I assuming I did this correctly, with the recirc pump on, I tested for continuity on the flow switch at the board, and I got between 122-125 ohms fluctuating. I guess I'm off to the SPA Store Monday w/ $64 so I can hopefully get it heating again! John, Thanks again for the additional help on this, I was smart enough to figure out where the problem was but the specifics I needed help on. I'll post back on Monday and let you know how it goes. :) Brad

: The flapper will be against the gray stem when
: water is flowing through the heater, whether
: it is due to the circ pump or pump #1 is
: immaterial. This means that you have
: narrowed the FLO problem to either a bad
: flow switch or a bad board. The differential
: diagnosis is now made by checking the flow
: switch for continuity while water is flowing
: through the heater. Proper continuity means
: the board is the problem. Any resistance
: means the flow switch is the problem. If you
: do not have the means to perform this test
: you can just replace the flow switch first.
: That is usually the culprit nine times out
: of ten.

: You have at least successfully ruled out any
: obstruction as water is flowing with
: sufficient force to push the metal flapper
: against the gray plastic stem of the flow
: switch.

: John
