Malfunction code 8 on Jura Impressa s8 (by 2 users)

Machine is almost 3 years old...put in cleaning tablet (cleaning prompt just came on)....after about 3 minutes into cycle, no water seemed to be going though the machine....is kept making noises like cycling when it turns on, but no water coming out of spout....then finally malfunction 8 lit up. Cannot open drawer either. please advise....machine has been great up to this point and I take care of it ++++ with filter changes and cleaning promptly.
