Question about Jura Capresso Impressa E8 Espresso/Coffee Maker

3 Answers

For some reason the grind time has been reduced producing much weaker coffee. I re-checked the grind setting to be sure it was set on "robust", but even when set to "strong" the grind timeis only about 5 seconds. The manual says it should be about 10 seconds.

    My problem is not with how fine or course the grind is, I know how to adjust that. I have had this unit for more than 2 years and up until recently everything worked fine. Lately though I noticed that the grind TIME seemed to be shorter than usual and also noticed the the coffee was weaker given the same setting that I always used. So, I timed the grind cycle when set to "strong" and found that it is much shorter than the manual indicates that it should be. In fact, about half as long. It seems that it is grinding only for the amount of time that it should be for the "weak" setting when it is set to the "strong" setting.

    Sorry, I forgot tyo confirm that my machine is indeed the E8 model. However, the grind selector on my machine in on the right rear of the machine in the back of the coffee bean hopper.

  • p_alford Oct 11, 2010

    This is NOT the problem. The grinder is working just fine excpet for the LENGTH OF TIME it is running. I noticed that the running time is shorter than it used to be, and I have confirmed that it is shorter than what the manual says it should be.

  • p_alford Oct 11, 2010

    OK, how do I go about doing that?

  • p_alford Oct 12, 2010

    Anyone know how to go about changing the circuit board?

  • p_alford Oct 12, 2010

    Yeah, I had already mentioned that was the first thing I checked. It's set to robust, as it always has been. It seems that the consensus is that I have a bad circuit board. I'm wondering how I can get the circuit board and if anyone knows how to change it.

That rarely happens on that machine. infact it makes the best coffee. Push and hold the P button until you see word FILTER. Now turn the Rotary Dial until the word AROMA is displayed. Push the button inside the Rotary dial and select from ROBUST. Push the button again to confirm your selection. Now push the P button again to get back to making coffee, indicated by READY in the display.

Okay,

Replacing the circuit board is not a end users serviceable part so asking how do i replace the part is not going to get a simple answer.

First you need the part
Then you need the tools

I looked up repair info on this trying to find the part for you and this unit was discontenued so finding a part will be riduculas waste of time and your money, from the reviews on this machine being the wrose investmate for a machine, I would simply tell you my advice repair or replace.

Repair about $150 bucks

let me know if you want a repair solutions locally and i will try to find a shop just give me a zip code.

Yes the board needs to be replaced it contans the grind times and if there way off then you are correct but the replacment will prolly cost more then the thing is worth,

    On the left side of your machine if it is the Impressa E8 there is a rotary switch. You need to turn it to more grinding degree- the smaller the dots the finer the grinding.

    The grinder may only adjust while the grinding gear is running. So be prepared to rotate it after you press the coffee button. Try to adjust only a small turn at a time in order to avoid the blocked of the grinding burns.
    The above is described in manual page 7 chapter 2.5.

    The most frequent problem is that the beans oil along with small parts of the coffee beans have created a small layer in the grinder funnel which blocked the beans flow freely in the grinder. So with the preset time the number of beans that should be grinded is much less than the required.

    So you should remove all the coffee beans from grinder, use of a vacuum cleaner will help, and then you should try to clean all the oil and beans remaining from the grinder so the coffee beans should enter the grinder freely.

    The grinding times for the three different selections is control from the electronic control panel and is preset from its hardware.

    Unfortunately the most possible reason for the change in time is a malfunction of the electronic board and only solution is to replace the control board.

    Electronic control board is located behind the front top panel. In order to remove the front panel first you need to remove the back panel and the two side panels. They are secured with four screws each and they are obvious to see. The front panel have a screw in each corner and you must remove the drug drawer first. In order to remove the control panel you need to take out all wire plugs but remember to take some photos before so you will have records if you forget about something.

    Also please note out of ten difficulty is only seven to replace the board however is delicate job and need to have a similar experience before either you have a lot of possibilities to damage the new board.

