Following the reported event, the v-pro max sterilizer was removed from service and sent back to steris for evaluation.Evaluation results determined that when the steris service technician tagged out the v-pro max sterilizer and temporarily left the user facility to obtain additional service parts, he had placed a valve repair kit on top of the outside of the unit.The valve leaked hydrogen peroxide which entered the wiring sleeve tubing, which contained the electrical wires to the vaporizer heater.The hydrogen peroxide then contacted the wire insulation and caused a breakdown of the insulation material.This caused the two wires to contact and short.When the two wires shorted, this caused the wires to overheat and produce the burning smell and smoke that was observed by user facility personnel.Due to the damage that the v-pro max sterilizer sustained, the user facility received a new v-pro max sterilizer.The new v-pro max sterilizer was installed, tested, and confirmed to be operating according to specifications.The steris service technician who was performing service activities during the time of the reported event was counseled on the importance of not placing service parts on top of a device and to ensure the power to the unit is turned off before performing service activities.No additional issues have been reported.
