I am having difficulty removing the impeller on my BaquaPure 2.0 Horse Power pool pump

The impeller on this Hayward pump unthreads counter clockwise.
Take a big flat head screw driver and put it on the center shaft on the back of the motor to hold the shaft solid while you unthread the impeller.

Hi,
ICE is potential freeze condition warning. Should not relate to the pump issue.
Is your new motor same Amperage as old one?
Is the wet end(pump) on the new pump the same horse power as the one it replaced?
Lack of ventilation for the motor, or clogged motor vents.
Check for undersized wiring or poor electrical connections.
Check if your pump has a thermal overload, this safety mechanism will turn the motor off when it gets too hot. The pump should restart once it cools down.
Remove the intake plumbing and visually inspect the impeller, observe for impeller failure. Spin the impeller to see if it turns without impedance.

Before you inspect the pump turn of the power to avoid electrical shock!

I don't know the answer to this ... your pool service company can advise you. To my way of thinking, you are asking a lot of a 3/4 horse. I have a 1 1/2 horse lifting water in a two inch pipe about 4 feet to my water feature with no reservoir.

Since you have a two inch pipe, why not run a bigger motor? I have two HP on all my filtered lines which are 2" suction and 2" discharge.

Are you absolutely sure you have suction? ... and no air leaks on the suction side?

If your pool pump is acting sluggish it may simply be a build up of debris inside the impeller. Cleaning it is simple if you know how.
Step 1 - Check the Impeller

You can check the impeller for clogs by opening the clear cover that is on the strainer basket. Then place your garden hose into the basket and turn it on high. The water should disappear immediately. If it does not, you may have a clog.
Step 2 - Turn off the Power to the Pump

Before actually removing the clog from your pool pump impeller you will need to turn off the power to it. Remove the basket and use a finger to reach into the hole behind the basket to feel for any debris. If it is clogged, go to step 3.
Step 3 - Disconnect the Pump and Motor

Disconnect the pump and motor from the plumbing. Depending upon the make and model of your pool pump you may be able to skip this step. The motor usually just slides away from the pump.
Step 4 - Remove the Plastic Cover

Take the pump apart by removing the plastic cover over the motor. This cover generally has several small screws holding it on.
Step 5 - Remove and Clean the Impeller

Once the cover is removed you will easily be able to see the clog in the pool pump impeller. Just use your fingers or a coat hanger to clean it out.
Step 6 - Clean

Put everything back together. Once you have it cleaned out you can put the cover back on and put it all back together. Problem solved.

For an impeller really stuck on the motor shaft you need to pull the motor thru-bolts and remove the rotor with the pump still attached from the stator. Lock the rotor in a vice and turn the impeller off with a large set of channel locks or a large strap wrench.

the impellers only usually get damaged with extreme cavitation. You most likely have a clogged impeller. It sometimes happens when the pump basked is cracked or damaged and it lets debris through to the impeller. You may have to remove the bolts and separate the seal plate from the wet end to access/inspect the impeller.

Remove the back of the motor ... you will find there are flats on the shaft. Put your 7/16 or 1/2 open end wrench there and with your other hand, spin off the broken impeller.

I believe the jacuzzi pump impeller has a locking screw directly in the middle of the impeller. You'll have to turn it clockwise to remove it. Then you'll need to remove the cover from the back of the motor using a 1/4" nut driver. Depending on the motor, you should be able to use a 7/16" open end wrench to hold the motor shaft from turning as you turn the impeller counter-clockwise to remove it. Some motors are different, some have a keyed shaft or require a special tool to hold the shaft while the impeller is removed. Hope this helps.

Once you have the housing apart, 6 screws/nuts I believe, make sure you have the power completely shut off at the breaker. Remove the rear housing on the motor to expose the armature (shaft). Depending on the motor, you will need a 7/16" open end wrench to hold the shaft, be careful not to damage any components, you may have to remove the capacitor or switch to access the shaft. Once the shaft is being held, try to remove the impeller by turning counter-clockwise facing the impeller. If it will not move, you may have to use an impeller removal tool. Most pool supply places have them. Be sure to install a new shaft seal, its best to replace the seal anytime you mess with the impeller. Having a good shaft seal will save your motor bearings.

This video helps, although its not the same pump..

I hope this helps....
