If you are sure that your inductor is not blown up (mine was cracked to pieces, not visibly burned in any way, it was less than two years old) there is also a 20 Amp (I think) automotive type mini fuse that may have blown. It is probably yellow, located somewhere on the main controller board. Of course, if you find it blown, then the question would be why? But my money is on the controller board being bad, the new ones they are shipping have fixed that problem. That would be unfortunate though being out of warranty, as they cost a small fortune. You may be bettor off spending the extra two hundred bucks and getting a brand new unit with new cell and spare flow switch.
Another thing you could try is to call Haward Technical Support, I think the number is on your unit, and it might be 1-800-HAYWARD. I have gotten some good phone support from them in the past, helped confirm my controller board problem before I opened it up and saw the carnage.
