An area technical operations manager (atom) reported that an aquabplus 1000 sustained thermal damage during heat disinfect.
The system was running in heat disinfect, and before concluding, it had to be manually put into cool-down.
The atom stated there must have been some sort of interruption, but it was unknown if there were alarms.
Approximately ten minutes later, the screen went blank, and the system powered down.
The machine would not power back on after this.
During troubleshooting, it was discovered that the power switch had overheated.
There was a burning smell noted, and charring/thermal damage was present on the wiring and spade connectors on the back side of the motor protection switch.
There was no evidence of any smoke, sparks, or flames.
The atom confirmed the thermal overload switch was not tripping, and there were no local power grid issues in the area on the event date.
In addition to the thermal damage at the motor protection switch, a blown 25 amp fuse was found in the local power supply.
To resolve the reported issue, the motor protection switch was replaced along with the blown fuse.
New wiring was also ordered and will be replaced when received.
The atom confirmed the motor protection switch was available to be returned for evaluation.
Photos of the thermal damage were provided for review, and the ftp files were as well.
There was no patient involvement associated with the reported event.
