Coffee not coming out of the front taps, coffee & waste beans both ending up in the waste tray, can you please advise thankyou. model type 889

Question edited for clarity.

You are aware that we are Fixya and not DeLonghi?

These machines are problematical in home use, and when they go wrong you just pick them up and take them to the nearest Service Centre. Too many models and they all have issues.

Different machine, same issue

Have you changed your type of coffee beans or grind setting recently? First of all I would recommend removing and cleaning the brew unit thoroughly (as per cleaning instructions) to eliminate any cleaning issue here...
This is sounds like the flush valve is not working correctly. The flush valve ensures that all unused liquid in tubes is flushed into the driptray and that all solid coffee (dry pellet) goes from the brew chamber into the waste container. At the end of the coffee cycle when the pump stops running, the piston in the brew unit usually moves one last cycle and squeezes the coffee pellet in the chamber one last time and the flush valve operates so that all waste liquid is flushed from the coffee pellet to the drip tray. If your pellet is wet, then this final flush is not working. There may be a blockage in your flush tube or the flush valve may be blocked. These usually block up if you don't run a cleaning tablet through the machine regularly.
My advice is to remove the driptray grill and check that the tubes running into the tray from the brew unit are not accidentally squeezed closed or blocked. Good luck.

What you see in the waste tank dry coffe powder?

Coffee Beans were roasted by local business,believe they were either not roasted enough or over roasted causing the problem, I have since tried Supermarket(Vittoria Roasted Beans) and machine is working perfectly.
Thankyou

The brewhead is blocked the machine will have to be stripped and cleaned and the o rings replaced.

Ok, If you pull out the waste water tray and bean tray, along with the brew unit ( by pushing the lever that says push) turn the brew unit upside down and you will see a layer of waste coffee grinds on a circular metal plate, just rinse it under a cold tap, dry it off and reassemble
Also you may want to try rinsing other parts of the brew unit and give it a general clean if there are any other build-ups of coffee grinds :) 

sounds like you have a bean jam post your model i will send you the guide on how to fix this it is too long to type here

I do have the same problem.

I have removed and cleaned the grinder mechanism.

Being an electronic technician I did have a look and tried to find what method they use to detect that the new beans reservoir is empty and I did not see any kind of detector.

I suspect that they monitor the motor current to do this. If it is so would'n it be possible to desable this fonction since it is more then evident when the reservoir is empty or about to be?

Any body knows how they do monitor the status of the new beans reservoir?

Hi, We had a similar problem and it turns out the beans we were using were too oily and clogging up the works. We solved it by using a slightly more coarse grind (and brewing a stronger cup), and by buying only the best beans (oily beans don't make coffee stronger, just means they aren't good beans and by roasting longer can make the coffee taste stronger). Try Barefoot Coffee Roasters (I don't work for them, just love their coffee). We also use the cleaning tablet more often than prompted, and clean the inside of the flap when we dump the grinds. Good luck. Great coffee, but finicky machine!
