Grinding Noise - Panasonic NA-140VG3

https://youtu.be/fj8D0YTfnB0

Hello and thank you for this forum. My PANASONIC NA-140VG3 developed a grinding noise about 6 months ago and is getting worse all the time.

It had a new drum and logic board at 5 yrs old under warranty, and now 3 years further at 8 yrs old this issue. It is a very loud grinding noise that occurs when the water is injected into the drum with the side jet on the top right corner of the drum. It does NOT make a noise evacuating the waste water or while spinning. The noise appears to be coming from the pump in bottom left corner, but like I say no noise doing waste water. Drum drive bearings and motor are fine.

I've cleaned the pump from the front tray, cleaned inlet filters and checked the Solenoids. I haven't removed the pump yet to see if any obvious error (not sure how to do that yet) because I'm confused why the pump would be noisy doing one function and not another. Is the pump dual function - ie recirculation and evacuation of the water?

I would very much appreciate some help at this point as I've come to an end of my investigation ability with this issue.

Thank you. AB
