Problem with equipment, needing good fruit pruned (6)
I believe the answer is:
glitch
'problem with equipment' is the definition.
'good fruit pruned' is the wordplay.
'good' becomes 'g' (abbreviation).
'fruit' becomes 'litchi' (genus lychee comes from).
'pruned' means to remove the last letter.
'litchi' with its last letter removed is 'litch'.
'g'+'litch'='GLITCH'
'needing' acts as a link.
(Other definitions for glitch that I've seen before include "sudden hiccup" , "Unexpected failure or error" , "Malfunction or snag" , "Minor mishap" , "Computer problem" .)
