The customer reported complaint for the platform displayed an error message user advisory (ua) 07 (discrepancy between load 1 and load 2 too large) was confirmed during archive data review but not during functional testing.This indicated that the load sensing system has detected a weight/load imbalance between the two load cells.(ua) 07 indicated that either the patient not oriented on the autopulse platform correctly or the patient has shifted during compression.Additionally, unrelated to the reported complaint, platform failed functional testing due to the user advisory (ua) 08 (motor controller fault detected) error upon powering on the platform, error was cleared after two restart attempts.Furthermore, the autopulse was tested using the 95% patient test fixture (lrtf) and failed with user advisory (ua) 16 (timeout moving to take-up position).The motor controller board was replaced and brake gap was cleaned to remedy these issues.The autopulse platform is a reusable device and was manufactured on 09/30/2014.Therefore, this type of issue is characteristic of normal wear and tear for the life of the device.Visual inspection was performed and found no physical damaged observed upon receipt.The data archive showed multiple user advisory (ua) 07 and user advisory (ua) 08 error messages on the reported event date.After replacing the defective parts, the platform was further tested for 25 minutes with large resuscitation testing fixture, (lrtf) equivalent to 250 pound patient and passed all functional testing criteria and met all required specifications.Historical complaints were reviewed for service information related to the reported complaint and there was two similar complaints reported for autopulse platform with serial (b)(4).Ccr (b)(4), reported on (b)(6) 2015 and ccr (b)(4), reported on (b)(6) 2017.The load cells were replaced to address these complaints.
