Initially, the coffee grinder was running, but at a higher pitch than normal (probable cause beans jammed, no beans getting to the grinding wheels).
We moved the beans around in the container. Took the beans out. Emptied out all the water, and waste bins. Turned over the machine to empty all the beans to make sure the hole to the grinder was clear.
Put every thing back. Now it does not attemp to grind at all. Press the coffee button and it goes directly to running water. It is as if you poured ground coffee into the top bypass bin.
There are no warning lights. Green light 23 (ready for single shot).
Any suggestions appreciated.

A bit of a late answer - sorry. I've had the same problem. I found it related to the type of coffee beans I used. If they have lots of oil on/in them they simply don't feed to the grinder correctly. Once I used a less oily bean all was back to normal.
Empty the grinder and see if it will run with no coffee bean in it. Some times debris will get caught in the grinder because it got mixed with the beans from the factory. If it runs your good to go. If not then the mother connection are not solid and it will run off and on at will.
Remove Coffee Maker's top cover. Slide coffee bean container off (after emptying it of coffee beans). Remove fixing screws (normally philips) securing the bean container platform. Remove grinder's bean intake rubber seal. Unscrew the grinder's fine/course selector, paying close attention to where it was originally fixed, from factory. 4 rubber bushing are anchoring the grinder in place, which can be seen from the front of the Coffee Maker (w/ door opened). Wiggle each rubber bushing through, as you pull grinder from the top. Grinder should come loose, after unplugging wires. - Good Luck
If the grinder jammed it might have been because the grind was too fine, try adjusting coarser then using the + or - lever to add more coffee for proper extraction. To clear jam remove brew unit and locate door to grinder chamber on left, vac out grounds, also beans in hopper. When clean run grinder and set to coarser, then add small amount of beans and test.
Try removing all beans from bean holder - then use a vacumn machine to remove the bits down amongst the grinder "teeth'. You may have had a small stone in your coffee and if so it may have jammed the grinder.
Once it looks clean, try making a cup of coffee without the beans in the hopper - you should be able to see and hear the grinder revolving and also hear the brew unit moving between the grinder outlet and the water inlet. If it all seems ok now, then add a small amount of beans back into the beans hopper and try making a coffee. If it still will not work, get it serviced. There's not much the average person can do inside these units other than to do more serious damage or kill themselves with an electric shock.
Hi Coffee beans empty is caused by the grinder running for about 15 seconds without filling the doser chamber. Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside on the roof of the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. From the left side of the drop chute pull down and back, and it will drop coffee. This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute. Once that is cleared go to the bean hopper. There is a lever on the right side of the bean hopper. Push the lever back to the largest number. You can push the lever to a larger number any time but it has to be grinding to pull to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can pull back to a number that was higher than the one you had it on, but only when the grinder is running.
I had a similar problem, and solved it by turning the grinder by hand against resistance. Apparently the grinder wasn't really turning during the cycle and needed to be cleared. If your beans are "hopping" this may be a different problem.
Hi The grinders run on a timer. If the grinders does not fill the doser in time you will get a light saying no beans. If this happens and there are beans in the hopper push the lever to the largest # and push the brew button again. This will clear the light and it should brew. If it is at the largest # already your beans are probably shiny and there is to much oil in the beans and this is what is clogging the grinder.
Your machine will probably need service. The water will cause damage to the grinder burrs. I can send you instruction on how to clean out the grinder on a Vienna if you provide me will your email address. You can email me at [email protected].
You are not the first person to do this. These problems come in at least once a week.
