Ok I have a 2002 Sundance 850 Altamar the tub worked fine yesterday today we went out to use it (its 14deg here) my son lifted the lid then tripped and dropped it back down not sure if this has anything to do with it but thought i would mention it. I started getting a flo and flow 2 error message. I replaced my circulator pump 2 weeks ago as it was shot. I checked my flow switch with my fluke and it opens and closes fine circulator pump turns on I open the wires it turns off when i turn on my pump 1 1st speed OK 2nd speed it shuts down turn on light it shuts down turn on pump 2 shuts down air blower works fine by shut down i mean any pump previously on turns off when I hit the pump 2 or light i get a -l 8 -l F on my display screen is my control panel bad maybe from the cover dropping on it in the cold weather. when the circulator pump was bad i was still able to turn all of my jets on without a problem tub is heating fine stayed at 98 -96 all night and it dropped down to -4 last night. I checked pump 2 and its free i can not frozen. I ordered a new flow switch but i cant see where it is bad ohms open and short closed. Any ideas
