Add beans?? every time i press the coffee button, it grinds up the beans, and says add beans again and again -  of course it is full of beans - it dumps the unused ground beans in the drawer, and no coffee -  i have cleaned and descaled it.

the add beans to hopper signal most likely is triggered by the machine not sensing enough load put on the grinder (hence it thinks its out of beans) , this most likely is set by the grind (fine/course ) id say the grind is set to an improper size and the automatic sensor is picking up on that
another thing is the coffee / if its way too moist and not dry enough then its also going to trip the sensor as well

Sounds like the grind is too fine and the beans are not able to get to the burrs, try adjusting 2-3 numbers coarser. Remember only adjust when the grinder is running.

Sounds like the grinder is blocked. Set the grinder to the coarsest setting (largest number) and try a few more times. If still no luck then vacuum out all the beans, run the grinder again a couple of times and then add a small amount of fresh beans (not from a fridge or freezer as these will be moist and can cause problems) and try making coffee again. If after a few tries it still doesn't work then you will either have to remove the top grinder burr and clean both burrs (not recommended unless you are bit of a handy person) or you could try vacuuming out the beans again and letting the grinder dry out for a while (although unlikely, it could be wet from water spillage). Good luck hope this helps.

The beans are hanging up in the hopper and not falling down into the grinder...... wiggle it, give the beans a push, or go to a bean that is not so sticky....

The grind chamber is blocked, remove the beans and brew unit then clean the grinds chamber, then adjust the grind 2 numbers coarser and try again.

Hi
Without taking it apart. I would try opening the grind setting to the max (coarsest setting). Sometimes it will push the blockage through.

make sure you use very dry non-oily coffee beans

I haven't seen a Vienna in a long time so I cannot remember if there is a door for preground coffee, if that option is there, open door and press button to make a coffee if you get water, then adjust the grind and dosage on the grinder and try the auto function.

Sometimes the chamber between the grinder and brewer will clog up. Try: Open the grind all the way up to the highest number. Push the grind button and while grinding move the dose knob (the one with the + - sign toward minus. If it does not kick in and dose try it again. If it does take off then leave it on the high number for 3 coffees. Then while the grinder is turning move the two knobs back to whre they were. If this does not work you can reomve the brew unit and right above where it sits in the machine there is a trap door that you can open. Open it and shove someting like a straw up toward the grinder and you should get a bunch of grounds droppiing down. Then try the above procedure a couple more times. If this does not work you may need to google "Saeco repair" and send it to an authorized repair center.

Push the coffe brew button again. It should take right off and grind again.
