Jacuzzi J230 FL1 message

[Whisky Lad]

I have an FL1 error code on my Jacuzzi J230, sometimes it heats then the next day the heater light flicks on then off again whilst the pump is running. I have replaced the filter, tried power off then power back on with the filter out and the jets open but still it does not work properly.

The pump was refurbished a couple of years ago, it seems to be working OK but could it be the source of the problem?

Any suggestions gratefully received

Pressure switch.  Easy to replace and doesn't cost that much.    3902 or 3903 is what's in there now I believe.
