Questions & Answers

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

Mark W for Model Number GU2200XTSq3

My dishwasher is now much louder than normal when the recirculation pump operates. The pump is still pushing water (i.e. the dishes get wet), and the sound isn't awful, but there's definitely something different going on. I took things apart from inside, there's nothing stuck in the chopper and it turns without binding. I'm now thinking I either have a problem with the impeller or a bearing problem with the motor. 1) Is it possible to inspect the impeller from inside the machine? I couldn't see much when looking into the discharge port from the top, but I didn't try a mirror. 2) Is there another way to know which part needs replacing? 3) Any other suggestions on what the noise might be? 4) While I wait for parts, is there any reason not to run the machine? I suppose if the problem is an impeller I shouldn't run the machine and risk ruining the motor, but if it is a motor bearing I'll need to replace the motor anyway, so I might as get a few more last days out of the thing. BTW, thanks very much for the >excellent< video on replacing the circulation motor. Super! (link: http://www.appliancepartspros.com/whirlpool-circulation-motor-w10239404-ap4434021.html#autoplay ) Thanks for any assistance. Mark

Hello Mark. No, to inspect the impeller, you must remove the motor from the unit.

Hello JR. 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 the 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.

Randy, the issue would be the electronic control WPW10084142 . there are only two components involved, the drain pump which works and the control board. The eeprom on the control board most likely has a "glitch" and gets stuck in the drain increment circuit.

Kashif S. for Model Number KUDS02SS Kitchen Aid Dishwasher

I have a problem with the dishwasher. After finishing the cycle, some dirty water stays at the bottom. Couple of weeks before I cleaned opened up the bottom area and did some cleanup as much as possible. There were indeed few things stuck there and impending the flow of water. After that, water still remained there but sometime less sometimes more (but doesn't overflow) and was relatively clean looking. Now its starting to become dirty again. I am wondering what could be wrong, before I start opening it again? Any insight is appreciated.

Ted, there may be glass in the impeller jamming the assembly, or possibly the glass shards have damaged the vanes on the impeller 8193951A . You'll need to remove the motor pump assembly and remove the volute and motor and check the impeller and the chamber for debris and blockage.

Hello Kenneth. No, it is best to remove the motor assembly to install the seal properly into the unit. It can be done, but may not seal good and leak.

Kathy, Yes it could be the chopper that is the issue. You will want to pull the pump apart and make sure that everything is back together properly and make sure that any screws are tight.

Hello Larry. You must remove the motor to replace this part. The impeller unscrews off the motor shaft of the unit. You need to hold the motor from turning when unscrewing the impeller. Usually it is easier to replace the motor assembly... more instead of just the impeller

Storm77 for Model Number kudp01ilbs1

Hi I've determined that my impeller is not engaging with my chopper assembly. From reading the posts and responses on this it looks like something is in the assembly or I need to replace the impeller. However I've not been able to find any instructions to replace the impeller alone. All the instructions ask me to replace the entire assembly. Ideally I'd like to figure out if there's a way to tell if there's some gunk in it that I can clean out first. Thanks
