Lg 4370ED3006A Upper Spray Arm Pivot Shaft OEM Part

I replaced the upper nozzle guide, nozzle shaft and upper spray arm. I also replaced the pump gasket for good measure. Top rack dishes had not been cleaning properly. I first removed the filter assembly to inspect the main pump from above. It was clogged but after cleaning and reassembly I observed that while middle and bottom spray arms were changing position, the upper spray arm was not. I confirmed that water was flowing through the upper spray arm by placing some empty yogurt pots on a baking tray on the top rack. The ones underneath the spray arm filled up. I tried cleaning the spray arm by removing it and flushing it with water but that didn't help. When spinning the upper arm by hand it tended to stop after a few turns so I wondered if the shaft had worn down and was creating too much friction for the nozzle to turn. So I ordered replacement upper nozzle guide, shaft and spray arm and tried them out. On the same order, I took the opportunity to replace the filter assembly (still a little clogged), the pump gasket (showing signs of wear) and some broken dish rack rollers. After replacing all those parts, the upper spray arm was back to working order.

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.

Replaced nozzle shaft.
