    My DBM-8 slowed and then stopped grinding three days ago, after 2 years' ownership. cuisinart does not offer any repair service or recommendations. not exactly a "green" company in my book, expecting me to toss it into a landfill and buy another. if anybody has any experience in repairing such a problem let us know. i'm going to try disassembling it this weekend.

    I think it is the switch on the ground coffee bin but I can't find any parts site.

We are on our second and last machine; after this DBM 8 goes out, I am going to find the most basic grinder I can and stick with it. That said, I fixed ours by removing the clear plastic reservoir where the ground coffee ends up, and then removing the build-up of coffee grounds around the exit chute where the ground beans enter the reservoir.
So, slide the reservoir out, just as you would when emptying it in to your coffee maker and set it aside. Have a flashlight ready when you tilt the grinder forward. On the back side you will see the hole where the ground beans empty into the reservoir. Take a toothpick and get rid of all the clay-like coffee reside that has built-up around that hole. Use a can of dusting air, if possible, (the aerosol "can" type used to blow dust particles from your computer) and blow away all possible ground coffee residue in the hole and around it. This will allow the reservoir to seat snug and flush again. This process fixed ours and I don't know why for sure, other than I suspect, the clay like build-up of coffee grounds, over time prevents the reservoir from seating properly and it has to seat perfectly to work. Good luck.

I took this solution one step further with my DBM-8. I removed the bottom cover and found the 4 screws at the corners (you need a long Phillips head screw driver) and removed them enabling me to take the top off the machine. This way I was able to get into the grinding chamber itself. That clay like buildup that Marc mentioned was all around the burr wheel. I scraped it all out as best I could then reassembled it and it worked better than it had in a while.

    To add to Jason6486 after struggling with this tonight. You will need to completely unscrew (counterclockwise) and remove the hopper before removing the 4 screws. Also, to remove the bottom cover, there are screws under the rubber footpads. Plus there is a 5th screw in the grind catcher area directly underneath the timer switch. After cleaning out all the old grinds and vacuuming the timer switch like Jason6486 suggests, the grinder runs like a top.

I bypassed the switch the detects the bean hopper, but cutting the red wire connecting it directly to power. Works fine now

Marc's suggestion may be right on. i did just that a few weeks ago. disassembling from the bottom hoping to ID fried wires at least, i noticed built up very fine grounds and cleared it with a small jewelers screwdriver. not finding any wiring problem, i had given up and reassembled but tried it one more time and voila, it worked!
again, i don't think i will support cuisinart, a company lacking both customer support or a repair service. surely they must know such a problem may occur.

I have the same unit it has been flaking out for a while. Seems to be a switch problem, I have cleaned , poked, prodded this thing nothing seems to be a real solution so much for trusting consumer reviews. I had a DeLonghi grinder that took 10 years to break why can't I find that model again ?

Hi I have one of these and I know it is frustrating at first. There is quite a lot out there on the net about \'pulling a great shot\' some of it conflicting some of it intensely obsessive.

So here is one I found useful

http://coffeegeek.com/proreviews/detailed/pavoniprofessional/operation

I will also try to tell you what I believe will help you get going.



Number one buy decent coffee.

Like all espresso makers it the combination of grind and tamp that will lead to a good shot, this is especially true with the La Pavoni.

You must grid your own beans for this machine, or at a push if you buy from a roasting house get them to do a selection of different (fine espresso) grinds for you, mark the packs and try them all and select the best. Here in the UK coffee sold pre-ground is just to course for this machine.

So if you are grinding your own you need to experiment and every time you buy new beans you will notice you have to do it again to calibrate the grind.

A grind will be to course or the tamp to light if the coffee flows to easily and takes less than about12-15 seconds with a relativity moderate pressure on the handle again this is something you need to get a feel for. you really don\'t want to be straining to pull the shot as this means the grind is to fine or the tamp is to hard, so it is possible to have a good grind coupled with a wrong tamp.

I tend to use just two finger to pull down on the handle this way I can feel more easily how the flow is going I also have a look at the coffee coming out of the spout when you have it just right the flow kind of bends at the top rather than going straight. Also it can be quite easy to damage the machine but pulling too hard on the handle.

If you find that you are pulling down for to long and nothing or next to nothing is coming out then the grind is to fine or the tamp is to hard or both. I think in general I would try adjusting your tamp first before changing the grind.

I suggest experimentation and stick with it, it really is worth it when you start to pull great coffee shots.

Also look out for overheating the brew-head this can lead to a bad taste it can get to hot after pulling 4 or 5 shots try wrapping a damp cloth round it for a while to bring the temp back down.

So I am sorry if I have rambled on a bit but there are no hard and fast rules here.



All the best

How do I stop the grinding when starting 2000 Astro Van


Hello Anonymous...

To inspect the teeth on the ring gear requires the inspection to check the full 360 degrees of the ring gear. Looking past the inspection cover to examine a small portion of the ring gear may reveal no issues, but only for that section. Eventually the ring gear will end up positioned above the starter drive gear which will skip across the bad teeth creating your grinding noise when you try and start the Astro,.

I have a 2000 chevy cavalier and there is this grinding noise in the front end. it sounds like its in the middle but the noise is in perfect rotation with the tires. it just started with grinding but now...


From what you described, it sounds like you may have a CV axle going bad. The tripods are located somewhat near the center of the vehicle, near the transmission, and the fact that it gets worse in turns helps to reinforce my guess. Try this. Go into a large parking lot where you can make a minimum radius turn ( with your wheel turned as hard as it will go.) Do a few circles in each direction. If the sound gets substantially worse while turning than it is while driving straight, this is a good indicator that your CV axle is going bad. If that's the case, don't delay in getting it repaired. If it goes out, it will leave you stranded.

CV joint. Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

I think you have to be careful in how much water you put in. I had the same problem the first few times I used it. I started to only fill until the water just met the 10 cup mark, not over it. I have not had the problem since.
