The UV bulbs need to be replaced periodically. This was most likely negligence.

  Article says the machines were maintained. It doesn't matter if you purify water then expose it to room air. It's going to get contaminated again.

    There was a maintenance record. Not that the machines were maintained. Having visible biofilm I don’t think there was done anything on them.

      This seems a bit of a conspiracy thought. What if the machine was designed poorly or something extraordinary happened causing the film to build.

      The machines were operating normally when the investigation was done. Why assume the UV light didn't work and maintenance reports were faked when the easier explanation is the machine was just dirty?

    The 'machines' may have been maintained, it doesn't mean the filters installed on the waterline before the machines were. Properly functioning UV filters kill bacteria, there would be no way to introduce bacteria into the system from the waterline if the UV filters were working adequately (assuming the upstream carbon filter wasn't acting like a reservoir exceeding the specs of the UV filter also due to lack of maintenance). Since the other machines elsewhere didn't have these filters, it's safe to assume nobody had them on the maintenance list and serviced them.

      It's an ice machine. Have you seen one? The trays the ice are made in are open to room air. No conspiracy theory needed.
