During investigation testing, the customer-reported driver pause and restart with fault alarm was not able to be reproduced, but was partially confirmed.The cause of the customer-reported issue was the driver switching to secondary motor operation.The driver most likely switched to secondary motor operation because of an increased load of the motor gearbox assembly, increasing resistance in the system, which possibly led to the piston not being able to move, triggering the driver to switch to secondary operation.This issue will continue to be monitored and trended as part of the customer experience process.Syncardia has completed its evaluation and is closing this file.Ce 4297 follow-up report 1.
