One more thing to try: force-check indexing by searching for a nonsense word on the home screen; if it says items aren’t indexed yet leave it plugged in until that count reaches zero, since stuck indexing can block new downloads. If that’s clear, deregister and re‑register the Kindle to refresh licenses, then deliver a single book from the series via Download & Transfer to that specific device instead of bulk over Wi‑Fi. After failed attempts, connect by USB and delete the partial book and its matching.sdr folder before trying again.

Hey, that sounds frustrating especially when you're excited about those morning smoothies and trying to keep things quick in your busy routine. I've had a similar issue with a blender before and it turned out to be something simple like a loose part inside. First, try unplugging it and giving the base a gentle shake to see if anything rattles around that shouldn't be there, maybe a stray piece from packaging got stuck. If that doesn't reveal anything, disassemble it completely following the manual and reassemble it carefully, making sure all the gears and seals are aligned properly without forcing anything. Sometimes with new appliances, the parts just need to settle in after shipping. If the noise continues, it might be a manufacturing defect, so reaching out to the seller for a replacement could be your best bet, but definitely try running it empty for a minute or two on low to see if the sound smooths out as it breaks in. Hang in there, hopefully it's an easy fix and you'll be blending away soon.
