In Response To: Re: Sundance FLO error - 2000 Altamar (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 thanks for your response. I did look at
: that, and I noticed that at whatever speed
: either pump the pump was on, L or H or both,
: it doesnt seem to move the flapper, it stays
: in a vertical position against the grey
: stem. While running, I tried moving the
: switch (by unscrewing it) which made the
: float move almost horizontally, but the
: error code didnt go away. I called my local
: store and they said likely the flow switch @
: $64. I'm just trying to narrow it down,
: hoping to replace the most likely culprit
: and avoiding the SPA repairman, whose
: service call is $70! Thanks for any other
: help you might be able to provide. Another
: thing, would this faulty flow switch cause a
: lack of suction in the two bottom screen
: intakes, as I did notice that the suction
: was low or non-existent, even w/ the filter
: totally off. Thanks in advance. Brad
