New century 2hp will not come on

I am having issues with my pump. My first pump (ecotech VS) went bad while trying to refill DE into my pool, which was just refilled after a pressure wash. It showed "high amps" on the display and there was a pop and it won't turn back , just a flashing green light.

I purchased a 2hp century motor off amazon to replace it. We hook up new motor, two hot wires to L1 and L2 and the ground and pump will not come on. My panel is a mess and i have had no luck in finding a similar panel to replace it. It is rusted and wires are all over the place, hence it is confusing.

The pump for the waterfall was working fine and we have been using it to try to circulate chemicals to stop pool from turning green. But today, the pump just hums and won't come. Not sure if this is directly related to the issue with the other pump.

We took the power and ground from the waterfall pump and put it on the pool pump and it did not come on. We also took the power and ground from the pool pump and connected to the water pump and it did not come on. I am now at ends wit on what else to do. I have my nephews and nieces coming to visit for 2weeks and they really wanted to get in the pool. Any help is appreciated. I attached a pic of the panel

Ok,

With the meter set to Volts AC measure the pump input between L1 and L2.. If you have about 240 VAC, then the pump should be running, so the pump has to be bad.. If you don't have 240 VAC, that is why the pump is not running.. Keep in mind that you must measure between L1 and L2.. You can't measure between L1 and ground and L2 and ground as this can give you an incorrect reading..

If no voltage is getting to the pump, you need to follow the circuit back to what tells the pump to run.. Most likely a relay called the Pump/Filter relay. Measure the output of the relay, between the two output pins.. L1 and L2.. If you have 240 VAC there, then the wires between the relay and the pump have an issue.. If you have no voltage on the output of the relay, check the two input pins.. If you have voltage on the input pins but not on the output pins, then the relay is not being turned on, or the relay is bad..

If you have no voltage on the relay's input pins, then you need to follow the circuit back to whatever feeds the relay, most likely a circuit breaker.. Do the same thing again.. Measure the circuit breaker's output (between L1 and L2) and see what voltage you have. If you have no voltage out of the circuit breaker, then the breaker is popped, bad, or no power is being applied to the automation panel..

See what you can find out by testing in an orderly logical process rather than connecting a bunch of stuff together and hoping and praying.. :poke:

Thanks,

Jim R.

Thanks so much. Found the issue, one of the terminals, L2 was disconnected on the inside of the pump. Will be returning as i ordered and received a replacement.

New problem now, after hooking up new pump, it gets power but keeps leaking water between the diffuser and pump
