The gasket has cracked on the bottom and leaks. I have bought the new door/drum gasket. Where can I find instructions as to how to replace this large gasket/ring that stops water from leaking out the door

Replace the Door Gasket Seal.

Google

make mode replacement door seal
or
make model replacement parts

It may also be a crack in the outer drum body or one of the hoses or pump leaking, or just the drain hose split..

It sounds like you are fixing the wrong area. If water is coming down between the inner and outer door panel and following the wiring harness, the leak is inside the door. Either from the soap cup mounting or the rinse agent area which I think is the same unit on your model. There is a gasket behind that part. Also check the inner door if its plastic for any possible cracks.

there is a small pipe that runs from the drum buttom to the diafragma sensor water level
(it's a round thing 5" at the highst point in the machin) this item close a sircet and close the water inlet.
please chace for cracks or blocks in this pipe
all rhe best

CHECK YOUR DOOR GASKET / BOOT THAT IS MOUNTED IN FRONT OF WASHER DRUM. THE GASKET / BOOT MAY HAVE CRACKS, HOLES OR HAS COME LOOSE SOME HOW, ALSO MIGHT WANT TO CHECK ALL HOSE CONNECTIONS INSIDE AND OUTSIDE THE WASHER

Check you gasket around the door for cracks, if needed replace it or clean the door around the bottom and see if it helps.

. Using a good light , flashlight , etc. check your refrigerator and freezer door seals . This is the gasket that seals the door shut when closed . Look for cracks, tears, and possibly bumps in the gasket material. If you notice any of these , replace the door seal gasket . Furthermore , it is always best to replace both door gaskets at same time .

Open the door and gently pull on the grey rubber gasket and check all around it for holes / tears. There are three tiny holes in the 'wall' at the bottom that are supposed to be there, but you should not see any other tears. I just found a large tear on mine that causes leaks when I run very large loads. I am going to try to fix it with Gorilla Tape, otherwise I will probably have to buy the whole new gasket. It seems like it would be a real pain to replace!

if oil is leaking from the the top to bottom, check the gasket below the cover that has the daewoo name and sign on on top of the engine block. it could be cracked. replace with new one without any gasket sealant just replace the original and done

use a theromstat screwdriver,
ver small flat head, push it betwen the detent
and the clamp it should release right away

There is a ring that holds the door gasket in place on the outside of the front panel and another ring inside the drum (the ring has a spring on it that allows it to be stretched.

There are 2 tools that LG has that make the ring clamp easy to install/remove, but you can also use 2 pair or needle nose pliers (one to hold the ring at the spring and another to stretch the ring). Just be careful not to damage the gasket.

Also, when ordering the new door gasket, make sure you have your serial number handy. There are 2 versions of the door gasket (depending on the serial number).

Hope this helps, please rate my solution.
