how much amps the pump motor is drawing at start up and then while running

The impeller has a reverse thread locking screw through the center. You can secure the motor shaft by putting a 9/16 open end wrench on the other end of the shaft, which is under a cap in the middle of the rear of the motor.
Check your seal plate carefully. Whisperflo is a great pump but they don't take heat very well. It is very common for the seal plate to also be damaged when the pump runs hot, particularly the lower inserts where the bolts screw into.

The noise is likely either the seal or a bearing in that order. If you are mechanically capable of working on the pump yourself then you can purchase a seal and gaskets at a pool supply store. If the bearings are bad then the motor needs to be replaced. In some cases a bearing can be replaced but usually it is more work than it is worth.

You are probably wondering how to remove the impeller - generally, these are screwed on to tha motor shaft - motors normally run clockwise when viewed from the rear, so thread is normal right hand. remove fan cowl and fan from motor in order to be able to restrain the shaft while you unscrew the impeller - it should be straightforward from there.

Bearing failure is more often than not brought on by leakaege from the mechanical seal - when you reassemble the pump you should replace the seal assembl - also make sure that there is no damage in the form of melted plastic around the seal stationary seat area; replace parts as necessary.

Yes the impeller is screwed on right handed normal thread. *** Info below pasted form one of my other posts *** You need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, (usually 9/16") or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. (you already did this.) It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it.

Disconnect all power. Remove the six bolts holding the seal plate to the wet end. Remove the two small allen screws to remove the diffuser. Remove the dust cap from the end of the motor and secure the shaft from moving. If installed, remove the Phillips head screw in the center of the impeller by turning clockwise (left hand threads). You can now remove the impeller by turning counter clockwise, note that you may need an impeller wrench to remove it and a specific tool to hold the shaft while you remove the impeller. Once the impeller is off you can remove the four bolts that hold the motor to the seal plate. This process just needs to be reversed to re-install but you will need a new shaft seal (PS-1000).

Turn off the valve that supplies water to the basket just before you turn off the pump, then the leaves can't be sucked back up. There are normally valves on both sides.

Check the power cord for damaged wires. Check for a faulty breaker. Check power going up to the unit...If power stays on up to the unit then you have a short inside the unit someplace.

The pump is running at prime speed at start-up. Your highest speed (number on panel) might be much lower than prime.
Try setting the rpm for the speed number you select a bit higher. You will need to know how to adjust and lock in the rpm you want.

After 30 minutes of use, feel the outside of the breaker that is tripping. If you feel heat on the surface of the breaker it could be the breaker is going bad. Have an electrician change the breaker and have him check the load on the breaker. My guess is, if the heat pump seems to runs fine for an hour but is tripping a breaker then it is probably not the heat pump.
