How to Troubleshoot & Replace Lg AP6800730 / AGZ72909711 Pulsator Assembly

We had a repair man come and tell us the needed repair at the cost of 70.00 I ordered the parts and saved money. 

Put new Pulsator Assembly on the washing machine Shaft.Ratchet and 10 mm socket is all it takes. 

Plastic gear in agitator was worn. Note that this plastic part is typically hidden by a metal insert that converts the diameter of the shaft gear to the diameter of the agitator (pulsator). If you can spin the agitator freely, check here first before concerning yourself with the actual motor/gearing under the unit. All you need for this repair is a flat blade screw driver to pop the cap off, and a 10mm socket to pull the agitator (pulsator). My cap broke so I replaced it, but you might have better luck getting yours off and only need the agitator/pulsator. 

I was able to watch the repair videos on the website and replicate the steps on my washing machine. The videos highlighted the problems that I would face before doing the repair, it saved a lot of time and frustration knowing the tricks ahead of doing the repair. 

I ordered the new Pulsator Assembly and bolted it in using a 10mm socket. 

A waxy brown scrud residue had built up on the outside of the washer drum and bottom of drum "pulsator assembly." Running the cleaning cycle was not effective to remove all of the flakes. I had to remove the drum and pulsator assembly and scrub clean using a large brush, toothbrush and hot soapy water. After reassembling the washer, the problem continued because the scrud was also on the inside of the pulsator assembly, which is a sealed unit. I purchased a new pulsator assembly and pulsator cap to fix the problem. A new pulsator cap was necessary because I damaged the original part removing it from the washer, the plastic tabs had broken off. Once these parts were installed, the problem of waxy brown flakes was solved. 

I called you all and I spoke with Robin who is fantastic! She helped troubleshoot and we figured out the inside of the agitator where the grooves are were stripped out. So she found one that matched my machine and I received it in the mail the next day. Robin was so nice and patient and knew what she was talking about, I highly recommend her and Robin, I again thank you for all your help! Ashley C. 

It needed a new agitator and AppliancePartsPros had the best price. The parts came quickly and my son-in-law was able to install it in about 10 minutes. Highly recommend this company for any parts you need. 

I found that the Pulsator/Agitator plate on the bottom of the washer would spin freely with no resistance. I remove the plate and found that my splines were worn. But not worn out. The insert that the splines were made into. Would spin in the plastic that was holding it. It would act just like stripped splines that apparently, is common with these units. I found and ordered the plate from AppliancePartsPros since they showed the fastest delivery time. It was here in 2 days. Took about 5 minutes to put everything back together. Now it works as it should. Thanks to APP for all their help. 

I replaced the pulsator actuator plate. I was lucky it was not corroded and installed it with relative ease. Machine now agitates. Flathead screwdriver and 10mm socket and flashlight
