Whirlpool Duet Sport Pump?

The fact hat it pumps the water out quietly but makes a noise when it is spinning makes A bearing ot flange suspect. Right?

It would.

But, the tempo does not change. That is throwing me off.

Odd!

Now that I am at work I listened again to the video....still sounds like just the pump sucking in air when there is no more water to pump.....which is normal.
There might be a -slight- louder bearing noise but seemed like nothing terrible.

pump sucking in air

That might explain making a sound when it is spinning with no water in it and no change in tempo. I kind of feel like the pump has a small amount of damage and is making a sound when empty that can be picked up with the stehoscope kinda like a grinding sound which transferrs to the back maybe through a recirculation hose. I think we are on to something here. I just can't remember ever hearing one do this. This makes me think the pump has some damage.

Right now, this thing works like a charm, just has that sound in it.

Thanks.
