Customer stated the cardiohelp would display lpm low flow and rpm read zero while on a patient/ perfusionist tried to re-initialize the cardiohelp by increasing the flow and restarting the flow.System would run for a few seconds and go back to low flow alarms.Alarms would still alarm and no intervention would clear the system to allow a restart.User manually turned off systems and rebooted the same problem occurred.New system was put on patient and with no adverse effect.Arrived on (b)(4) 2012 tested system to factory specs tested ok.No problem found.(b)(4).
