Hi all I know this topic has been covered a few times looking but not sure on my fault.
Similar problem same cldf code pump and heater are both good tested separately. The controller is asking for temp a relay clicks in on the low voltage box but doesn't bring in main circulation pump relay. But if I turn 240v supply off for 5 minutes then back on the circulation relay will pull in and pump and heater will run for 30 seconds or so then drops out but controller is still asking for a temp rise. I'm guessing temp sensor is OK due to controller showing actual water temp and asking for heat on controller so not that. Also plenty of water in tub / filter also checked for air locks. Any help or advice will be appreciated.
Was running fine dropped it down to 26 degrees due to not using it for a few day turned it up to 31 degrees and fault started been fine since I bought it second hand 2 years ago.
