Customer Question

I have just replaced a new spa pack that is connected to a K9 top side controller; however it will not operate automatically, that is when I press the jets manually it will work fine, heats etc for 20 minutes then turns off until I hit the jet button again? The topside controller shows FLO when first turned on, this goes out the moment I press the jet button. When I press the temp button the light comes on and off, I have replaced the topside controller with no change?
As mentioned the spa appears to work fine manually, no tripping of power, all jets work and it heats up fine when I continue to press the jets on manually.
Any ideas?

Is the circulation pump itself running?

Is FLO on screen the entire time the jets are not on?

Flo is on the moment the jets stop, the pump works on speed 1 and 2 just does not come on automatically as it used to. The top side controller also has issues, press the temp up button the light goes on and off, this was also replaced making no difference. Is there a wring issue on the new spa pack? I have looked and everything appears to be right, and like I said it all works (other than the topside controller) if I press the jets manually, the heater, both jet speeds and the temp display.

there appears to be a wiring difference.

Were any functions missing prior to spa pack replacement?

Topside controller worked fine, the spa pack was replaced due to the heater failing, due to the age of the spa I thought it wise to replace the whole pack complete as there was a little corrosion etc. forming on some of the resistors and the like.
