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
