Pool isn’t even 1 year old. Called in a noisy Aqualink transformer to the builder, and they said they wanted to send a PM out first before calling in the warranty part. He came out yesterday. Opened up the panel and he started poking around. Everything out there turned off, no lights on the Aqualink panel. He left and said he’d call it in since the pool was basically dead. Once he left, I opened up the panel and noticed the 3.15amp fuse was blown. Ordered replacements that got here this morning, popped a new one in, panel turned back on and now I have lights at the panel, but the pump won’t turn on. Shows it’s in pool mode now.

Checked the transformer with my multimeter, and I’m getting 26 volts. Pulled the access panel off the back of the pump and with the non-contact volt meter, I got beeps so it should be getting power. I’m able to turn the pool lights on and off via the Aqualink app, so it would appear that all is well there. Unsure of what I can try next to see if I can get the pump running again. Let me know what else is needed and I can add whatever details from here.

All of this is powered from the main electrical panel on the side of the house, that goes to a sub panel out at the pool. I’ve turned the “filter pump” on and off several times just to see if that would do anything, and nothing different happens.

Do you have power at the pump itself? Is the RS485 (red) connector at the Jandy panel still in place or any of the wires come loose?
 
I double checked the RS-485 (the one on the right goes to the pump) and everything appears to be tight. I used a non contact volt meter on the input side of the pump, and it tells me it has power.

A non-contact tester tells you there is some voltage in the lines but not how much nor where. Rub it quickly with your fingers or across your pants and it will register voltage. You always need to do something like that to determine if the tester is even working before testing for voltage or you may be in for a nasty surprise. You need to know if there is 240V across the terminals.
 
Interesting, I had no idea it would register voltage that way! This is what I get at the pump.

Checking it again, I get 125 on L1 to G and 125 on L2 to G

You need to test voltage between L1 and L2. Should be around 240. Checking to ground can be misleading is one leg is dead.

For whatever reason, I couldn’t get that to register. That’s the photo of the multimeter showing 2.89.

That indicates one of the legs of the circuit breakers is dead.

Reset the circuit breaker. If you still do not get voltage at the pump, replace the circuit breaker.

You can confirm by checking the voltage at the CB contacts if you are comfortable working on a panel with live voltage

You only have power coming from one side of the breaker, or a broken wire somewhere.
Reset the breaker that powers the pump. Be sure that both sides of the breaker go firmly into the off position and then into the on. Use two fingers on the levers so that you feel the same on both.

You might want to also check the 240v breaker that powers the Pool subpanel. That breaker could also have one pole tripped.

If the Bar-B-Q and Pool Light have power then both sides of the bus have power.
 
Replaced the 50amp breaker, back in business. Appreciate all the replies and help here. Now I guess I need to figure out why one side of that breaker is burned up?
