Whirlpool GU1200XTKQO. New impeller does not fit. The motor shaft has a thread on it and the old impeller had a sleeve with threads to screw impeller on the shaft. The new impeller will not fit over the shaft. The new impeller is threaded but the hole is smaller than the shaft. There is no post that addresses this.

I too am having the same problem with my GE dishwasher- everyone insists its the right part-even matchs the old part number, but doesnt fit- did the manufacturers change these parts so we cant repair and have to repurchase ??

Here's the part given for your model number. Is this the one you received? If so, perhaps it's necessary to replace the entire assembly.

Part number: AP3738238

Part number: AP4434021

What is your model number?

Thanx for the inquiry My model # GSS1800H00BB. Its the right part number on the part- old and new- it just doesnt fit over the seal assembly as the plastic sheath that goes over the motor shaft is up to high and doesnt allow the impeller to seat properly- the old one- or whats left of it had a larger hole in the center to allow it to seat. The new one is causing the drain cover to sit too high and water just spins back into the washer. Can I adjust the seal ?? The collar on the new impeller fits the motor shaft. the only minor difference is on the GE part is a number off to the right is 4 on the new and 1 on the old. I will post GE part numbers when I get home.

anyone ???

I would contact GE and ask for information about the patr change. It looks like you might need to replace the entire pump assembly.

GE Genuine Part #WD19X10029 lower impeller appliance pro part AP2618361 for Model GE GSS1800H00BB. I called GE and they said this is the part and NO modifications have been made "Sir, this is the part that came with your dishwasher when you bought it new". I have attached pics of the issue. I cant seem to slide the plasic collar that is on top of the spring (screwdriver pointing to) down and dont want to force it. GE claims the seal assemble is the same as the one it came with and there are no changes to these parts. I am obviousely missing something here- I consider myself a decent handyman/repair person- not an expert- but I have replaced the water inlet valve on this dishwasher and repaired other appliances including my stove , dryer & washing machine.
As you can see the new part sits too high and won't allow the drain cover to seat flush. Checked motor function, drain line etc..and all fine. This is a reversable motor draining system.

Anything will help at thi spoint. Don't want to spend $50 on seal assembly to find its the same issue.
