Pump was working fine yesterday popped the breaker

FLO stands for flow switch open. If the pump is running and you have water flow it may be that the flow switch is not working properly. If your pump is not pumping water then you may have an air lock in the system.

if you had ice in it and it was powererd up.. you may have burned out the start capacitor or even the start windings..why was it iced up while working on it..it should have been freewheeled by hand before startup..I just got a tub in here.. had to wait 6 days for it to thaw out..(sign of good insulation) we just ran it for the first time yesterday..got some seals to replace and some switches to repair..

Is the shut off occuring @ the GFI? & is there an error code displayed on your topside?

If the breaker is kicking off, the best way to troubleshoot is to disconnect all components, (pumps, heater, circ, etc.) & then plug one in & turn the breaker on. repeat the process until you locate which component is tripping the breaker.. then you know whats causing the trouble

if pops breaker need new pump motor if it doesnt pop breaker check voltage at pumpmotor if voltage bad motor

You shorted the 230 lines at the motor terminal board. If you are certain you have reset any and all breakers feeding the spa and that the 230V is getting back to the pump motor then you blew the winding leads as you shorted the motor. While it is possible a motor shop could repair the leads it is far more likely the damage caused will cause the price to be that or more of a replacement motor.

Sorry, sounds like it's shorted out. Time to replace the motor

The motor may have blown the start capacitor. It is the black cylinder about 1-1/2" dia x 2-1/2" long. Look at the end with the wires for a small hole. Is it blackened or have a hole blown thru? If so replace it. Otherwise have a local electric motor repair shop look at it for possible repair or replacement.

You may have a leak that is shorting out the circuit. Make sure there is no water in the vicinity of the motor (other than in the pipes obviously). If there isn't any water on the motor, check to see what else is on the same circuit. This can be done with a lamp. When it pops the circuit next time, check other outlets to see what else has lost power. It could be the wife inside making a margarita for you. :-)

Pump seal is in two pieces. The piece with the spring should be easy to remove. To remove the piece that is inside the motor side of the pump housing, place the housing with the side that should be facing the motor downdwards on a flat surface. The hole in the housing is larger than the seal, so use a screwdriver and, placing first on one side of the seal and then the other, strive the handle of the screwdriver sharply and the seal should pop out the bottom. The seal is rubber, with a ceramic insert, so if you don't tap the screwdriver too sharply the insert won't be damaged. In any case, it's a good idea to replace the entire seal if you have had to open the pump and remove the impeller

does the breaker pop with an empty tank?
if so then you need to see if the unit turns free,try running the m/c disconnected from the pump unit,my guess is that your drive motor bearings or internal windings are at fault
hope this helps regards ian
