FLO Code

I started getting a FLO code and the hot tube would basicly shut down...I replaced the flow switch but still have problems. I checked the filters and they are clean and the tub is full. The new flow switch I got is somewhat different than the old one. The old one was adjustable... right now the tub shuts down after running a bit and when I take one leg off the flow switch the unit starts up again and resets. any help would be appreciated..


thanks

Was the switch an actual flow switch (http://www.hottubworks.com/SpaParts/HeaterFlowSwitches.php) or was it a pressure switch (http://www.hottubworks.com/SpaParts/HeaterPressureSwitches.php)?

I believe it is a pressure switch...looking at the pics...


Thanks

The one I took out is a Barksdale, Little General...the one I put in was smaller with no adjustment...both had two connections, is there any polarity?


Thanks

When you say the unit shuts down are you saying everything including the pump quits working, or is it just the heater? Does the pump operate like it always has? Does the spa have a 24 hour circulation pump? One test you can do with the pressure switch is to shut off power remove the two wires on switch and put the wires together. Then power back up and see if the spa will function. If so the switch is not the correct one or is bad and needs replaced. Have the heater off when doing this test. I am still not entirely convinced you are not have a problem with the pump.

Seems the spa just shuts down, pump and all, once it kicked out the breaker. Its an Emeral Spa, is there a strainer or filter on the intake at the bottom side of the spa? I replaced the pump about 12 months ago because of a leaky seal...I replaced both pump and motor at that time.. maybe the heater is getting plugged up? We bought the spa about 9 years ago. I don't know how long they generally last..

That is a long life for a heater. You may want to remove and visually inspect inside the manifold. Does the house breaker ever trip?

I have a Jacuzzi 220 and just drained andcleaned it and filled it up and plugged it in and got a FL-2 code for about 30 seconds. Everything works but 2 of the 4 sets of jets are not working. I went back and followed all steps to see if I knocked something loose but found nothing. What would cause this?
