in is a replace culture. Why fix it.
