A steris service technician arrived onsite to inspect the sterilizer and found the root cause of the reported event to be a failure in the water pump of the steam generator.As the water pump was not operating properly, this allowed the electric motor to stop rotating and overheat subsequently causing the reported event to occur.The wire insulation within the electric motor had evidence of charring.The unit was installed in 2005 making it approximately 14 years old.The technician replaced the water pump and the electric motor, tested the unit, confirmed it to be operating according to specification, and returned it to service.No additional issues have been reported.
