update:
I unscrewed the both junctions while the motor was running LOW and was able to get the jet #2 motor pumping water.
BUT the leak on the pump jet motor #2 became a stream ...
I replaced the #2 jet motor and now the both jet motors are working....
as you know I am newbie to spa and I was able to locate some parts that I bought recently for $550 because I needed NEW heater according to our spa tach.
when he gave me a estimate of how much the heater cost to repair , I told him I will buy the parts used and either call him back for fix it myself.
I got lucky that I found parts that was 90% comparable which came with updated CPU control box, updated top side controller, 2nd top side jet controller that shoes human body, 2 jet motors, CIRC. pump, heater, valve controller board and 5 valves which I have no idea where it goes, and fan.
so far , I replaced CPU controller, top side controller, and jet pump #2 with out the problem..
thanks for all your help and I have one last problem with limit heat sensor , anytime I set heat above 80 degrees the heater stays on than few hours later the WARNING DISPLAY reads DO NOT ENTER, CALL SERVICE.
It looks like My heat sensor is bad ...
any Ideals
thanks, again.
