S3 pump control knob unresponsive and unable to increase or decrease blood flow on bypass. E62 error noted on control panel. RPM remained fixed but flashed visibly to 0 RPM whilst blood flow readings remained constant.
If control knob turned to reduce or increase RPM, there was no response however, LED dot marked the current RPM value.
None
N/A
Sorin engineer called to investigate and replace the faulty unit. Thought to be a fault with the drive unit not the control panel.
