It failed because either the change did not work well in many business settings, or it was inefficient (due to the inefficiency of the conveyer-belt system). A more accurate reason is that the circuits couldn't handle the traffic during peak hour. The customer's orders were regularly mixed up. The conveyer-belt system was not fast enough or efficient enough to handle it.

If Banana corresponds to the code 458124 you would have few possibilities of combination for the letters of BANANA: B=4; A= 5-1-4; N=8-2.
Now if BANANA becomes ANANAB does not matter the combinations of ANANA the last letter which is B should only be the number 4, so the code would have to be 4 in the last letter on the right side. So the code 421458 is not the right one.
