In my case, failure of the pump (during a PO's ownership) caused several traces on the PC board to fry. Someone had done a rather sloppy repair, which I cleaned up. I assume that the pump was replaced at that time but admit I haven't checked it other than measuring the current draw.
Rrgrassi, have you measured the current draw of your pump? It would be interesting to compare my 0.9 Amp to whatever yours draws. A larger initial surge is certainly one reason why mine will eventually blow a 1 Amp fuse but yours does not. Then again, my pump could have been replaced years ago and is again getting old.

Jeremy, actually, I have not done that yet. Now I'm curious...I'll try to do that this weekend and post the finding.
