(b)(4).The homechoice (hc) device evaluation was completed.The event history log review showed no keystrokes, programming, or use related events that indicated and/or contributed to this return instrument test/evaluation (rite) failure.A review of the service history revealed no failures or problems that were the same as, or similar to the rite failure and there was no indication that the parts replaced during servicing caused or contributed to this event.The external/internal inspection was performed and the device passed, along with all of the electrical testing.The fluid volumetric accuracy test that was performed, had failed with the original piston foam.However, when a test article, piston foam, was installed, the device passed the accuracy confirmation testing.The original door piston foam was too deteriorated to place back into the device.An inspection of the door assembly found the door piston cracked on the top edge and at the left disposable.The evaluation concluded that the cause of the failed fluid volume accuracy testing was the deteriorated piston foam and a cracked door piston.The piston foam and the door piston were to be scrapped and the device was sent for servicing.This issue is being further investigated through a capa.Should additional relevant information become available, a follow-up report will be submitted.
