The fire alarm sounded and the fire department was dispatched to the user facility.All instruments were reprocessed.A steris field service technician arrived onsite and inspected the unit, and identified the over-temperature switch (ots) tripped but the contactor (ch2) stuck in a closed/energized position.The closed contactor allowed for the recirculation pump to continuously run.The water then drained from the washer during the cycle and the pump ran dry and causing excessive friction and heat.There are no combustible materials present in the reliance synergy washer/disinfector.Materials located in the bottom of the unit include stainless steel, high temperature rated wiring, ul & csa approved plastic, and fiber glass insulation.The technician replaced the recirculation pump and contactor, tested the unit, and confirmed it to be operating according to specification.No additional issues have been reported.
