So I have a beachcomber 578 spa, it was working fine since we bought this house about 6 months ago.
Then we got an FL code so I cleaned out the filter, checked for air pockets etc but ended up buying a new flow switch and then it worked again for about 6 weeks, I then bought a new flow switch as I thought the first one was faulty. The new switch did indeed work and the spa was all good for about another 2 months. Now I'm getting the same FL code once it reaches temp, circulation pump will shut off and it sits till temp drops below setting and then the FL code hits the panel.
Now when I unplug the flow sensor it fires up immediately and the I plug it in, that allows me to use the tub intermittently.
I tested the flow for ohms and it's behaving normally, but the board seems to be getting a closed signal from the flow sensor when its open, hence the solid FL?
Any thoughts?
I should mention I did have the pump rebuilt professionally too.
Hi Did you ever get to the bottom of this ?? I have the same problem and I'm now on my 3rd flow switch. Seems to me that something is causing the switch to break down.
Spa gets to temperature then shuts off - FL code
