Questions & Answers

For Whirlpool Dishwasher Impeller & Seal Kit (Part Number: OEM18144990)

1 Answer

Hello Dave, To remove the motor from the sump housing you will want to remove the securing bolt securing the wash motor and drip shield in place on the pump assembly. Once removed turn motor approximately 1/4 turn until it stops. Pull motor straight back from the sump. This may take some effort to dislodge. The volute will remain attached. Keep in mind when reinstalling the wash motor and the volute, do not pinch the volute seal between teh volute and sump. Use a small amount of rinse aid on the volute seal to help installation. Once pump is off you can remove the impeller and volute. To remove the impeller, slide a flat blade screwdriver into the back of the wash motor to keep armature of motor from turning while unscrewing the impeller clockwise. Take care not to scratch or nick the motor winding. Unscrew the impeller then line the arrow of the volute up with the triangle mark on the pump and lift off volute. Reinstall in reverse.

Hello Anthony, If you replace the impeller, you should order new "O" rings to eliminate the possibility of a water leak.I personally would not fool around with it. I would replace the pump and motor assembly W10782773. The only disadvantage to this is the expense. The headache of getting it all back together and finding that you have created a leak, is not worth it at all.

Jsmith8918 for Model Number GU2500XTPQ7

Our Whirlpool Gold Quiet Partner III started making some grinding noise a few weeks ago. The dishes were still getting cleaned, but ugh, that grinding noise! I pulled the dishwasher all the way out and put it on its side and took out the motor from the bottom and the spinning cutter from the inside of the tub and cleaned everything out and put it all back together. There was quite a bit of debris inside the tub at the cutter location, but the motor and impeller looked rather fine. All seemed to be well for a short while, but then the noise came back on a smaller scale. But then, all of a sudden, the dishwasher is quiet... too quiet... and even the easiest-to-clean dishes were seemingly untouched. I discovered that the water spray from the bottom sprayer was only spraying up about half the height of a normal dinner plate and moving very slowly. Suggestions? Ideas? Parts you'd recommend first?

Hello Cg. Check and see if the water is filling up close to the bottom of the heater assembly. If not, replace the water valve. Also, check and make sure the filters inside the unit are clean and clear from debris. Hope this helps.

Jeff for Model Number GU1200XTKQO

I have a whirlpool GU1200XTKQO. This is the brand and model number. I ordered an impeller and received it from APP. It is not the correct part. The motor shaft has threads and the old impeller threaded onto the motor shaft. The new impeller sent by APP cannot do this. I need help locating the correct part. The parts people say part #8193951, which I received is the correct part and they said the notes say, "this part threads on" but that is incorrect in relationship to the part I received.

1 Answer

Hello Jeff. Based on the model number, 8193951A is the correct impeller. Make sure there is none of the old part stuck on the motor shaft. Here are the instructions from the manufacture on replacing the impeller. Hope this helps. Place the end of a flat-bladed screwdriver into the back of the wash motor to hold the armature of the motor from turing while unscrewing the impeller clockwise. Take care not to scratch or nick the motor windings. Re-install in reverse order.

Chuck, Most often noise issue with a dishwasher is a small, hard, article has enterred the pump or drain impeller area, and is bouncing around in the chamber, causing the noise. Once you remove the accumulator and inlet cover, you can carefully clear any debris from the chamber. Thanks and Good Luck

Hello Todd. The service manual for the model number you provided has been discontinued. The impeller 8193951A unscrews from the shaft of the motor. Turn it counterclockwise. Hope this helps.

Hello Kenkneed. Yes, if the shaft needs to be replaced, you will need to replace the motor assembly WPW10757217. You will need to uninstall the dishwasher to access and replace the motor assembly under the bottom of the unit. Hope this helps.

Kenkneeb for Model Number KUDS01DJSW0

Hi: I've replaced the Chopper Assy for our KUDS01DJSW0, seated it in the groove in the housing, replaced all the parts, and ran the machine only to be greeted by 'that grinding sound". I removed all parts and analyzed the problem to surmise that the impeller shaft teeth appear quite worn and in need of replacement. Please help me understand if (and if so how) I can replace just the impeller assy. for our model, or do I have do an entire pump assy replacement. I can't see any way into the dishwasher's pump assy from the inside of the unit. Thanks for your prompt anddetailed response as our dishwasher is now out of commission sitting lonely waiting for our TLC!
