The first data taking of EDELWEISS-II the Dark Matter search with bolometers, measuring simultaneously ionization and heat, indicate the presence of incomplete charge collection events underneath the electrodes. These events, interpreted as surface interactions limit strongly the sensibility to WIMPs. In this paper, we are describing the status of the different techniques that are under development in our collaboration to identify and reject this type of events.
