How do you take the top off?

Found the 2 Torx screws at the front but the rear is still fixed. There are a couple of steel rivet like heads on the rear but they have no visible method of engagement. Would like to do a thorough cleaning of the powder chute and grinder.

The E8 actually comes apart pretty easily. The slightly oval 'rivet' looking things are actually just screws. They can be easily removed with a vise-grip or pliers. You will also have to remove some torx screws, so you will need to have a torx wrench on hand (actually 2 different sizes).
The E8 error is simply coffee grounds clogging up the mechanism. Once you have the covers off, it is still a bit difficult to get at everything but it should be enough. Simply leaving it open and allowing it to dry out thouroughly seems to work in itself. I have actually just run a hairdryer in there to dry out the hard to reach grounds.
However, I recommend plugging the unit in and watching it run through some rinse cycles. Use a flashlight to see, and then follow through with a dry cloth and get as much gound coffee out as possible.
The other symptom which can easily be fixed when you have the machine apart is when water/coffee is pouring out above the intended release, i.e., not out of the spout. This happens just from being dirty and clogged and is super simple to fix and very satisfying! The front grey, plastic, sliding cover pops off and exposes all the residual coffee gunk that is giving you trouble. Just take it apart carefully and clean and your machine will be as good as new.
Once you take it apart once, you will see it is not that difficult and you'll be happy:) We open it up about every 6-8 months now just to clean it. Trust me, when you see what builds up in there, you will want to also.
Or you could send it away and spend $300-$500 for an upgrade. The worst part of that is being without your coffee machine for a few weeks.
OF COURSE....be very careful when it is plugged in. Electricity kills :)
I compare all of this in difficulty to......well, my wife can do it. So can my 10 yr old son. Probably if you can put together a piece of IKEA furniture and you know what a torx is, you can do this.

At the rear of the unit is 4 blind headed self tap screws, just grip with pliers and unscrew the 2 top ones, this will release the top cover after removing torx by water and coffee areas.

How to replace thermoblock sensor?


To replace this part you will have to open the jura machine. I found this information out because I had the dreaded error 8 reading on my jura machine which stopped it from making coffee. To disassemble the jura coffee machine you'll need some special tools that I will talk about as I describe how to get to the sensor, make sure you get those tools or something similar.
The problem that you are having is the boiler is not heating properly (heating the water properly), so the taste of espresso will not be good. You need a high heating temperature to get good tasting espresso. This generally happens because the thermo sensor went bad and the electronic board is not sensing the proper heat because the thermo sensor went out.
1. Remove the drip tray
2. Remove the water tank
3. Remove the coffee cover and bean hopper cover (aroma cover)
4. Remove the cover for the pre-ground coffee shut
5. Now you will need to remove the cup warning plate that is stainless steel, it is fastened with 2 security screws. You'll need a Newelectronx t15 torx security screwdriver to take them out.
6. Now remove the top plate, there will be 5 screws fastening it down. Again use the Newelectronx t15 torx screwdriver to take them out. Pull it up to release.
7. On the rear end of the machine, you'll need to remove some weird oval head screws. The only place I could find the tool for this oval head screw was in the Newelectronx Coffee Tool Kit Set. Get the oval tool, which is different from the Newelectronx t15 torx bit and remove the next few screws. There are 2 screws - oval head, on the lower backside. Take off the rear back panel. On the left you'll find the mechanical parts.
8. On the boiler, which is the big metal part that is formed like an upside down tear drop. The thermo sensor is attached to the boiler with a screw - again use the Newelectronx security screwdriver to remove the security screw.
9. The thermo sensor connects to the electronic board. Detach the wire from the electronic board. Now the thermo sensor is off.
10. Replace the thermo sensor with a new jura thermo sensor that has the same wire colors. If the wire color is wrong the contact thermo sensor might not perform as it should.
11. Now put the machine back together. Good luck

Nespresso Magimix M250. power button pushed back into housing, How to access switch?


to get at the button you need to undo the two screws and the top and the two security screws on the front panel. The security screws are oval. I made up a tool by drilling an appropiate size hole in a bit of bar and then widened it out by angling the drill slighty to make an oval. once you have these out then you can tatake the front pannel off. the swithches are attached to the back of the front panel so watch out for the power cable. You will then need to take the switch housing off - a couple of torx screws and then it unclips. the button is on a hinge at the bottom and a prod to an electrical switch behind. I fixed mine with some flexable adhesive but it wont last Nigel

Breville BES820 Espresso Machine internal short circuit


noavatar.png
  • steve_s741
  • 4 minutes ago
Ok, I'll describe my own fix to my own problem in the hope that it helps others. First of all, the symptoms: your machine just stops working altogether; all lights go out; you try and turn it back on but nothing happens; then you realize half of your house has lost power. So you try and reset the circuit breaker, but you can't succeed until you turn off the machine at the wall plug.

The diagnosis: probably an internal short circuit.

This is what happened to my machine, and because it's out of warranty I thought I'd have a quick look at it myself. Turned out to be simple fix, so here goes...

Getting access to the wiring we need to look at is easy enough.

