I noticed that my water temp was at 109, pump and jets are running constantly. Regardless of setting, standard, economy or slow. I have checked that it is not in constant circulation mode. Tried resetting but no joy. No error codes on the display.I can turn on and off the high speed jets, lights work ok. I am thinking a temperature sensor has gone, but not sure where to start, any help greatly appreciated.
