It was reported that, during a pfa surgery, it was displayed an error code "pfs hardware control failure 0x4000000", which pointed to a faulty siu: a possible blown fuse because the fan does not spin and the red led could not be seen through the vent of the fan.
This error only occurred after the handpiece was plugged in to run the handpiece test: the handpiece could also be faulty.
The case was cancelled.
The patient outcome is unknown.
The results of investigation indicate that there was a short in the handpiece cabling that blew a fuse on the siu, which is a reportable malfunction.