    Also please remember to remove the power plug of the machine.

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.

Tip

Espresso/coffee not coming out


If you are having a problem with your espresso/coffee machine with water coming out of the nozzle of your espresso/coffee machine or there is a smaller amount of water then usual that you notice coming out of the nozzle area, locate a pin or a sewing needle and clean the nozzle head with the pin or sewing needle. This actually happens due mostly to the grind level of the beans that most people have there unit set on. When you first get your machine there are actually no problems grinding your beans to the finest setting but as time goes on these small grinds end up building up and eventually clogging the nozzle head due to the fineness of the grind and the oil that is found in coffee beans. This also may require more then one cleaning with the pin or sewing needle on the nozzle head depending on how fine the grinds are that you use in your machine. All espresso/coffee machines should have this done often especially if you are used to a finely ground coffee. The simpler solution would be to turn down the grind setting but preferably more people set there unit to the highest grind setting thinking there will be a difference in the taste or strength or robustness of the coffee or espresso. If the beans are not ground at the maximum setting by turning the fineness of the grind down you not only save yourself the amount of time to clean the nozzle head with a pin or needle. You also prevent clogs of this finely ground amount of coffee from backing up in your water path within the unit as well. If the fine grounds are not removed in this manner eventually you can cause damage to the machines water pump as well.
Thanks again
Rick
As you can see from other customers replys this does work very well at alleviating this clog issue in the nozzle head

Grind time is short, puck is wet and sloppy, espresso weak


Sounds like you might have more than one problem.

From page 12 of the manual... NOTE THE LAST LINE.
"8. ADJUSTING THE GRINDER
......
• Open the lid of the bean container.
• While the grinder is running turn the grind selector switch to
the desired position (Fig. 6).
-The smaller the dots, the finer the grind.
-The bigger the dots, the coarser the grind.
Important:
The grinding grade can only be adjusted while
the grinder is actually grinding."

HI
You can run more water through the same grind you are using now or you can trun the big knob in the bean hopper to a larger #. That will make the grind coarser. You can turn the knob to a larger # anytime but to turn it to a smaller # it has to be grinding or you will damage the grinder. If you have 2 knobs in the bean hopper, you can turn the small knob down towards the -(minus) and reduce the amount of coffee in the brew unit.

Saeco odea giro is not grinding enough coffee.. the pad is like half or less than that.. it seems like a pcv problem .. HOw can I reset or reprogram to grind more coffee?


Hi,..These saeco models have a auto adjusting grinder. If the brewunit is heavy or in other words overloading, the machine will reduce the grinding time lesser to produce less ground coffee.If it senses the brewunit is smooth and light in loading (compressing the grounds), it will increase the grinding until it reaches the optimum dose. So it is important to clean and lubricate the brew unit at all times. Hope it will solve the problem. Good luck.

My A-9 Coffee grinder no longer grinds coffee. Have cleaned it and checked it out and nothing. The motor runs but no grounds. Thanks for your help!


This fixes almost all the "beans will not feed or beans will not grind" problems caused by coffee bean dust packed in the burrs. Oily beans cause this problem more fequently.
a. Pour all the beans out the top.
b. Open the settings up all the way and see what else can be poured out. Use your shop vacuum to **** grounds out the spout and backward out the bean bin.
c. Pour in some instant rice and start grinding. Reduce the grind to a small setting like six and then open the settings all the way again. (The grinder will not start at a low setting with the rice in it. If you let it stop, open the settings to about 16 before trying to restart.)
d. Pour out the rice and vacuum out the ground rice.
e. Adjust the grinder to your favorite setting and try a coffee grind. Grind until most of the rice dust is expelled (any remaining trace of rice dust will not affect the flavor of the coffee).

Remove brew unit and check the grounds chute from the grinder, if that is clear, then re-insert unit, then when the grinder is grinding adjust to a coarser grind.
