How to Troubleshoot & Replace Lg AP4997094 / 4370ED3006A Upper Spray Arm Pivot Shaft

Replaced defective filter with new part from APP. Watched the on line video and made replacement following the instructions. Customer service was very helpful and shipping and packing of the parts was very good. Highly recommend company. 

It was a simple repair that required ordering a Nozzle Shaft. While doing the repair I thought my nozzle assembly was probably gunked up inside so I replaced that at the same time. Simple repair but make sure the nozzle shaft is perfectly aligned and centered before pushing it in. 

I called a repairman out ($90) to diagnose problem which I was unable to figure out on my own (after tearing apart dishwasher). It was a simple $1 washer that was rotten. While I was on this website I went ahead and ordered some other gaskets too. 

I had to disassemble the circulating pump housing to replace the motor. The cam motor shaft seal had failed. This led to water leaking to the motor which caused it to rust. After replacing, my dishwasher went back to being silent. The hardest part was figuring out how to access a couple of screws on the housing. 

Replaced nozzle shaft.
