Question about Gaggia MDF Coffee Grinder

1 Answer

Grinder is slipping.

While grinding some coffee suddenly my grinder statred to make a noise like it was jammed. I immeadiatly syopped the machine, shook it ant tried again for just a few seconds, same problem. I took the machine apart to clean it out and found a small coffee bean sized pebble. Now after cleaning and reassembly the bottom plate is slipping. I have not taken the grinder appart to see if something is stripped under the brass plate that the holds the burr. My question is can this be fixed? Could about ten seconds of trying to grind a pebble ruin my grinder.

I am pretty handy and would like to do this myself.

    Sorry: I This is a Gaggia MDF. The grinder is 4 years old and is used about four days a week. I am about to try to get the nut that holds the bottom brass plate/burr assembly off. I think the problem lies underneath. I wish there was a schematic I could see to get a picture of how it goes together before I take it apart.

  1. take out bean container
  2. disassemble 3 philips screws and take plastic out
  3. rotate the knob to try to get out the upper holder of burr. if it does not rotate than disasemble the knob and the gears(plastic big one is attached to upper holder of grinder, the other is together with knob.
  4. tru to rotate it manualy, with help of extra srews puted in gear holder holes.
  5. when you get it out, carefuly clean it, look for metal parts and stones(wich sometime comes with coffee)
  1. turn on the grinder and attach gently one marker to lower burr during spining. after you stop grinder, look if it is perfect circle marked in burr. if it is not than marked side is higher. you should consider getting it ok by putting adhesive paper under lower burr and check it again.
good luck and carefuly.

Can't get the grinder grind adjust to turn.

Chances are something is caught on the inside feed to the grinder. Try turning the machine upside down over the sink and turning the switch left and right at the same time. Whatever is causing the jam is likely to fall out.

My Barista Burr Coffee Grinder suddenly grinds too fine.

If it is any consolation, mine just did the same thing, now takes too long to grind and it is way to fine dispite a thorough cleaning by disassembly.

My Bunn Grinder sounds like it is jammed. I have power but no mov

First turn grinder to coarse setting and try grinding some white rice through it, that will clean out the coffee oils, if that does not work then the you will have to open the grinder and clean out the burr chamber and the spout for the grounds.

Rancilio grinder does not grind fine enough for espresso

After taking the top burr off several times and rescrewing it, I finally was able to exert enough force to get it to turn a couple of extra turns. Evidently there was some oil or coffee gunk (although I could see none) that snagged the bur. Now it appears to work as before.

This is a great, service by the way. Even the process of thinking through the problem so I could post it helped me solve it.

Cuisinart burr grind and brew coffee maker

The hopper between the burr grinder and where coffee chutes into the filter is jammed with coffee powder...

First, take out the filter holder and carafe, and place a freash empty filter on the pot base to catch stuff.

Next, take out the beans holder and look for the release lever in the lower left section. Sliding it to the left slides open the door, where you'll probably find loads of powder. You can poke your finger through to get the majority, then use the cleaning brush to get it really clean.

Thanks what fixed mine! (I notice I have to do this about once every few months.)
