Just adding to dhelkamp's instructions (which helped me immensely!).

The front quantity knob kan be pulled right out - it's held in place by friction only.

The side knob has 3 latches holding it in place. Releasing 2 is sufficient. Use 2 small flat screwdrivers.

As for the assembly, there are 4 latches in the inner assembly holding it in place. The location of these latches can be seen by looking at the edge of the outer shell. The front latches are just behind the holes for the rubber feet, and the rear latches are just in front of the rear holes. Use a flat screwdriver to release one of the front latches, while pressing down on the outer shell - it should give way 1-2 mm. Repeat on each of the other 3 latches, whilst keeping pressure on the outer shell. The cover should easily slide off the grinder assembly. Beware of getting pinched!

Given the sophistication of the German engineering behind this product I suspect that the manufacturing in China is not the problem with the switch failure due to material 'fatigue'. This is one of those pesky built in 'fail' designs that causes most consumers to simply go and purchase a replacement grinder.  The plastic tab which is an extension of the switch housing and (secured by a philips screw) fails through plastic fatigue and breaks free of the mount.  It is the most employed 'moving' part in this appliance and could have been much better designed for the consumer.  The design employed suits the stockholder's short term interest. Consumer frustration is well founded.  Conspiracy is just another word for planning!

    My solution was to decide against simply removing the broken switch and gluing reinforcement to the tab plate using a bread bag lock and Superglue.  When that fails I will likely remove the switch,  Good luck!

Remove knob on side (carefully), pry seam on bottom edge of appliance (on underside) using small screw driver at three spots, one on each side, one in rear. Push on clear housing as you do this and entire inner assembly will slide out the bottom, allowing you to remove the black outer cover.

Ya know, the easy thing is to take it apart, then cut the two power cord wires from the timer/interlocks, then cut the timer/interlock wires going to the motor and just wire the motor direct to the power cords. When you plug it in, it runs, when you unplug it, it stops. Just measure your coffee instead of messing with the machine. You can still adjust the grind, which is the important part, and you have a pretty foolproof grinder (unless you are a fool!).

    Any details needed on which to cut/which to splice?

  • dgott2 Sep 12, 2011

    well, the power cord is pretty self-explanatory (as in if a reader doesn't know which it is, they should just buy a new machine). I'll try to remember to look tonite, but as I recall, it's pretty clear which the motor wires are, since there are only two, but will double-check. I could email you a pictuer maybe.

  • dgott2 Sep 12, 2011

    or maybe I could email you a "picture" instead of a pictuer. They are harder to understand in French. ha ha

Be careful when you remove the 'shell' - the sping and the plastic pin that triggers the lid safety switch may be floating around in the machine. In my case, one of the screws of that switch losened itself - all I had to do was retighten and reposition.

Thanks for your posts!

I just finished fixing mine thanks to the above helpful solutions. I accidentaly broke off two of the three little latches that hold the side knob on. It seems to stay in place still. However I almost lost the little spring and white plastic cap from under the side knob. Luckily I can still enjoy the delightful click-click when adjusting the grind.

I used part of a heavy plastic laundry detergent lid to replace the broken plastic that used to hold the button ib place.

Thanks to wirving and dhelmkamp. Had the same situation where the starter button broke into the body. We successfully wired the power directly to the motor. Working like a charm now.

If you mean a chrome with serrated edges then that is a screw type ring that screws on the toggle switch on the outside to hold the switch tight in place against the body of the grinder. Place the ring over the toggle and hold the switch in place and screw the little ring on until tight.

Krups gvx1 complete disassembly


If you can't figure out how to diss-assemble the device yourself, I recommend that you take it to a proper service shop, making sure you call a few of them in your area and find out if they charge for inspection and estimates of repair, then see which one has the best estimate.

Mine did it as well. I had an electrician out to check out the outlet. He replaced the outlet, but it still has done it. It freaks me out, so I unplug it after use.

The grinder and the cover don't work i just got this for a gift about 6 months ago i cant believe it does not work. I try fixing but it still doesnt work the entire coffee box and the cover.


  • 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.

Grinder fell. Black "button" inside broke off.


Use just about any 2-part epoxy, clean parts with rubbing alcohol first to remove coffee oil and get a good bond.

I have an MKM6003 grinder, the blades are not moving fast enough


I had the same problem and had disassembled the complete machine. I found many videos on youtube how to take off the blades, but all solutions does not work. The motor does not turn when I turn the blades. The blades are screwed, but as long as the motor does not turn I can't disassembly the blades. After nearly two hours I was so frustrated that I take it off with brutally power and then I saw the problem: The thread (german: Gewinde) was made of plastic and was destroyed by the thread of the metal axis of the motor. The axis was wrapped with parts of the plastic thread. So, if you're not worry to disassembly this device you have to buy a new blade: http://www.bosch-home.com/de/store/product/Messer/00176106. Copy and paste the material number to search for that part in your country.

The on/off button comes off consequently machine isn't working


if you are handy the switch needs to be replaced. Soldering may be rquired and there is very little wire to pull. You can get a rocker switch at radio shack plus you need a triangular driver bit for base screws, It's really a poor design on a good grinder. You actually NOT have a switch and just hard wire it. I fixed mine for 3 bucks and an hours time
