Manufacturer Narrative

A field service engineer (fse) conducted a site visit and was able to confirm the reported problem by reviewing the error log.The fse suspected the xp107 bf pulse motor cable was causing erratic motor movement.The fse replaced the xp107 cable and tested movement with no issues recurring.The fse validated the analyzer by running quality control (qc) with results within acceptable range.The aia-2000 analyzer is functioning as expected.No further action required by field service.A 13-month complaint history review and service history review through aware date of event for similar complaints was performed for serial number (b)(6).There were no similar complaints identified during the search period.The aia-2000 operator's manual under appendix 4: error messages states the following: [2239] b/f probe 1 purge failure cause : the overflow sensor failed to detect liquid even after the washer was purged.Solution : air may be trapped in the washer tubing.Purge any remaining air by performing the priming operation and check for the presence of air in the washer tubing.If retry fails, contact tosoh service center or local representatives.The most probable cause was due to failure of the xp107 bf pulse motor cable.

Event Description

A customer reported probe 1 shuddering with no movement and 2239 bf probe 1 error on the aia-2000 analyzer.The customer powered down and versioned up the analyzer, and performed all set home but error recurs.The analyzer is down.A field service engineer (fse) was dispatched to address the reported event, which resulted in a delayed reporting of patient samples for beta human chorionic gonadotropin (bhcg).There is no indication of any patient intervention or adverse health consequences due to the delay in reporting of patient results.

Manufacturer Narrative

The xp107 bf pulse motor cable was returned to the tosoh instrument service center (isc) for investigation.A visual inspection was performed and no damage was found.The cable was also tested via a digital multi-meter (dmm) check running continuity for open and closed circuit and the cable performed as expected.The isc visual inspection and dmm check could not confirm the reported event was due to failure of the cable.The most probable cause is unknown, cause not established.
