H.10: the involved roller pump was manufactured in 2014 and according to the analysis of the complaints database no further similar events related to this unit have been reported in the past.A livanova field service technician was dispatched to the customer facility.The reported malfunction could not be reproduced.However, the touchscreen was found not functional (it did not respond to touch input).Touchscreen function could be temporary restored by powering off and back on, however, the touchscreen failed after a few minutes of operation.Taking into account the collected information, it cannot be ruled out that a defective processor board was the cause of both issues (pump shut down and the touchscreen malfunction).Based on the above, the most likely root cause of the reported event is traced back to a defective processor board.
