During the visual inspection fluid ingress was determined, that means fluid was present inside the device.
A fluid presence inside the gas blender could be due to the cleaning procedure or to the accidental fall of blood or priming solution during the different phases of the cec.
The device, indeed, is not completely watertight.
Fluid inside the gas blender could cause short circuits, electrical problems and fluid leakages as in the reported case.
A review of the dhr could not identify any deviations or nonconformities relevant to the issue.
