Humm, G-3 grinders. Okay what common problems I've come across:
* Wrong setting for grind on label. Usually means worn out grinder burrs. But this does not happen often unless you are using it to grind commercial amounts of coffee? It's a retail level grinder meant to be user friendly and simple to use. Say grind a bag of beans once every 10 mins or so even with customers lined up to grind there own. Running a G-3 constantly is usually done by upcoming coffee vendors whom are using it for small flavored bean batches. But expect the burr plates to only last 3 to 6 months. We used to change it every month till the boss bought a bigger pro grinder. (whew!)
* Out of calibration (for grind) This usually happens as soon as it's installed. Either the grinder got banged (Dropped?) around or the lock nut was not tighten down. If caught quickly then it's a simple adjustment. Left unchecked will wear out the burrs or crack the plate.
* Trips out breaker. This is common at retail stores as it's located in a shelf rack that really does not have the required outlets. Many times there is a brewer(s) connected to the same line. It only trips out when one or both brewers are heating and the grinder is running a very fine grind.
* Trips out breaker when grinding espresso or very fine grinds. Worn burrs or slim chance the grinder was miss calibrated (but you would catch this when first installed)
* Shocks the customer. Dry climates or heavy air conditioning will build up static electricity at the chute. There usually a small chain attached to the chute to prevent this. Attach a SHORT metal chain or thin cable to the metal case of the grinder and add a metal clip to attach to the coffee bag. Many use a chain and clip just short enough to keep the bag positioned under the chute. Note many coffee bags come with bag clips. Just make sure the clip and chain can't get stuck in the grinder.
* Not working. This is usually the on/off switch as it gets beat up the most. There is sometimes a safety micro switch under the chute to sense if there is a bag there. I've found may have been defeated.
* No power, check cord, breaker (GFRI) outlet, Plug prongs if broken off or bent.
* power but no motor hum. Tripped thermal breaker (usually a red button on side or back. Some models may have it inside on the motor itself. Call for service to check.
* Turns on but loud hum (may be hot too). Burrs stuck. This could be from adjusting grinder while grinding beans and adjusting to a fine setting. Grinding finer slows down the beans feeding the burrs. Large settings flood the burrs with a lot of beans. Adjustments are usually done when the grinder hopper is completely empty. If loaded and turned down from coarse to fine grind the beans already in the burrs get crushed and stuck between the plates thus locking them in. It may be possible to clear the hopper and open up the grinder to its coarsest setting to jog out the crushed beans. Otherwise call for service to have the burrs cleared manually.
*Finally check with your vendor if your still having problems.

Take it apart again and check all the connections and switches, security shut-offs, and THE THERMAL SWITCH. A very small and cheap electronic device that takes and overload and will shut your system down, whatever it is. Very easy and quick to replace.

The ECM memory should have been rest due to which the calibration of the accelerator pedal has been erased.
Use a scanning tool and calibrate deceleration sensor.
You can do the calibration by clicking Engine and ECT > > special function > > and then click "decleration 0 point calibration" while you do that make sure that your car IGN switch is "ON" and your gear shift is on "P"

If you are asking about the touch calibration
Goto Settings (in the program menu) > Language & Keyboard > Touch Input
Here you can calibrate the touch settings.
If you are asking about Display Calibration
Goto Settings (in the program menu) > Display Settings. Here you can calibrate settings for Animation, Brightness, Screen Timeout etc

Hey

its simple just go to Menu > Settings > Phone Settings > Calibration

you'l be asked to tap on screen until the calibration settings are done.

Thanks.

WERY SIMPLE:

• turn on the grinder
• while it runs you screw upper holder until you hear metal sound of burrs contact
• you go back than for 3 points
• grind 7 grams and test it.

or>>> mark it with marker before disassembling and count the revolutions.

Grinding setting is one simple operation but requires bit patience:

1. Turn on your grinder and continue setting to fine while burrs are spinning, you stop when you hear metal to metal touch sound(burrs maximally closed finest grinding)
2. From that point go back quarter of revolution and mark the spot where you stopped with marker to body of grinder and setting plate with one line
3. Grind little amount of coffee only to fill one sector of dosser than test it at your machine (if it leaks too fast and with yellow color of cream you should go to more fine>><< if it does not leak from the filter holder or it leaks very slow you go to in opposite way.
4. You test grinding few times bit after each reset of plate grind little amount and take that in one other pot (that will provide to have pure new granulation)
5. After setting measure the grounded coffee that comes out from dosser it should be about 7 grams, better measurement you can get if you measure 10 doses in one place because you don't get never same amount from 6 sectors of dosser.

PS: the pump pressure of coffee machine should be from 8 to 10 bar and steam pressure should be from 1.1 to 1.5 bar> depends on type of coffees you use.

Hi
Remove bean hopper
Remove grounds hopper
Remove timer knob on the side
Turn the grinder upside down
There are 4 slits on the outside edge.
Insert a screw driver into the **** and pry gently outward with a
little downward pressure on the outside until the side slips a bit.
Repeat on all 4 slits and the shell should slide off.
There is a fuse on the side of the motor that will blow and stop the motor. It is a thermal fuse and should be replaced by a qualified tech.

1. replacement of burrs after 500 kg grinded coffe
2. if upper burr holder and the body of grinder does not hold stabile, teflon aplying does not help too much, it is only temporary solution. new upper bur holder would do better.
3. before inserting upper burr holder you should check if lower burr is rotating syncronized, you should take a bit chalk and sof touch while burr rotates. after that you stop grinder and look do you have circle with same thiknes, that would give you idea where is the problem, if it is in lower burr.
