So, our drain pump stopped working after washing some bloody disintegrating rug, and everything was cloaked with some kind of sand.
The drain pump was failing but we could still hear the motor running.
We took apart the machine, and the drain pump. Now, the drain pump-motor combination has the typical impeller, and the coils are well separated from the turning part.
When opening the motor housing, we noticed sand and water inside the housing. Is that normal, or a problem?
We watched another video where somebody is taking apart such housing, and in his case as well, there is water and residue inside the housing.
Thanks for insights!
