Reason for Recall
If the coolant level in the cooling circuit drops below a certain level, this may result in a situation in which the X-ray tube is no longer sufficiently cooled and the system will display the message "TUBE HOT, have a break". Several minutes later the system will block X-ray to prevent further damage and display the message "NO XRAY: TUBE TOO HOT".

Action Taken
An URGENT: MEDICAL DEVICE CORRECTION notification letter dated 2/23/22 was sent to customers. Which steps have to be taken by the user to avoid the possible risks associated with this problem? As also described in the Operator Manual, we recommend that the system operator checks the water level of the cooling circuit at least every three months and refills water, if necessary: 1. Open the filling gland of the cooling unit. The water surface must be clearly visible above the cooling ribs. 2. Replenish with water (drinking water quality) if cooling liquid is lacking. Please inform the service technician in case of lacking cooling liquid. How will the corrective action be implemented and what is the efficiency of the corrective actions? The tube cooling unit will be equipped with a water level sensor and the software will be updated accordingly. In case the coolant level drops below a certain threshold the following message will be displayed: Tube cooling water level low: Refill as per Operator Manual . Siemens will correct the error with a hardware and software update via Update Instruction AX002/20/S and AX004/20/S. Our service organization will contact you shortly to arrange a date to perform this corrective action. Please feel free to contact our service organization for an earlier appointment at 1-800-888-7436. We do not consider it necessary to re-examine any patients in relation to the issues described above. Following the correction, the cause is eliminated, and any recurrence of this potential fault is prevented.
