(b)(4).Device evaluation by manufacturer: field service engineering (fse) contacted the customer over-the-phone to address the reported event.Fse troubleshooted with the customer and instructed the customer to replace the column.The pressure was reading 8.98 mpa thereafter.There were no further high pressure alarms.The instrument was verified as operational.There was no further action required by fse.A 13-month complaint history review and service history review for similar complaints was performed for serial number (b)(4) from (b)(6) 2017 through aware date (b)(6) 2018.There were two (2) similar complaints, including this ticket, found during the searched period.The g8 variant analysis mode operator's manual under chapter 6, troubleshooting, states the following: 6.3 error messages: when consulting with technical support about a problem, please note the error message and error number.In addition, if you follow the suggested solutions in this section and are still unable to resolve the error, or if you encounter an error message that is not noted, contact technical support.General error messages: with these errors, the assay stops and the analyzer immediately enters stand-by state.100 pressure high: the pump pressure exceeded the upper limit (15 mpa) set in the pres high parameters.When the filter or column replacement period has been exceeded, first replace the filter or column.If the pressure is still high, remove the inlet and outlet flow line around the column and filter, and determine which part is the cause of the high pressure.Then, contact a technical support representative.If the pressure displayed on the screen is: greater than the pressure on the column inspection report + 4 mpa, then replace the filter.Less than the pressure on the column inspection report, then proceed with priming the column.The most probable cause of the reported event was the column needed to be replaced.
