No matter what was the input - if all weights are the same, all units in hidden layer will be the same too. This is the main issue with symmetry and reason why you should initialize weights randomly (or, at least, with different values).

Web0. Main problem with initialization of all weights to zero mathematically leads to either the neuron values are zero (for multi layers) or the delta would be zero. In one of the comments by @alfa in the above answers already a hint is provided, it is mentioned that the product of weights and delta needs to be zero.
