Tonight my heater was cycling on and off with error code of 128 r=5 code showing, any ideas? I seem to remember the last couple time this happened it was I believe the high limit switch or thermal switch. Can anyone also give me a walk thru on replacing what ever it might be.
On another note I have also noticed that when the spa and heater is turned on I'm seeing about 2 inch drop of water out of the spa, with the spa off and in pool mode water level is A'ok. I have checked all the auto valves for leakage and good there. Any ideas
See my sig for any additional info. Thanks
