kentp Posted February 25, 2016 Report Share Posted February 25, 2016 Hi all, first post here so please forgive me if I do something wrong... I have a 12 year old Southwest Spa with HydroQuip guts (product HQ6000 - order code CS6220-U). A few weeks ago I drained the tub and cleaned it like I do regularly, and after filling it took twice as long to heat back up. Normally it takes roughly 4 hours to heat and this time it took 8. On top of that it has been having a hard time keeping the temperature at 100. Where before the pumps/heater only came on as needed, now they are running all the time. Last night I noticed that the temp has begun to fall as it was at 96 and holding. the top side controls say that the heater is on (or calling for it), but I don't see the heater light on the controller lit. All other functions and flow seem normal, and there are not any error codes or warning lights. I will put an ohm meter / multimeter to it this weekend, but my initial thoughts are that the heater may need replacing. Thoughts? Suggestions? Any help is greatly appreciated. thanks, Kent Quote Link to comment Share on other sites More sharing options...
