Wa Wa without Dips

The second most common error for new students when learning how to use the Wa Wa is to use dips with each Wa of the hand. The dip is a technique where you start by playing a note bent and then quickly raising it. For some reason, it's almost universal for students to want to do a dip with each Wa... as if there were a string attached from their hands to their tongue. Though this is a valid option to couple these two techniques, the tonal change of the Wa is much more pronounced without the additional pitch change of the dip.
