Other, other text: h6: event problem and evaluation codes: codes updated.One fluid warmer device was received for investigation.A visual inspection identified damage to the unit drain tube.A functional test replicated the reported temperature reading problem, confirming the customer complaint.The issue was traced to the unit printed circuit board (pcb), which was determined to be faulty.No root cause could be identified for the pcb failure.A review of the device's service record did not find any reports of this issue within a year of the unit's date of manufacture, therefore a manufacturing-related root cause was ruled out, and a manufacturing device history record was not deemed necessary.As the unit is no longer needed in service, the device was decommissioned.
