Winding noise with some water leaking from the motor seal. Water still flowing but sounds laborous.


The shaft seal more likely than not needs to be replaced. If your shaft seal has been leaking for any length of time, the bearings could be damaged and this should be replaced. The whisperflow uses a PS1000 shaft seal and is fairly easy to replace (most seals available online or at most swimming pool retail stores). It is best advised not to run the pump until you have had this inspected by a licensed pool technician or have changed out the seal.

1) Make sure breaker/power to pump is off. 2) Remove the six bolts holding the wet end to the seal plate. 3) Remove the diffuser to expose the impeller. 4) Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 5) Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. 6) Once the impeller is off, remove the four bolts holding the seal plate to the motor. 7) Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. 8) Apply a thin coat of lube (I prefer Magic Lube or Lube Tube) to the seal plate and impeller where the new seal will go. 9) Remove the new PS1000 shaft seal from the box (being careful *NOT* to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. 10) You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. 11) Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. 12) Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.
Check the pump for operation and you should be good to go!

How do you remove the empellor from the motor shaft? The seal is leaking. I have the 4 screws loose holding the pump casing. Does is slip off the motor shaft or is it threaded on?


First off, are you sure it's the shaft seal leaking and not the Valute (the large o-ring or seal that is in between to two halves of the pump) seal? To clarify, if you get your head down and look at the bottom of the pump while it's running you should be able to see the water coming from the joint between the seal plate, and the seal plate housing, or just behind that from the bottom of the motor probably from the vent holes in the motor housing.

Now to answer your question, assuming it is the shaft seal leaking.... You may have already done some of these steps, if so, sorry - just ignore, but it may help others. To get to the impeller, you need to split the pump into two (the wet end from the dry end) This is done by either removing a large clamp, or removing 4 to 6 bolts depending on the pump. (I'm not talking about the 4 bolts that hold the motor to the seal plate, those come later see below) Once you do this the Motor, seal plate, impeller and diffuser will all pull back away from the front of the pump. At this point it's best to disconnect the electric and remove the whole assembly so you can work on a table or bench. Before removing the impeller you need to remove the diffuser which is screwed over the impeller onto the seal plate with 3-6 small screws. To remove the impeller you need to lock the motor and just unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, 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. 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. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. One thing to note and/or clarify... in your description you said you have the "4" screws loose... As I mentioned above, most pumps have either a large clamp or 6 bolts holding the two halves of the pump together. In your case I believe it's bolts. Some have 4, but most have 6. Then there also 4 bolts that hold the motor to the seal plate. Just want to clarify that you split the pump in two and remove the diffuser, and impeller, before removing the motor from the seal plate. I haven't worked on a Waterway in awhile, but there are basically the same as many other pumps. You may have 4 bolts, just wanted to clarify from the motor mounting bolts. If something looks different on your pump from my description let me know by leaving a comment and I'll clarify asap. Good Luck!

How do you replace a seal on a Sta-Rite pool pump? How do you remove the old seal? Ceramic and graphite.


Replacing a shaft seal requires some good mechanical ability.
first, always make sure power is off at the breaker before you work.
You'll have to remove the band holding the wet end to the seal plate. Then remove the diffuser covering the impeller. Remove the cover on the back of the motor. You either need a 7/16 open end wrench or a armature tool to hold the motor shaft while you unthread the impeller (if the impeller has a screw in the middle, you will have to remove it by turning clockwise, left hand threads) counterclockwise. You can then pull the carbon part of the seal off of the impeller, make sure to remove all of it including the metal sleeve. You will then have to remove the seal plate and push the ceramic part out from the back. You can then clean and lube the seal plate and install the new ceramic part of the seal, try not to touch the ceramic with your hands if possible. You can then lightly lube the impeller shaft and slide the carbon part of the seal with the carbon facing toward the ceramic as you thread it on. If the seal plate had a copper heat sink, you can either replace it or use a different size seal. (I believe it's a PS-201) Re-install the seal plate, impeller (and screw if applicable) and diffuser. You should now be ready to mate the seal plate to the wet end. Make sure you fill the pump before you try starting it up, especially with a new (dry) seal.

A coin fell into the basket and rolled into the gap at the edge of the wash plate. I took the plate out but the coin was not there. It must have fallen into the larger slots beneath the wash plates. If I...


The coin will not drain out nor be fed back into the tub by the recirculation pump but it will block the filter or eventually block the impeller of the drain pump and break it. You'll then experience a draining problem and need to replace the drain pump.

What you have to do is remove the basket to get the coin out then take the opportunity to clean the filter vanes. The coin is most probably still in the filter.

Tape the lid to the top of the washer then disconnect power to the washer.

The top of the washer is held to the front of the cabinet by two locks located about six-and-a-half inches away from the outer edges of the washer. Use a putty knife blade or similar tool to press and unlock the top locks.

Insert the blade of a putty knife into the seam between the top of the washer and the cabinet at the given distance from the outer edges of the washer. Press the locks then lift the top of the washer.

Remove the impeller (wash plate) cap by inserting the blade of a flat-bladed screwdriver or similar tool into the slot in the impeller cap, and then pry the cap off.

Remove the 7/16" hex-head bolt from the impeller (wash plate), then lift and remove the impeller from the basket.

