B3.Date of event: unknown.No information has been provided to date.Investigation summary: the affected device was received for evaluation in middling condition, with wear and tear on surface.The tank cover was found to be broken.After visual inspection, the device was unpacked, the tank filled with water, and a disposable was attached.After the start button was pressed the device was fully functional, and no alarm turned on.All the alarm tests were performed, and after each test the device had recovered and working well.The only thing that was noticed was leakage after the device was running for a few minutes.As a result, the problem was only partially duplicated.A new tank cover was installed, as well as tank gasket and o-rings, and this time no leaking was noticed.A temp check was also attached, and the temp was stable and in range.A cost estimate was created in the end per the customer's request.A review of the device history record (dhr) shows there were no observations or nonconformities recorded during manufacture to suggest an issue of this nature would occur with this lot of products.
