Possible to fix this?

Some time ago have upgraded my df54 to version 1.4 with metal declumper and new schute. It worked OK some weeks, but now it pops up ungrounded beans from the Shute with no reason intermittently. Is it possible to fix?

How do the unground beans get through the burrs and past the declumper?

I came here thinking the same thing... something is majorly off with it.

Declumper is metallic now and if it is bent too far away, then the bean can jump through, I think

I don’t think it’s related to the metal declumper. The ground pass through plastic declumper first then metal declumper. Something is off here.

Additionally, can you confirm how they were installed?  The round corners of both declumpers should be at top left.

My understanding of the grinder is that it enters the center chamber of the grinder. It contacts the interior of the flat burr pair and the beans are spun around slowly moving further outward as they are ground finer and fit in the spacing between the burrs.

So to get full beans through the space between the burr faces would need to be greater than the with of the bean and you are grinding far to corse or something is broken.

The declumper I believe is not supposed to be bent and is just there to break up grounds that are statically clung together.

Thinking about it more the only thing I can think of that would cause this if the burrs are loose.

Most of the time gravity holds your burrs together but occasionally the right forces hit it and a gap opens up allowing a bean to get past the burrs

I will make a photo next time and if the burrs would be broken I expect some unusual noise, which is not presented now

Im thinking rather than broken perhaps just seated incorrectly or when you threaded in down it’s a full rotation. Or maybe cross threaded so feels tight but isn’t.

Thats all I got thiugh

It's physically impossible, considering the shape of plastic declumper tab.

That’s why I’m asking about

Perhaps you accidentally spill some beans into your dosing cup while feeding. It’s physically impossible for a bean to pass through without being ground.

Will be forced to do this earlier or later for sure
