How to Troubleshoot & Replace Lg AP4997045 / 4970ED4004G Dishwasher Door Hinge Spring

I purchased a set of new door springs and cable assemblies. The install was fairly easy but required shutting off the power disconnecting the power cables, water feed, and discharge lines so I could pull the dishwasher out enough to get the side panels off. Taking the side panels off was straightforward, just don't forget the two screws behind the door. I only had a cable broke on one side, but you could see some slight fraying on the second side, so it was a good idea to change both. I also changed the springs, but honestly I'm not sure it it was necessary since the old springs looked relatively new. I think the springs may get stretched over time, so I followed the lead of some others that did the same job. Putting the spring and cables on is easy and requires no tools at all. The job was not hard at all but did require some effort and patience. From start to finish including cleanup took around 45 minutes. 

Replaced both (right and left) springs and ropes (hinge cable assemblies). This required the water supply and drain hose to be disconnected. It was not necessary to disconnect the power supply - there was sufficient wire to pull the machine out without disconnecting. Remove the side panels and old parts. Install new parts. Button up and slide machine back in place. Reconnect water and drain hose. 

Ordered both springs and cables, very inexpensive. Disconnected water, electric, and drain. Removed front lower kick plate and anti fall down screws, pulled unit out and removed side panels. Replaced both door springs and cables (very easy job). Reinstalled in reverse order, any one could handle this job! 

I FIXED with my brain and hand. 

I did not know which part broke, but it was very obvious once I moved the Dishwasher out of the cabinet. The "cable" is nylon cord, so I imagine this would be sacrificial part on every machine. 

I removed the door and replaced the broken spring. I replaced the unbroken spring as well. It was the same age as the first, and I wanted to prevent a future problem. The entire job was less than 15 minutes including gathering tools. Now the door opens and closes easily again, and I spent less than $10.00 

I ordered both springs and cables then pulled the dishwasher out and removed the side panels. I discovered that the cables were broken on both sides and the springs appeared fine. Since I had them, I replaced both the springs and the cables and the door works just great now. 

It was really an easy repair once you get the dishwasher disconnected from drain/water supply/electrical and the out of cabinet. This part took 30-45 minutes due to tight fit and difficulty accessing water supply. Once dishwasher out of cabinet, removal of 5 screws per side, lifted off side panels, and access was simple. Took about 30 seconds to replace Hinge Cable. I ordered two and once the broken side finished, replace other side as well. It was showing significant wear and probably would have broken in 6 months or so. Once finished, replacing dishewaher and reconnecting took about 30 minutes. When reinstalled, took door apart to replace broken Deco Handle. Again simple just keep track of screws. There are three different sizes . Biggest problem is the extremely cheap parts LG puts into their $1000 dishwasher. 

I looked up my unit and reviewed the schematic drawing online at Appliance Parts Pro. Once receiving the parts, I Pulled out the dishwasher and removed side panels - didn't even have to disconnect anything. Removed broken parts and replaced them with the new - took about 10-15 minutes start to finish. Easy cheesy! Owning LG appliances I'm thankful to have found a resource like Appliance Parts Pro! I plan to use them for all my other LG repairs because they make it so easy to find parts. 

The most difficult part of this repair is removing and re-installing the dish washer. Without knowing what part failed and wanting the dishwasher unavailable for the shortest time possible I ordered springs and lanyards for both sides. If I could do it over, I would only order the lanyards as they are made of nylon cord and the likely failure point. I think it is very unlikely the the springs would ever fail. Once the unit is removed the side covers come off easily and provides open access to the spring/lanyard mechanism. Only one of the two lanyards failed but I replaced them both and would recommend doing so to anyone making this repair.
