LG no spares retention policy

I have an LG dishwasher about 10 years old and in mint condition. There is also a 10 year motor warranty. Took it to the LG service repair centre in Cape Town and after an assessment I was told no(door lock mechanism)spares available. Strangely, they did have the door 2 connectors. I queried the number of years that spares must be available for appliances and was told that LG does not have such a policy and that there is no such consumer law to force them to keep spares for 10 years per model. I queried the 10 year warranty on the motor and met with the same no spares retention policy answer. Most upset I did what I had to do from the start - phone local handyman technicians. I eventually found an appliance technician who came to my house and fitted a locking mechanism and 2 door connectors and now my old dishwasher is working as new and as before! No thanks to LG for not having nor keeping spares available! Shopping to perhaps buy a new replacement, most, if not all brands of appliances stated the availibilty of spares time on the websites.
