How to Troubleshoot & Replace Lg AP4436601 / 4738ER2002A Vent Hose

I originally thought the washer had a bad bearing, but once I got it disassembled it the spider arms were broken. This required the replacement of the tub assembly. While replacing the tub I replaced all of the water bellows. The parts came quickly, the live chat and videos were very helpful. This washer has to be completely disassembled to replace the drum, so mark all the screw locations, tag and bag everything and take lots of pics. It was a very rewarding project and hundreds of dollars cheaper than a service call 

Based on info around the web and your site I chose to replace all of the bellowed hoses (3) in the machine, as I did not know which bellow was leaking without taking the washer apart first. If one hose was old enough to leak I figured the others were not far behind. The appliance parts pros videos were very helpful, although I chose to replace the drum drain bellows via access through the rear panel thereby saving myself the time of disassembling the front of the machine, as was instructed. In the end none of these hoses were my problem, but I replaced them anyway and learned a lot more about how the machine functions in the process. The culprit was an intermittent supply hose valve on our wall behind the washer. Occasionally it would leak, spraying the bottom rear of the machine, leaving a puddle running out underneath the front. Replacing those solved the problem and I'm confident that I won't have any leaks stemming from hoses inside the machine. I also took the time clean the mold that was accumulating in hidden portions of the soap tray. I used a HE tub cleaner (Tide) and ran it through a number of cycles to rid the machine of internal mold & scale not visible inside the drum. 

I started by watching the video and it was very helpful. I would make one suggestion. On our model the weights on the tub sit very close to the front gasket. It is much easier to put the gasket on the tub before you put the weights on. Also, since the washer was tore apart, I replaced the hoses and seals and shocks since the machine is about 8 years old. The shocks made a huge difference. It spins like it did when it was new. Thanks for the video, it was very helpful. 

I opened the lid and replaced the hot water inlet valve assembly. Checked all the rubber hoses were clamped tightly and closed it up. As a precaution I laid the washing machine on its side. I replaced the tub to pump hose as well. Once finished I put the washing machine on cinder blocks so I could see where the leaks were coming from. I put 4 laundry loads in and not one leak!!! I am glad I did not call for a repairman. 

Handy friend located source of leak and identified the part in your catalog 

Followed the video and replaced the hose. Easier than I thought. 

Replaced top Bellow and solenoid 

I was going to have an Appliance repair guy fix it. I removed the top for him. Then I thought I am going to turn this on and see where it was leaking. It was right in front of me. I saw the parts, and I realized I could do this. Went to Appliancepart Pros and ordered the parts. Being in California I thought the parts would take a while to be delivered. Ordered on Sunday night and by Tuesday by noon I had the machine working again Easy, Easy, Easy!!!!!! Saved at least $150-$200. For something a monkey could do. I know this because I am that monkey. 

I replaced the water inlet valve assembly. It appeared this is where the water was dripping from while the machine was running. It did not take long to diagnose the problem. With the top of the washer off I could see the water accumulate and drip. It didn't seem to be enough to cause the leak we were seeing, but replacing this part has stopped the issue. The part was simple to remove and replace. I (a woman) was able to do it completely on my own in less than 20 minutes. I also replaced the vent bellow because I noticed a small crack in it. Simple repair as well! 

Ordered new pipe from appliancepartspros.com. Order came very fast and cust svc on the phone was excellent.Will go to them 1st if appliance parts needed. Great experience!
