How to Troubleshoot & Replace Lg AP4441934 / 5220FR2008E Water Inlet Valve Assembly (Washer)

I found AppliancePartsPros.com in an internet search and was pleased to find a helpful live chat person available to help answer questions. When my questions became too technical, she offered to email me the service manual. I was very delighted to receive the manual and was able to determine the most likely repair needed. After I ordered both the inlet valve and the drain pump, I watched the repair videos and was happy to see that the repairs were not that difficult and could be performed by me. When my parts arrived on the second day (shipped on Monday, arrived on Tuesday), I followed the video instructions and had the job done in 1.5 hours saving myself almost $200 in service fees. The repairs worked for a very reasonable price. I will definitely use AppliancePartsPros.com in the future and tell all my friends about it too. 

Replaced both inlet valves. 

Replaced it with a new Valve Assembly,inlet. 

Was an easy R&R-procedure right under the machine's llid involving the removal of just 2/external-screws at the rear of the cabinet. Next, it is IMPORTANT in order to avoid confusion, simply remove the individual hoses and elect.-wires ONE AT A TIME, transferring each such item from the old to the exact same location on the new 4-valve Assembly. Then remount the new 4-valve Assembly to the aft-wall of the cabinet. Upon subsequent close-inspection it was found that the rubber-seals of the valves were cracked and leaking sufficiently to cause the malfunction.
