How do i adjust gran throw on a simonelli grinder

First, I'm not a Simonelli technician. Though I've worked on similar table top machines.
* The grinder on these small machines (compared to commercial units) are usually manually adjusted. They are usually built with a range from very fine Turkish coffee (like talcum powder) to a fairly fine auto drip grind. You should not be able to coarse it up as used in a french press.
* There should be some sort of indexing to indicate at least the direction to rotate the grind adjust, say; fine to coarse, or even Turkish to American, etc. Though it may be a generic + to -.
* There may be a positive 'click' to each setting or possible hold down lock mechanism. But the most common is a spring loaded nub that clicks into place. If yours did click before and not now then you need to take it in for service as you probably lost the part (tiny ball and spring)
* A thought; If your an "Americano" drinker (course grounds will hot water filtered through it to fill a Mug size cup) then it may have happened when adjusting to the larger grind size. The indexer ball and spring is only held down by the height of the grind ring. Exceeding the largest grind will allow the ball and spring to pop out of position which can fall into the burrs and destroy them. It may be possible the ball (steel ball bearing) is still trapped in the burr plates and moves them around. Can't grind steel.
* Still got problems? Check with vendor or MFR for service or replacement. Most machines of this type do not have serviceable parts or adjustments.

THE POWER SWITCH MAYBE DAMAGED

make your grinder more fine
the coffee is gross

change the clump crusher or maybe it is missing

Remove the bean hopper and vac out all beans, then remove black cover, then 3 phillips screws, and top part of burrs should come off. Clean our chamber then reassemble. DO NOT TURN ON. Make sure middle nut in chamber spins freely, use fingers to turn, if not adjust setting to coarser, until it moves freely, then turn on grinder. All you have to do now is set your grind.

On the adjusting knob there are 2 set screws (outside of the center) and an adjustment screw (the one in the middle). First make sure the LARGE screws on the side of the SELECTOR plate are tight. Start with the selector on Turkish, with the grinder OFF loosen the set screws about one full turn each. Leaving the selector on Turkish turn the grinder on and gradually VERY SLOWLY turn the center screw clockwise. Eventually you will hear the burrs inside touching. After they touch back of the center screw about 1/8 of a turn. Tighten the SET SCREWS tight as they may allow the grinder to go out of adjustment if not tight. Test the grind with very little coffee and throw those grounds out. Then grind and brew! If these grinders are adjusted too fine you may have problems with the grinds not falling and may back up.

There isn't one, because your grind depends on the bean you are using, the temperature and so on. The best thing you can do is clear the burr chamber of beans, then turn grinder clockwise until you can no longer turn the brass fitting in the middle, then turn counter-clockwise to about 4 numbers that will give you a nice starting point to setting your grind.
