The suspect pump was returned for evaluation.The event history log (ehl) was reviewed, and no service history was identified within the previous 12 months.Visual inspection and functional testing were performed, which confirmed that the downstream occlusion (dso) seal was cracked.Corrective actions included replacement of the printed wiring assembly (pwa) board, dso seal, dso sensor, and upstream occlusion (uso) seal.The probable cause was determined to be unknown.The device passed all functional testing after repair.
