I understand this to mean, that the beans left in the grinder are not resulting in a "good grind" and the resulting coffee "tastes like......".
All you need do is up-end the grinder gently and allow all the beans to fall out, then place it back down gently.
Get the vacuum cleaner out and suck through from insode the hopper, and then suck through from the grinds outlet.
Or....just use the vacuum cleaner to suck all the beans out without upending the grinder......
Run the grinder and make sure there are no more beans or grinds in there.
If the hopper is greasy, remove and wash in warm soapy water. This will also give you better access for the vacuum cleaner. Do not refit the hopper unless it is well and truly dry.
Refill with new beans and away you go. Reset the adjustment as necessary.
ie, no need to unnecessarily pull things apart and run the risk of not getting them back together properly.
