Maybe store your defaults separately:

my %hash_defaults = ('a'=>0 , 'e'=>0 , 'i'=>0 , 'o'=>0 , 'u'=> 0,);
my %hash = %hash_defaults;

...

# Reinitialize
%hash = %hash_defaults;

... or restructure your loop code so that the initialization and reinitialization use the same code:

while (...) {
    my %hash = ('a'=>0 , 'e'=>0 , 'i'=>0 , 'o'=>0 , 'u'=> 0,);
    ...
};

... or use local (but that only works for global variables, not lexical variables):

use vars '%hash';

%hash = ('a'=>0 , 'e'=>0 , 'i'=>0 , 'o'=>0 , 'u'=> 0,);
...
do {
    local %hash = %hash;
    ... make some changes
};
... changes are forgotten
