That click you hear is the pump's breaker, or thermal overload kicking in. After about one minute, the pump has cooled down again.

I believe this type of pump is not self-priming, and therefore, it needs to be primed and purged of air. If it is not a self priming pump, there should be a small plug on top of the pump housing. Remove the plug, and add water from the top opening until the water overflows, and then replace the plug. Or, if when you remove the plug, water comes out the top opening, let it flow for a few seconds, and then replace the plug.Then, turn the pump on.
Hope this was helpful...

Are there any other booster pumps that I can use to run my pool cleaner? I had a Polaris bp4-60 for 7 years, it finally failed. Replaced it with same model. Ran for few mins then shuts off then restarts....

I think Polaris should refund the purchase price on these pumps. I changed the breaker, the whip, and upgraded the outlet (using 110). The dealer exchanged it for me, but would not give me a refund, and I had the same issue with the second motor. I used a Hayward 6060 pump as a replacement. Everything works fine.

I have a Polaris PB4-60 booster pump, less than 3yrs old. I turned the pump and left. When I got back 1hr later, the pump was not running. Breakers had been tripped. Each time we reset the breakers and...

If the device that tripped is a ground fault circuit interupter (GFCI) breaker or receptacle then it is likely caused by 5mA or more of leakage current to ground within the motor. If what tripped is a circuit breaker then there are likely shorted turns within the motor. Usually either of this issues requires a new motor.

If you are not wanting to turn wrenches yourselfthen my best suggestion is to bring it to Leslies Pool Supplies and they oftencan put it right for the price of the parts while you watch (they might not have some parts in stock).

I hope this helps.

Installed a new 3/4 hp Polaris pool sweep pump.

Check your voltage and be sure it matches the way the motor is wired. You will find a scematic for this on top or on the side of the new motor, with a diagram on how to rewire it if nessary. If this is not the problem then it is in the motor and should be returned for a new one.

When it's running for about a minute, is it pumping water?
Is this a self priming pump or do you need to prime it?

POLARIS PB-4 3/4 HP BOOSTER PUMP -- body of pump very hot, too hot to hold hand on. 20 amp breaker gets very hot also. Has not tripped the 20 amp breaker yet.

A motor can run that hot and still be within the temperature it can handle. It likely has an internal overload device that will shut it off if it exceeds that temperature. If you see something like "thermally protected" on the motor nameplate, you are ok. If it is getting noisy as it runs it may need servicing.
