Short of throwing it in the bin because in its original state it really is sub standard... Remove bean hopper, top housing, top burr 4 screws in next housing remove it being careful not to lose the button for the safety micro switch. Undo the nut 10mm noting that it is a left hand thread so you need to turn it clockwise to undo it, remove bottom burr and shims and 3 part bearing assy, there is a rubber seal sitting on top of the shaft bearing you need to dig it out carefully without destroying it, you will notice from new these grinders have a lot of lateral movement in this shaft therefore resulting in an uneven grind so what we are doing is replacing this soft rubber seal with something a lot more substantial, what I did was machine up a piece of timber which is all I had but some nylon bush material would be excellent, if machined to a snug finish slid it down the shaft into the plastic housing, then you will have eliminated the shaft movement. Reassemble the bottom burr, bearing, shims, micro switch and housing with the four screws. The next stage is to make up a spacer between the top of this housing and the top section I used masking tape in a spirax effect across the top by sticking multiple overlapping strips until completely covered, then carefully cut out the recesses and around the outside of the housing with a stanley knife this is simply done and very effective. The last stage is to replace the top section, you will also notice that the top burr is also sloppy in the top plastic housing I also fixed this by wrapping masking tape around it until snug, the amount of times you go around will depend on how loose yours is... Thats about it... once you replace the bean hopper etc you will need to back your adjustment off quite a bit, you will find that the "clumping" problem will dissappear and you will have to dial in your grind settings as though it was a different machine.
If you are prepared to make these mods to your em0480 you will find it to be quite a good grinder after all, had sunbeam just taken a bit more care in component moulding, casting and machining they would have produced an awesome grinder, overall it has great features but in its raw state is quite ordinary to say the least.
