I also have an LG Intellowasher with the same problem. I have fixed the problem a different way, probably the way described by Gary Winter is better.
I think washing in hot water deforms the drawer unit and causes water to go where it shouldn't.
1. Remove the soap dispenser unit and wash it thoroughly.
2. There is a thin hose leading from the soap dispenser unit to the drain in the back of the washer - make sure this hose is not blocked. Remove hose and run water through it.
3. Re-assemble everything into the washer.
4. This is the contraversial bit:
- The soap dispenser unit should be fully installed but the drawer is still removed.
- Silicone seal the gap between the soap dispenser unit and the plastic at the front of the washer, (Seal all round, but especially at the top. It should be possible to do this neatly, Try to get silicone fully into the gap, not just between the two pieces of plastic. (I flexed down the plastic at the top of the soap dispenser unit to get silicone into the gap.
5. Replace the drawer and wait a day before using the machine.
This worked for me, I can't guarantee that it will work for anyone else.
