Hi again
I contacted this site about a month ago with a chinease hot tub error code C L D F which according to the manual means heater unloaded ( heater broken or in bad contact ). I've since fitted a new control panel and checked for air locks , the fault is intermittent and when the fault occurs the circulation pump does not work. If I set the temp for the heater to come on nothing happens until I give the main control box where the relays are a bit of a tap and the it all fires up .?
Thanks Jon
