My Saeco Vienna Black Automatica Espresso maker will grind coffee only about one-fourth of the time. Other times, it makes whirring sound and then shuts off and red "coffee bean" light comes on.

sounds like your pump. When you turn steam knob on, you should hear the pump go bump,bump,bump. When hot water is turned on, you should hear pump run steady.

You can remove top panel and find the grinder.
Remove the limit lock screw and udjust in more fine grinding manualy. So now you can have more fine grinding.
Remeber that you have to move only two step at a time, then make coffee and then move again to more fine, this will avoid blocking the grinder and also burning the grinder motor.
Also before doing the above you can ckeck the grinding burrs if they are in good condition or they need to be replaced.

Yes, it is because of the grind, try adjusting the amount of coffee being used, there is a small lever to adjust the amount.

it is not a filter but a water softener and no need to replace. You need to pass thought it 2 spoon full of salt desolve with water and then flush it with water for 15 min until the salt will be cleaned. You can do this one time per month so to avoid any scale build inside the machine.

It could be the grind on the coffee or the red group o-ring and the 2 o-rings on the white plastic valve need to be replaced.

If you push the power button and the machine will not turn on and it a newer machine there is a reset button on the side of the boiler that needs to be pushed. This will get you [power again. If the machine is older than 3 years you probably need a new board or power filter.

Grinds are too fine and or the coffee chute is clogged.

Grinder is set to too fine. Lower grinder settings. Keeping the machine at current settings with drip extraction will result in brew group clogging, gear stripping, and/or dulling of grinder burrs.

Hi,

Try to open the steam knob and make a cup of water.
