What would cause the machine to grind the beans but not produce any coffee despite the water tank being full?


Your grinder setting might be too fine. Only adjust while the grinder is grinding -- set to a coarser grind. Have you tried the preground coffee dispenser? Again, use coarser ground coffee in case the sieve is getting clogged.

I have a mazzer luigi coffee grinder on which set is the best coffee you get


grinding setting is one simple operation but requires a 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 ginding) 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 grinded coffee that come out from doser 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 doser.
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.

My grinder just stopped grinding... turned it on, heard a "Chunk" sort of sound and it stopped grinding. Timer works and light comes on but no grinding. I also cannot unscrew the top portion to look and...


  • DIAGNOSIS

  • it can be too tight stringed at burrs
  • some stone or metal part with coffee went between burs
  • IF IT IS AUTOMATIC, it can be one of 2 micro-switches or main relay, in this case you have power but only to middle of way.
SOLUTIONS

  1. Release the burrs, grind one amount coffee with bigger granulation than go back again carefully.
  2. Disassemble the upper burr holder and clean carefully, all coffee and remains put in one plate, inspect with magnet, hand and than put all that in water. (heavy parts fell down fast in water)
  3. Check the switches and relay:
  • Upper micro-switch has an plate and one box where it is( box might be full of coffee or the plate blocked and giving the signal of full doser every time)
  • Lower micro-switch should activate every 6th pull of doser(he is below in mechanism of doser)
  • Relay gets power from micro-switches when they command. even we switch on if the commandsof micro-switch says off than relay will not obey us.

Coffee is not strong enough?


Hi
There are 2 knobs in the bean hopper. Turn the small one to the + then back up 1 click. Turn the large knob to a smaller number, but only when it is grinding. The grind should look like coarse granulated sugar. It takes 3 cycles for the grind to take effect.

Hi
Has the size of you ground coffee changed? If it is not the size of granulated sugar then its your grinder. Check ebay completed listings. Saw one there couple weeks ago.

What does the coffee produced taste like, is it bitter and watery, is there any creama on the espresso shot. Try adjusting the grind and the coffee level, maybe a little coarser.
