I have an LA Spa Paradise model and have just completed a water change and now cannot get the pumps to activate (two pump system - pump 1 also runs for filtering and heating cycles). When I turn on the tub, and even after I reset the circuit breaker for the tub, the console display blinks the temperature and 3 blinking dots. I can adjust the temp setting up and down, and the air blower and lights work OK. I opened the bleed valves and loosened the plumbing fittings to release any air lock and I still cannot get the jets to turn on. I can hear the PC board click when I press the Jets 1 or Jets 2 button, but no pumps are turning on, not even momentarily. I have checked the two 25 AMP fuses for the pumps and they are OK. The tub is 3 years old and I have performed numerous water changes in the past without running into this problem. Does anyone have any ideas on what is going on here? Any assistance would be greatly appreciated.

Thanks.