Pull the recirculation hose off the tub ring by compressing the spring clamp holding it in place. Remove the tub ring by prying and unsnapping its tabs from the tub.

Lift the basket out of the washer to access and clean the filter. Remove the two screws holding the filter to the tub. Take the filter off and clean it.

Reinstall the filter, the basket, and the wash plate. Secure the wash plate with the 7/16" hex-head bolt then snap the impeller cap in.

Put the tub ring in place aligning the tabs then snap the tabs back into position. Reinsert the recirculation hose into the tub ring and secure it with the spring clamp. Push and lock down the top of the washer to the cabinet.


In case the coin is no longer in the tub or in the filter, turn off the water supply to the washer. Disconnect the fill hoses from the rear the washer and remove the end of the drain hose from the laundry tub or stand pipe.

Place padding or cushion on the floor fronting the washer, and then carefully lay the washer on its front panel to access the drain pump at the bottom of the washer.

With the washer facing down and you facing its bottom, the drain pump is on the left while on the right is the recirculation pump. You can actually see the drain hose connected to the drain pump.

Using a pair of pliers, compress the spring clamps holding the drain pump inlet and outlet hoses. Move the clamps away from the pump then remove the hoses.

Remove the three 5/16" hex-head drain pump mounting screws. Open the wire cover on the pump then disconnect the wires from the terminals of the pump, and then remove the pump from the washer.

Check the pump impeller for any debris and clean it. Reinstall the pump after cleaning and secure it with the three 5/16" mounting screws. Reinsert the inlet and outlet hoses then secure it with the spring clamps. Make sure the tab on the outlet hose connector fits into the slot in the outlet hose.

Reconnect the wires to the pump terminals then close the wire cover.

Wash impeller wont rotate on fisher paykel model 603


I suppose you have a double drawer dishwasher and this problem is with one of the drawers.

One cause of the impeller not rotating would be that there is some loose cutlerry lodged between the impeller arm and the base rack. This is easy just remove it.

HOwever, the other option is that the impeller itself is stuck. Try opening the filter base plate and removing the impeller rotor to check if no debris is lying around (usually food scraps).

The instructions to open the filter plate and exposing the impeller is in the user guide. If cleaning does not help then check nothing is stuck in the filter sump and the narrow passage connecting filter sump and the rotor cavity which is preventing the rotor from rotating.

The worst case scenario is the impeller rotor is faulty. You can buy this and replace yourself , ie, if you worked out how to remove it.
Good luck

1hp whisperflow pump, seal change. How?


Make sure breaker/power to pump is off. Remove the six bolts holding the wet end to the seal plate. Remove the diffuser to expose the impeller. Remove the screw in the middle of the impeller by turning clockwise (left hand threads). Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. Once the impeller is off, remove the four bolts holding the seal plate to the motor. Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. Apply a thin coat of lube to the seal plate and impeller where the new seal will go. Remove the new PS1000 shaft seal from the box (being careful not to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.

It is a good idea to replace the tank o-ring when taking to pump apart, but if the o-rings are in good condition, just apply a light coat of lube and reuse them.

This is a general guide for replacing a seal, if you have trouble removing the impeller, you may need an impeller wrench and a tool to hold the motor shaft.

I hope this helps, if you have any specific questions, email me at mail@leisurepoolservice.com

Need instructions on how to replace seals


ok, I will try my best. First, make sure power is off to the pump. Then, remove the six bolts and nuts on the front (wet) end of the pump and expose the impeller. On the back of the motor, you will need to remove the small dust cap in the center. Underneath that dust cap should be the shaft that is slotted. You will need a large screwdriver to hold it from turning as you remove the impeller by turning it counter-clockwise. Once the impeller is off, remove the four bolts holding the seal-plate onto the motor. Once you have the seal plate off, press the old seal out by pushing from behind with a flat tip screwdriver. Once the (ceramic part) seal is out, clean the area where the seal seats very thoroughly and apply some silicone lubricant or even Vaseline to for a nice uniform coat to the area, don't leave any of it dry but don't glob it on either. Next, pull the carbon/spring part of the seal off of the impeller by twisting pulling it at the same time. Make sure all of the seal comes off including the rubber washer/o-ring. Apply a very small amount of lube to the impeller shaft where the new seal will go. Install the new seal onto the impeller, be careful not to touch the carbon face of the seal if you can help it. Slide the seal all the way onto the shaft until it bottoms out. Next, install the ceramic part of the seal into the seal plate, be careful not to touch the ceramic surface. Press it into place using some paper of cardboard from the box the new seal came in. Make sure it seats all the way down, inspect it from the back to make sure the seal is completely seated. Install the seal plate back on and torque the four bolts onto the motor. Thread the impeller onto the shaft until it bottoms out, hold the shaft and tighten the impeller lightly, no need to crank on it, snug is good. Check and lube all your o-rings and install the wet end back onto the seal plate. Reinstall the motor shaft dust cover and you should be back in business. Be sure to fill the pump with water before turning it on. You can usually do this by starting your filter pump first.

We have taken apart the bottom of the dishwasher to be sure no food was clogging the exit. It is clear but the water still willnot drain


HI In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.
