The most common leak issue I've seen is on the plumbed-in kit where the pump's connection loses its seal. If you aren't manually filling your jura, check that pump outside your machine. You may be able to give a fresh cut to the line (keep it straight!) and add plumber's tape to the fitting and fix it right up.
This issue sounds like it involves something like a k-cup/pod?
Check that all reservoirs are empty (the model I work with has multiple) and see if there are needles that poke into the pod wherever that is supposed to go (if so, a paperclip might clear debris).
