I own an LG dishwasher about 2 years old (model LDF8874ST).
I have used this dishwasher regularly and have been really impressed with how quiet it runs. So it was very obvious when in the last couple of weeks it started to make a high-pitched noise when running (almost like whistling or singing). Can anyone please advise on possible causes?

Sure sounds like a worn-out bushing / bearing pack. The squeal will get worse with time and become a screech. If it is a worn out drive belt the issue is just as complex.
I have looked at LG's site for this product and it seems that this is definitely NOT a DIY job. LG offers tech support and possibly repair locations.
Unless you are an expert at replacing bearing packs / belts and have a lot of specialized tools, I would send it out for repair, or you might have the option of an in-house repair.
