Drink with hesitation to appliance (7)
I believe the answer is:
toaster
'to appliance' is the definition.
(toaster is a kind of appliance)
'drink with hesitation' is the wordplay.
'drink' becomes 'toast' (toast is a kind of drink).
'with' is a charade indicator (letters next to each other).
'hesitation' becomes 'er' (sound used when hesitating).
'toast'+'er'='TOASTER'
(Other definitions for toaster that I've seen before include "At store (anag.)" , "Device using sliced bead" , "to get bread browner?" , "one that suggests health" , "wedding present?" .)
