My Jandy Aqualink RS8 turns on then off immediately

Motor turns on for second then the circuit breaker flips off.

This is the first time you told us the CB has been tripping.

You have been saying the “motor stopped” as though it was a motor problem with the power on.

Turns off and CB tripping are two very different problem descriptions.

Great catch. May have damaged both new motors.

Motor looks like it’s selected for 115v operation. Ensure selector (arrow) is pointing to 230v.
Pic of “Filter” circuit looks like 2-pole so, it’s has to be 240v.

I set the jumper on pool motor to 230V and that fixed it!!

I'm surprised my old Century B230SE (same part number as 2 new ones Century B230SE) jumper was set to 110V for years and was working fine.
