A steris service technician arrived onsite following the reported event.During his inspection the technician observed sparks coming from the wiring connected to the heating elements.The technician was not injured.The technician found that the wiring that connects to the heating elements was loose allowing the unit to short.Because of the loose connection of the electrical wiring to the heating element, the temperature of the unit was unable to fully heat up resulting in the reported alarm.The heat generated from the shortage caused the shield that covers the internal components of the wire to melt.The technician replaced the wire and heating elements, ran a test cycle, confirmed the unit to be operating according to specifications, and returned it to service.No additional issues have been reported.
