cal spa fl error

[swilloug]

I have a cal spa and it shut down and showed a code sf and we replaced the safety suction valve and now it says fl and we know that's water flow any help?

Is the water flow from the pump consistant? Maybe there is air in the system if it seems to be surging. Try removing the filter to see if the flow error code goes away.

Seen that on here tried removing filter and still has code....

ok so does the pump have good solid water flow coming out of the jets and it is not "surging". If so it can be a bad pressure switch on the heater.

the problem with that it wont come on at all it trip the breaker and says fl and if i unplug the pump the control panel works and lights works can you help?
