Hey everyone,

I'm hoping someone here has run into this before . My Philips 3300 recently started making this super loud, high-pitched squealing/whining noise. You can hear it perfectly in the video around the 6-10 second mark.

I figured it was just needed for some lubrication, so I did a deep clean. I pulled out the brew group, washed away all the old coffee grounds, and put some silicone grease. I lubed the big orange O-ring, greased the side rails and the inside of the main cylinder.

...But it’s STILL making the exact same noise!

Has anyone dealt with this specific sound before? Is there some secret hidden spot I forgot to lube?

Any advice would be amazing.

Thanks!
