Fridge Water Filter Issues

Sharing this to help others, it's related to these 2 models of water filters, UltraClarity Pro BORPLFTR50 and BORPLFTR55. But my situation may apply to other water filters that Bosch have replaced with newer versions.

​

I have a 1 year old 36" French door fridge/freezer with water and ice dispenser on the left hand side door, we like this unit.

​

The fridge shipped with the UltraClarity Pro BORPLFTR50 water filter. When I went to replace the filter, Bosch indicated that the BORPLFTR50 had been replaced by the BORPLFTR55. Okay, so trust Bosch, they should know their products.

​

When installed, we got the dreaded sound from the area around the left door, like a whining sound. No amount or gallons of flowing water eliminated the sound.

​

I put back the original BORPLFTR50 and the noise was gone! So I tried 2 more replacement BORPLFTR55 thinking this was a filter issue. Nope, noise every time.

​

Had a service visit 3 days ago and Bosch replaced the water filter inlet assembly thinking that was the issue. Seemed okay at first but after the technician left, the noise was back.

​

I tried something today with Google AI help, I turned the water valve down about half way and the noise went away. After further discussion with Google AI, I now believe the noise issue is due to a difference in the 2 water filters, apparently the design of the replacement BORPLFTR55 does not permit as much flow as the older BORPLFTR50 and has caused a water pressure turbulence issue which results in the noise.

​

For now I've left the water valve half open with the new BORPLFTR55 filter but I'm going to try some non-Ultra Clarity filters that may yield different water pressure/flow dynamics, e.g. Water drop brand.