1. Disconnect power from outlet (obviously);
2. Use your Torx T20 to driver bit to remove 4 screws holding the rear cover, then turn the machine upside down and remove 2 small philips-head screws securing the base of the rear cover. remove the cover.
3. Gently bang the top die-cast cover from the back to try and dislodge it and move it towards the front of the machine (there are no screws holding the cover on the BES820, it is just a tight fit under some lugs). Your attempts to move the cover will be met with resistance. In the end I needed to thump it quite hard with my hand. A rubber mallet would probably be ideal, but I don't have one. Once you have pushed the cover forward by about 10mm, you should be able to lift the cover off.
4. Unscrew the earthing cable form the top cover and put the cover aside.
5. Now inspect the visible cables. Look in particular for any pair of wires that may be making contact with each other. This was what I found in my case. Two wires had been rubbing against each other, probably due to the vibration cause by the pump, and eventually had rubbed through the insulation to the point where the circuit was shorted. Smoking gun found!
6. If you find this evidence, you will need to a) add some additional insulation where the original has worn through (make sure it is heat and steam resistant, consult with your electronics store), and b) ideally, try to rearrange the cabling to keep some physical separation between the cables so it doesn't happen again.

When you are satisfied with your work, you can test it by plugging it back in and turning on at the wall. If you haven't replaced the covers yet, be aware that most of the visible wiring you see in there is running mains voltage, so keep hands clear!

Reassembly is the reverse of above. Don't forget to re-connect the earth lead to the top cover before replacing it. Good luck!

The machine goes through the motions, takes ages, but no coffee comes outchristyler@eircom.net


If you make a pre-ground shot but don't put any coffee in it, and it does the same thing you have a blockage in the brew head.
If it run normally, your grind is to fine. Turn the grinder knob to a larger number. It takes 3 times to change to the new grind.
If it still dribbles, remove the brew unit (behind the door)
Holding the handle, on the top left side is the brew head, there is an outlet pipe(rubber cup) that exits the front side towards the door. 2 screws hold it to the top. Remove the 2 screws while holding the manifold. Once they are removed, lift the l assembly off (becareful, there is a spring and inside a steel ball (don't loose it or your out of luck). Turn the brew unit upside down while holding the brew head in your other hand and the steel ball should fall out. If it doesn't come out put a towel down and tap the brew unit on the towel. This should force it out.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember thumbscrew, DON'T use the key to install the screen, use your fingers.....
Once the screen is out look at where the screen was. There are 2 holes. 1 big one in the center and a small one to the side.
Now use air to blow back through the opening where the steel ball was to clear the opening. Once its open, clean then reassemble. Brew unit on towel right side up. Drop the steel ball in first. Then the spring.
Then place the manifold on top of that with the pipe towards the door. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads. They should turn down easily, if not back them up a little more ( we are trying to find the old threads) and tighten. Install screen, and tighten with your fingers. The screen just needs to be flush with the bottom of the brew head.
Run another pre-ground without the coffee and rinse it out. Do this once in a while to prevent this.

How do I take my Imressa E8 apart?


Remove water container and empty beans. BE SURE UNIT IS UNPLUGGED.First, facing the unit, take out the three black torx screws from the bottom front. It makes removing the sides a little easier. Next, open the top lids, beans and water, and find the black pan screws in the top front and remove. Now, facing the rear of the maker, there are four screws disguised as buttons. Clamp on to the steel with a linesman pliers or you may need a side cutters. If using a side cutters, apply just enough pressure to grip and not cut. Remove screws counterclockwise. The top cover should lift up at this time. The side panels slide back to unhook from bottom and must be manipulated to release from front face. The side panel nearest bean grinder seems to remove a little easier than the water side. At this point, you may be able to clean bean grinder chute without further disassembly. If you need to service bean grinder, right side panel needs to be removed. Then remove the stainless torx screw holding on the bean cover to the grinding chamber. Adjust knob to full coarse setting. Next, find the two black torx screws inset in the bean container, probably have beans stuck above them. Remove bin. Do NOT remove the stainless torx screw on the top of grinder worm (on top of grinder blade)! From the side of unit, make note of clear and black wires on bottom of grinder motor so that wires will be put back on same terminals (can't remember if it was a dc motor). Remove wires. Make a mark on gear teeth of fine/coarse gear and gear ring of grinder to retain calibration. Now remove three stainless torx screws holding in grinder ***'y. Grinder ***'y should come out. Cleaning is easier at point. If you are to go further into the disassembly of the grinder, care should be taken because there are small springs and ball bearings in the ring gear and cutter.

Error 8 -- Has anyone ever taken apart the grinder in an Jura Capresso E8 to clean it? I have had my E8 apart a few times to clean it, but I am hesitant to take apart the grinder for fear it may have...


I am also experiencing error 8. This a great coffee maker but after several years of use following the normal cleaning instructions just isn't enough. I can hear the machine straining after making a cup. I want to clean all parts inside, I got the front off and can lift the top a little. However there are what looks like 4 rivets on the back 2 at the top and 2 at the bottom. I cannot see how to get the top off and am afraid of breaking it.
Do you have any instructions on how to do this? Or can you tell me how to get the top off?

Our coffeemaker leaks water from the bottom while brewing


There are many possible points that the leak can be.

All points of the water supply from water tank to the pressure pump then to boiler and finally to coffee group. All this are connected together with plastic or Teflon pipes with easy fit unions secure with clips

You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.

In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.

Water in Krups caraffe


look on the bottom for screws holding it together. they may be of the tamper proof design like three slots or just a hex shaped screw. for the hex a standard nut driver will work. for the three slot a special driver is made for it. A torx looks like an allen head screw but with internal star pattern. torx drivers can be purchased.
