When the pump is plugged in the heater an jets run the jets won't turn off

SOURCE: jet pump will not shutt off

it sounds like the pump relay may be stuck closed. Also check the temp readout, if it thinks the water is too hot it will try to cool the water by running the jets and sometimes the blower as well.

Thank you for posting your question here on Fixya.com.

Start with the pump. If it is bound up and not starting nothing else will work. Close off your valves and disconnect the pump unions. Once free, reach in with the pump unplugged and try to turn the impeller by hand. Will it turn? If not, you'll need to free it or get the pump repaired. Once the pump is working and water circulating your heater should start working.

SOURCE: i shut off my pump

I suspect you had air trapped in the filter. When the pump shut down, the compressed air in the filter pushed back, turned the pump backwards, and unscrewed the impeller off the motor shaft. This particular pump doesn't use an impeller screw which prevents this from happening. You will have to pull the pump apart to see if this is the cause. I have seen this happen many times.
