Flipper Max Scraping Sound on Reefer 450

[LittleMaui]

Been using Flipper Max on my 450 for the past four plus years. over the course of the last year it has started making a scraping noise when I clean the glass(see video). Doesn't appear to scratch anything. I replaced the stainless steel blade, but it still makes the noise. Any suggestions or other people having same problem? Can the blade be lubricated to reduce friction?

I watched the video. Now THAT is weird! Has your front glass panel developed a slight bow over time?

 

[LittleMaui]

Nope. Does it on the sides too

Wrote the Flipper folks. Very responsive and helpful! Thinking maybe the small white balls on the inside piece are the culprit. Great Service!

Really? Did they say in what way?
(Good move on your part, by the way.)

They hadn't seen this issue before, but great about responding and helping me troubleshoot. Will try a new inside scrubber piece.
