Likely same problem as I believe I have. It may have ingested something it could not digest. Perhaps interfering with impeller on pump or caused a "ding" or damage to impeller that could be quieted by simply taking a file to clear the misformation. I am looking for access to pump/impeller information and this is the first that caught my eye.
