I have a cal spa 9000. The main pump is cycling on/off and the safety suction light is on. The filters are clean and the intakes are unobstructed. Any ideas?

SOURCE: Bought 2002 Cal Spa and the motor starts and stops repeatedly

It sounds like the motor is running to hot and cutting itself off as a safety. Make sure that the wiring is correct, and if it is you may need to replace the bearings (if the motor is running very loud or making a grinding sound). or you may just have to replace the motor.

It could also be a problem with the control panel. Do you hear the relay click on and off with the pump?

Check the voltage at the back of the motor with a voltmeter and make sure that it is 110vac and that it is there throughout the cycle.

SOURCE: intake to filter has little suction

Hello,
If you are still looking for some solutions, here they are.
Start by plugging both your out put and input in the pool
or simply close the plungers
If you are uncertain the flow sensor is ok then blast it out with the garden hose. Make sure it swings freely
now take out your cartridge and blast it too
now remove your hose from the inlet to the pump
even though you may be skimming and things go in the basket hair still gets through and cloggs up in front of the filter
this also will happen with out a skimmer
Put it all back together and now open the top bleeder on the cartridge cover
open outlet side hose first
when water starts comong out the bleeder open the inlet hose
now turn on pump for 30 seconds and then close the bleeder
This should do it
Please remeber to rate this solution
