Hey @bab and @billc, thanks a ton for such helpful replies! I merged both your posts into one and assigned it to the system user so that the solution can show up better in the docs: Exhaust fan making a loud noise - Docs - Roast World Community
Very nice. So you have to manually add it to the “docs” option in the menu or will it automatically do that once a thread is tagged as an faq? I also see the “solution” check that’s also nice feature. You might want to make a separate post to tell people about this 
Sure! I’ll write a post tomorrow to let everyone know I think as long as it’s tagged with FAQ it should show up. I’m planning to curate it as more posts are added or if there are more questions that are commonly being asked.
@strausal24opu ,
i’d suggest you remove the fan, clean it up and put it back. make sure you keep the fan exactly in the centre, neither too inside nor to out and than tighten the screw. after that make sure the chaff filter it properly pressed inside the washer.
try that!
Hey all, so I had the loud fan grinding noise, took off the fan centered it, ran it with out the back attached to see if the noise was caused by gasket rubbing, it made the noise, so it seems as if it isn’t the rubbing issue (although there is wear on the impeller, which could cause balance issues) so there may be multiple issues. It seems as if the shaft that the impeller sits on is wobbly? Maybe it’s meant to be a little loose.
Hi @dankern.SZDP,
You’ll need to take off the Impeller and Back Cover (plastic case), remove the Exhaust Fan Motor, and check the Gasket (holding the Exhaust Fan Motor and Squirrel Cage). The 3 screws holding the Gasket and Exhaust Fan Motor are likely loose. Please tighten them, re-install everything, and see if the issue goes away.
Best regards,
Kevin

Any information on how and where to remove the back cover? Thank you so much for your responses!
Take off the chaff collector, and you will have access to 4 screws through the holes in the stainless steel plate. I believe this is described in the manual.
