I haven't experienced this problem but I would assume that it has something to do with the massive strain that you are putting on the power steering.
I was always told that you should never just turn the wheel when at standstill as you will very quickly destroy your power steering.
Try doing this on a car without power steering and you will feel just how much strain it puts on the power steering motor.
My 2c....please correct me if this is not the case though???
